▼ Thirteen patients seen at Red Cross Children's and Maitland Cottage hospitals have under gone complex treatment for the significant deformities caused by meningococcal septicaemia. These patients underwent 62 surgical procedures between them. These procedures were directed at the treatment of sequelae of growth arrest alone and excluded amputations, contracture releases, skin grafts and flaps. The extent of the surgical problems caused by this disease brought about the realisation that a thorough review of the literature and follow up of these patients was required. This would hopefully be of use in assessing the outcomes of various surgical treatment options employed and in developing guidelines for the future management of physeal arrest in these patients.

▼ The goal of this thesis was to use non-invasive
quantifiable MR parameters of volume, signal intensity and T2*
relaxation time to predict the biomechanical or histological
outcomes of an ACL graft or ACL repair as a surrogate outcome
measure for healing. The main focus of this thesis was on
developing imaging methods for determining these MR parameters and
evaluating how these parameters could be used to assess ligament or
graft healing, in both animal models and in clinical trials. Our
first goal was to design an MR imaging method to predict the
structural properties of a healing ligament or graft in a large
animal model. We found that the linear combination of MR derived
volume and SI, as a surrogate for tissue integrity, predicted ex
vivo structural properties in a healing ACL or graft. As a further
refinement of this approach, it was found partial volumes defined
by equal intervals of T2*, predicted structural properties of a
healing ligament with the benefit of T2* being an inherent tissue
property with potential to be standardized across institutions. In
addition to being predictive of gross biomechanical performance,
T2* was also found to be predictive of histological outcomes that
have been associated with ligament healing on a microscopic level.
A complimentary study determined that these same imaging parameters
were not significantly associated with biomechanical performance of
degenerating ACLs in a human cadaveric population clustered around
50 years of age. Inherent differences with the macro or micro
anatomy of the degenerating ligaments may have lead to the
insignificant findings. Finally, as a translational step, the
combination of volume and SI were found to be predictive of
traditional outcomes, such as, the hop test, for patients that
received ACL reconstruction. The noninvasive MR methods presented
here for predicting the structural properties and histological
outcomes of the graft or ligament will allow researchers to
document healing longitudinally within a specimen in pre-clinical
animal studies. Furthermore, these findings may have implications
as a surrogate outcome measure in clinical studies for documenting
temporal changes within-patients and as a more quantitative method
for guiding rehabilitation.

▼ INTRODUCTION: Surgical repair of rotator cuff pathology has failure as high as 75% [1]. Biological factors such as stem cells and platelet rich plasma may improve the biological environment around the healing tendon [2]. We have investigated the use of a biocompatible and biodegradable electrospun polydioxanone (PDO) scaffold patch to restrain the spread of injected biological factors, and retain them in the desired locality. This study characterizes the degradation of PDO microfibrous patches in vitro. We have used imaging techniques, and high performance liquid chromatography to demonstrate the kinetics of PDO degradation as well as demonstrate the time scale of degradation in an in vitro representation of the physiological environment. METHODS: In-vitro weight loss: Electrospun polydioxanone patches were incubated in phosphate buffered solution (PBS) and weighed at intervals of 1 to 5 days over the course of 13 weeks. Weight loss of PDO samples was calculated as a percentage of the starting dry weight. Imaging: PDO samples were viewed in an Environmental Scanning Electron microscope (ESEM). Comparisons were made between fresh samples of PDO, and those degraded over a period of weeks in (PBS). The dimensions of the imaged fibres were measured and compared in order to characterize how they degraded. Fluorescent microscopy was used to image patches seeded with tendon-derived cells. These patches were incubated in PBS and imaged after 1, 2, and 4 weeks to demonstrate the adhesion of the cells to the electrospun fibres as the PDO degraded. High Performance Liquid Chromatography: HPLC was utilised to attempt to identify the final degradation product of polydioxanone, and to characterise the mechanisms by which it degrades. pH: PDO patches were incubated in PBS for a period of 8 weeks. At incremental time points, the pH of the solution was assessed. The Dynamic arm of the experiment involved replacing the PBS at each time point, in order to replicate the dynamic environment found in vivo. The Static arm maintained the same solution throughout the experiment. RESULTS AND DISCUSSION: The weight loss, pH, and imaging experiments provide evidence that PDO begins to significantly degrade at the 4 week time point. The ESEM images demonstrated the character of the PDO degradation, with degraded samples presenting short blocks of PDO in contrast to the long fibres of the fresh samples (Figure 3). It also provided evidence of the presence of live cells at the 4 week mark. The HPLC experiments also provided insight into the mechanisms of degradation and potential final degradation products. SIGNIFICANCE: The electrospun PDO structure maintains weight and pH well for 4 weeks which is the main window for physiological benefit from biological factors incorporated into the patch. Tenoblast cells maintain adhesion to the patch well, and the hypothesis formed from these results is that they will migrate onto the injury when exposed to physiological recruitment factors.

▼ Osteoarthritis (OA), the most common form of arthritis, is estimated to be in the top 5 leading causes of disability worldwide. Yet OA incidence is estimated to keep growing partly due to the overall worldwide trend of increased obesity and ageing population. Cartilage erosion, a hallmark of OA, has its onset in the traumatic events caused by incorrect biomechanical loading of the joint and the consequent biological response. Currently we still poorly comprehend the molecular pathophysiology of preclinical and clinical symptomatic OA, which consequently results in no current available therapy to prevent OA progression. We hypothesize that innate immunity and its receptor, in particularly toll-like receptors (TLRs), could be major drivers of OA disease progression and onset. The process could be initiated as a proinflammatory reaction against extracellular matrix (ECM)-derived damage-associated molecular patterns (DAMPs). DAMPs accumulate in avascular articular cartilage as a result of traumatization and degeneration, leading directly at their source to a reactive chondrocyte-mediated and TLR-dependent production of proinflammatory and algogenic secondary mediators, which then cause a secondary synovitis with consequent joint pain. For this propose, we collected cartilage and isolated primary chondrocytes from a total of 27 OA patients. Synovial fluid was obtained from knee meniscectomy, total knee arthroplasty (TKA) due to OA, and rheumatoid arthritis (RA) patients generating a total of 30 patient samples. HEK (human embryonic kidney)-blue TLR4 reporter cell line, primary OA chondrocytes, and cartilage explants were used for functional studies. Our results confirmed that TLR1, TLR2 and TLR9 expression is present in healthy primary chondrocytes isolated from articular cartilage, and derived from chondroprogenitors. During our chondrogenesis differentiation studies initial high expression of TLR1, TLR2 and TLR9 was significantly reduced to baseline levels.
We demonstrated that proinflammatory cytokine tumour necrosis factor alpha (TNF-α) is able to increase the expression of TLR2 in both healthy primary chondrocytes and mesenchymal stem cells (MSC) derived chondrocytes cultured for 21 days. TNF-α stimulation was demonstrated to induce cartilage degradation in de novo ECM matrix from pellet cultures of MSC-derived chondrocytes cultured for 21 days. This implicates TNF-α as an inducer of matrix degradation, with wide implications in the use of MSCs strategies in cartilage repair strategies for OA. Our study also added further evidence of a role for TNF-α in TLR-innate immunity in the OA synovial joint.
TLRs protein expression in cartilage between knee and first carpometacarpal (CMC-I) joints from OA patients was shown to be strikingly different. Our study demonstrated for the first time all TLRs being expressed at protein levels in articular cartilage from knee OA patients. Moreover, we demonstrated that their expression is up-regulated in a cartilage zone-dependent fashion accordingto the histological progression of…

▼ BACKGROUND: Total hip replacement (THR) is one of the most successful orthopaedic procedures performed worldwide (Miller 2008). The number of joint replacements performed in Africa is increasing but outcomes reported in sub-Saharan Africa, excluding South Africa, are sparse (Dossche 2014). Coupled with an anticipated rise in the prevalence of total hip replacements resulting from trauma, infection and the aging population (Elders 2000, Keruly 2001), there has been no corresponding increase in the health facilities offering specialised orthopaedic services. Zambia has not been spared as there is an information gap regarding information on patients that have undergone Total Hip Replacement and their functional outcomes. The aim of this study was to determine the functional outcomes of patients based on the Harris hip score after total hip replacement
MATERIALS AND METHODS: 31 patients were enrolled in the study by using convenient sampling from hospital records. Patients that met the criteria were then invited to join the study. A standardised structured questionnaire was used to obtain the biophysical profile, pre and postoperative co-morbidities. Functional outcome of the patient was then determined by using the HHS and the results obtained tabulated thereafter.
RESULTS: Twenty males and females were enrolled. The minimum age was 19 years, maximum 78 and mean age was 48.8years. Ten patients were found to be hypertensive, 8 HIV positive, 1 Diabetics Mellitus, 5 had Sickle cell trait while the remaining 7 had no pre-existing medical conditions. Pain was the major indication of surgery. Postoperative complications were either wound infection (38.7%) or hip dislocation (3.2%). Twenty three rated the operation a success, 8 said it was a failure. The Harris Hip Score ranged from poor to good.
CONCLUSION: Pain was the main indication for surgery. Functional outcomes using HHS ranged from poor to good. Patients were generally satisfied with the outcome after Total Hip Replacement. No association was found between the HHS and the patients’ biophysical, pre-existing comorbidities, postoperative complications and duration from time from surgery.

▼ Background: Low back pain (LBP) is an important cause of disability and work absenteeism. World health organization defines Disability as impairment of activity-limitations, participation restriction. The majority of low back pain stems from benign musculoskeletal problems and it is referred to as non-specific low back pain; this type may be due to muscle or other soft tissue sprain or strain. Over 99% of back pain fall within this category. Oswestry Disability Index (ODI) was used to evaluate the quality of life in individuals with low back pain.
Objectives: To establish the effect of low back pain on daily living activities among the patients seen at University Teaching Hospital, Orthopedics clinic, Lusaka, Zambia using the Oswestry Disability Index.
Methodology: This was the cross sectional study that was conducted at University Teaching Hospital, Orthopaedic clinic. A total of 167 patients were enrolled both female and male, and evaluated using ODI. Sex, height, weight, age and occupation were used as independent variables. ODI questionnaires were used as an instrument for collecting data.
Results: 37%of the patients were males and 63% females. It was found that among the variables; sex, height, weight, age and occupation, occupation was significant in association with low back pain. It revealed that 75% of patients with severe low back pain were from informal sector of occupation while 18% were from formal sector. Additionally, it was also noted that those with high BMI regardless of gender had more disability due mechanical low back pain as compared to those with low BMI.
Conclusion: The results showed that there is an association between occupation and ODI. 75% of the candidates with mechanical low back pain were in informal sector and 18.8% were in formal. Furthermore, males were more severely affected than females. Additionally, obesity revealed more disability as compared to those patients with normal weight.

▼ Vid rehabilitering är det viktigt att veta om och när muskler vid det skadade området återfår sin styrka. Gällande axelskador finns det idag ingen etablerad metod för mätning av muskelstyrka. I de metoder som testats är vissa attribut inte önskvärda och därför vill man på Karolinska universitetssjukhuset, Huddinge ta fram en ny, förbättrad metod. I metoden ska man kunna mäta en patients muskelstyrka och se skillnaden mellan mätningar över en tidsperiod. Av intresse är den maximala muskelstyrkan samt muskelstyrkan vid 45° abduktion och flexion. Projektet går ut på att ta fram en prototyp som kan användas enligt metoden och se om prototypen är lämplig. En testgrupp bestående av både friska och axelskadade personer genomförde tester för prototypens noggrannhet hos vinkelmätning, prototypens användbarhet samt lämplig vinkel för maximal muskelkraft i axeln. Resultatet visade att prototypens noggrannhet var inom det godkända intervallet för metoden. Användbarheten var också godkänd då alla testpersoner kunde använda prototypen inom de begränsningar vi satte. Vi såg ingen övergripande trend där maximal muskelkraft i axeln erhölls vid 45° även om det stämde för vissa individer. För vidare arbete och ökad validitet krävs fler studier med större testgrupper.
During rehabilitation, it is important to know if and when the muscles in the injured area have regained their strength. Regarding shoulder injuries, there is currently no established method of measuring muscle strength. In the methods tested, certain attributes are undesirable. Therefore, Karolinska Universitetssjukhuset, Huddinge is looking into developing a new, improved method. In this method, one should be able to measure a patient's muscle strength and study the difference in measurements over time. The maximum muscle strength and the muscle strength at 45 ° of abduction and flexion is of interest. The project is to produce a prototype that can be used according to the new method and see if the prototype is appropriate. A test group consisting of both healthy and shoulder injured patients performed tests regarding the prototype accuracy of angular measurement, prototype usability and appropriate angle for maximum muscle strength in the shoulder. The result showed that the prototype accuracy was within the approved range of the method. Usability was also approved as all test subjects could use the prototype within the limits we set. We did not see an overall trend in which maximum muscle force in the shoulder were obtained at 45 °. For further work and increased validity, further studies with larger test groups is required

▼ Tendon injuries and tendinopathy are a growing problem in the aging but physically active population as well as athletes. Tendons have highly ordered matrix and undergo complex changes during the remodelling phase of tendon healing. Moreover, anaerobic metabolism and poor vascular network contribute to slow adaptation of tissue to the remodelled matrix which consequently results in slow and compromised healing. Such a destitute and slow healing process necessitates development of new and effective therapies and to combine therapies to obtain possibly synergistic effects. Addressing this clinical requirement, the work presented in this thesis investigates the role of two emerging treatment options, platelet rich plasma (PRP) and mechanical loading, on tendon healing. The effects of PRP, a rich autologous source of growth factors, on tendon cells was studied by modelling important stages of tendon healing in vitro. Key parameters such as cellular migration, chemotaxis, viability and senescence were investigated by means of different culturing and staining techniques together with microscopic analyses. PRP significantly increased migration and chemotaxis in human primary tenocyte culture. Moreover, PRP protected human tenocytes against challenging environments created by known tendon damaging drugs, dexamethasone and ciprofloxacin, as well as the injury relevant condition of hypoxia. Concurrently, an in vitro rat tail tendon injury model and static loading device was developed to assess the effect of static mechanical loading and PRP on the biochemical and biomechanical properties of tendon at the tissue level. This in vitro system was also used to investigate the synergistic effects of PRP and mechanical loading on tendon healing. Both PRP and mechanical loading helped to improve the biomechanical and biochemical properties of damaged tendon in vitro. In conclusion, the positive effects of PRP on key cellular parameters such as cell survival, migration and chemotaxis and also mechanical and biochemical properties of tendon tissue make it an important option for faster and less invasive tendon treatment. Additionally, an in vitro tendon injury model together with the mechanical loading device provide a new tool to investigate the mechanical boundary conditions suitable for treating different types of tendon disorders. The findings from the current study points towards the significant contribution of PRP and mechanical loading to the healing process in tendons and could serve as a promising starting point for developing integrated therapeutic modalities to improve the quality and speed of recovery from tendon injury.

▼ Surgery is a difficult skill to teach and even more difficult to assess. In the context of orthopaedic surgery, the Oxford unicompartmental knee arthroplasty (OUKA) is a commonly performed and technically challenging procedure with a variable and sometimes unsatisfactory revision rate. Thus there is a need to develop methods for optimising performance in this procedure. This thesis aims to use this procedure to explore ways of improving teaching methods and assessment methods, and the use of novel technologies to impact surgical performance. No validated technical skill assessment system currently exists to evaluate surgical performance during OUKA. A consensus-based framework of expert opinion (Delphi methodology) was therefore used to determine the essential technical steps of OUKA to aid development of a technical skill assessment system. A procedure-specific assessment scale named the Oxford Arthroplasty Technical Skill Score (OATSS) was produced. Two clinical studies were conducted to demonstrate the inter-rater reliability and construct validity of OATSS in the real operating theatre. This is the first time that a procedure-specific assessment scale has been developed and validated for a complex orthopaedic procedure. The Delphi methodology was also used to identify important radiographic parameters that could be used to predict clinical outcome following OUKA. Two cohort studies used post-operative radiographs of "failed" and "poorly functioning" OUKA cases (with matched controls) to identify several radiographic parameters that can predict the increased risk of a poor clinical outcome. A virtual reality (VR) based simulator (called ViTAL) was developed to teach the cognitive skills necessary for performing the OUKA procedure. This software-based learning environment was used in a randomised controlled study to assess its training effectiveness. This demonstrated that, when used alongside existing teaching modalities, ViTAL resulted in better acquisition of cognitive skills in novice trainees. A randomised controlled study was subsequently undertaken using anatomic dry-model bones in a surgical skills laboratory to determine the effect of cognitive skills training using the ViTAL simulator on the ability of orthopaedic trainees to perform the OUKA procedure. The previously validated OATSS assessment scale was used to evaluate surgical performance. Results demonstrated that this type of training not only improved acquisition of cognitive skills, but also resulted in better technical skill performance during OUKA procedures. This demonstrates, for the first time, the effectiveness of a purely cognitive VR-based simulator for improving technical skills during arthroplasty surgery. Patient-specific instrumentation (PSI) is a novel and exciting technological development within orthopaedic surgery. A prospective RCT was performed to compare OUKAs implanted using PSI with those implanted using conventional instrumentation. Intra-operative measurements, together with post-operative radiographic analyses, were…

▼ During the period July 1994 to September 1998 surgery was carried out on seventy-six hips in seventy-five patients that sustained posterior fracture-dislocation of their hip joints. During my training I was personally involved in thirteen of these cases and was the primary surgeon in seven cases. Because of my personal interest in these patients Dr Siboto provided me the records of all seventy-five patients for my scrutiny. While he has carried out the surgery on all but the seven cases which I operated on, the literature review, the correlating of the data and all of the interpretation is my own personal work. At surgery prospective records were kept of the degree of comminution of the fracture, the presence of marginal impacting and the presence of fragments in the joint. Fractures were then classified according to Thompson and Epstein (1951). The surgical time was recorded as well as the nature of the associated acetabular floor fracture when it occurred. Anatomical reconstruction was always attempted including elevation of marginal impaction and bone grafting where appropriate. Fragments were only discarded when too small and unattached to permit their inclusion in the reconstruction. All patients had neurological assessment preoperatively and their Sciatic nerves were explored and the state of the nerve recorded at surgery. The process of formulating this dissertation took place over a two-year period from September of 1997 until June of 1999. As a result, the number of patients examined in relationship to a specific
subject is not constant but alters according to the group under scrutiny at that particular point in time. An initial review of sixty cases in September 1997 was carried out and then an additional fifteen patients up until September 1998 were included where relevant. The aim of carrying out this study was to gain a better understanding of this injury so that we could formulate a management protocol for our patients in Groote Schuur Hospital. First of all, I reviewed the literature to discover exactly what has been written about this pathology. In the process I hoped to gain a better understanding of the problem and attempt to define a more concise approach to the injury by consolidating the broad array of articles written on this
subject. Then by reviewing our findings in our large series of patients I aimed to discover whether we were encountering similar problems to the surgeons who had preceded us and whether we had made any new discoveries that might positively contribute to the future management of these patients.

▼ Aim: To preliminary validate a questionnaire that was developed in this study. The questionnaire was designed to investigate, if patient’s perception of appearance of their Boston corset influences their compliance, in a positive or negative way. Background: Going through brace treatment brings a lot of feelings for adolescent idiopathic scoliosis patients. Not having a “perfect body” decreases body image and self-esteem. It is highly likely that by changing the patients’ perspective of their brace into liking the appearance of it; the probability of positive compliance will increase in patients. Method: Mixed method approach was used to develop and validate a new questionnaire. The development and validation were done using literature, expert and patient groups. Qualitative data was evaluated, and quantitative data was analyzed using Pearson’s correlation coefficient and Cronbach alpha. Result: Preliminary validated questionnaire was created. The group used for validation were all idiopathic scoliosis patients, four boys and four girls, between the age of 6 and 15 years old. Conclusion and outlook: Further validation of the questionnaire is required before applying on future studies. Preliminary results indicate that patients who like the way they appear in their brace are also compliant.
Syfte: Att preliminär validera ett frågeformulär som utvecklades i denna studie. Frågeformuläret var utformat för att undersöka om patientens uppfattning om deras Boston korsett påverkar deras compliance på ett positivt eller negativt sätt. Bakgrund: Att genomgå korsettbehandling innebär många känslor för ungdomar med idiopatisk skolios. Att inte ha en "perfekt kropp" minskar kroppsbilden och självkänslan. Det är högst sannolikt att genom att förändra patienternas perspektiv på deras korsett till att tycka om utseendet på den; så ökar sannolikheten för compliance med positiva känslor. Metod: Mixed Metod användes för att utveckla och validera ett nytt frågeformulär. Utvecklingen och validering gjordes med hjälp av litteratur, expert- och patientgrupper. Kvalitativa data utvärderades och kvantitativa data analyserades med användning av Pearsons korrelationskoefficient och Cronbach alpha. Resultat: Ett preliminärt validerat frågeformulär skapades. Gruppen som användes för validering var idiopatiska skoliospatienter, fyra pojkar och fyra tjejer, mellan 6 och 15 år gamla. Slutsats: Ytterligare validering av frågeformuläret krävs före användning i framtida studier. Preliminära resultat indikerar att patienter som tycker om hur de ser ut i deras korsett också följer compliance med positiva känslor

▼ Magnesium (Mg) and its alloys were initially investigated as resorbable orthopaedic biomaterials more than a century ago. However, their use was abandoned due to rapid corrosion resulting in mechanical failure and excess hydrogen production. Whilst recent advances in manufacturing processes have led to a renewed interest in the field of Mg based biomaterials, the corrosion behaviour remains the feature that is the most difficult to control and characterise. In particular, the development of these materials is hindered by an inability to use in vitro techniques to accurately predict the behaviour of Mg alloys in an in vivo environment. Furthermore, the biocompatibility of the materials is often underemphasised in favour of the assessment of corrosion behaviour. The purpose of this thesis was therefore two-fold. Firstly, the aim was to develop and optimise a series of both in vitro and in vivo methodologies that would allow the prediction of corrosion rate, and the assessment of the biocompatibility of Mg materials. Secondly, these methods would be used to identify Mg alloys that could be investigated for use as orthopaedic biomaterials.
The initial portion of this study focussed on the development of an in vitro immersion method that could be used to cautiously predict the in vivo corrosion rates of Mg alloys. The in vitro protocol involved the use of three different solutions with varying degrees of physiological relevance, the results from which were compared to the corrosion occurring in an in vivo subcutaneous environment. The solution providing the most comparable corrosion rates was identified and subsequently utilised to select four slowly corroding Mg alloys for further investigation.
Preliminary analysis of the biocompatibility of these four alloys was carried out using an in vitro cell culture technique. The results of this investigation indicated that the use of a closed cell culture environment is likely to reduce cellular viability due to the increased pH and osmolality associated with rapid Mg corrosion. Accordingly, it was concluded that whilst cell culture techniques can provide results indicative of the degree of biocompatibility, they must be used in conjunction with the results of in vivo investigations for a comprehensive understanding of the true biocompatibility of Mg based materials. Consequently, an in vivo soft tissue study was undertaken involving the implantation of the four Mg alloys in both intermuscular and intramuscular locations in Lewis rats. This investigation indicated minimal hydrogen production associated with the Mg alloys, and biocompatibility equivalent to that seen with the implantation of a biomedical Ti alloy (Ti-6Al-4V).
The results from both the in vitro and in vivo studies identified Mg-1Zn and Mg-0.4Ca as the alloys exhibiting optimal characteristics for further investigation as orthopaedic implant materials. An intraosseous study was carried out involving the implantation of these alloys into the shaft and epiphyseal region of the ovine tibia. The results indicated…

▼ INTRODUCTION: A recent area of interest has become adipose tissue of the bone marrow. Unlike fat found elsewhere in the body, it is able to respond to its microenvironment by expanding, contracting, and even releasing hormones of its own. The marrow adipose tissue (MAT) increases with age and even within anorexic patients. Changes in MAT may be directly linked to bone tissue, since both adipocytes and osteoblasts share a common progenitor cell population. This is supported by recent results showing that the constitutive deletion of the MRTF-A (Myocardin related transcription factor A) gene not only led to leaner mice leaner but also had a bone phenotype. The bones were shorter and had decreased bone mass; the female mice were more susceptible to osteopenia. It is unclear as to how this bone phenotype will respond to fracture repair, a coordinated process that is dependent upon differentiation toward the osteoblast lineage. Therefore, both male and female MRTF-A knockout (KO) and wild type (WT) mice were examined in a fracture study.
METHODS: Male and female mice (KO and WT) aged 8-16 weeks were fractured using a closed, stabilized fracture model. Tissues were harvested as post-operative day 14, 21, and 37. Radiographic films and histological assessment were completed at each time point to visualize the progression of fracture repair. Gene expression studies using RT-qPCR were all done at time points 14 and 37. Results were compared between genotype and sex.
RESULTS: Fracture calluses between WT and KO male and female mice appeared nearly identical via X-ray, suggesting that MRTF-A did not affect fracture repair. Only at the later time points did the histology show females had increased MAT regardless of genotype. Immunofluorescence with perilipin further confirmed this. Adipogenic, chondrogenic, and osteogenic markers also yielded differences in relative mRNA expression between the sexes.
CONCLUSIONS: The MRTF-A KO mice did not show delayed or altered fracture repair compared to the WT mice. However, the data suggest difference in MAT deposition between male and female mice. Further work is necessary to fully understand this sex difference.

▼ Articular cartilage accrual occurs predominantly during childhood and adolescence, with the magnitude, direction, and pattern of internal joint loads directing the cartilage growth. If any of these factors of the joint loading are abnormal, it can predispose these children to degenerative knee joint disease as an adult. To provide an estimate of the internal joint loads, a paediatric-focused, static optimization-based lower limb model was developed, compared to recorded sEMG, and analyzed for sensitivity to changes in ground reaction force and muscle attachment site.
The model was found to provide consistent predictions of joint contact force predictions ranging from 0.01 to 0.35xBW with standard error of 8% to 17%, with the exception of left knee medial-lateral shear at 108%. Muscle force predictions related well to sEMG, with the standard error ranging from 14% to 36%, except for gastrocnemius lateral at 104%. The model was sensitive to variations in the ground reaction force vector, with a maximum deviation of 0.11 xBW determined as a result of a ±5% variation in GRF.
The model was found to be sensitive to clinically relevant deviations in muscle attachment site. Maximum knee anterior shear was significantly changed (p < 0.05) with a 1cm posterior quadriceps insertion deviation, maximum lateral shear with a posterior semimembranosus deviation, and maximum medial shear with a posterior or medial quadriceps deviation. No deviations caused statistically significant changes in compression. Statistically significant change in joint contact force could not be predicted based on changes in muscle moment arm, but could be indirectly predicted by the predicted muscle forces.
The model’s uniform convergence and sensitivity to variations in input indicate that the model is sufficiently reliable and robust. This sensitivity suggests that the model is capable of adapting to altered loading conditions and musculoskeletal geometry, either due to deformity or corrective procedure. The model was therefore deemed to be a strong platform for developing clinically specific models for analyzing internal knee loads in a diverse paediatric population.

▼ Menisci are C-shaped fibrocartilaginous tissues responsible for distributing tibial-femoral contact pressure and are crucial for maintaining healthy joints and preventing osteoarthritis. Meniscal damage can be caused by age-related degradation, obesity, overuse from athletic activities, and trauma. Due to their primarily avascular nature, once damaged there is limited healing capacity and surgical intervention is often required. Limited technologies exist to replace damaged menisci, and standard treatment is to leave asymptomatic damage alone or perform partial meniscectomies, however, these treatment options lead to increased risk of OA. Attempts at tissue engineered meniscal scaffolds, and replacements have had mixed results due to design limitations and inability to recapitulate native tissue's material properties, shape, and pressure distribution. This project strives to create an artificial meniscus from a polystyrene-polyethylene oxide diblock copolymer. It is hypothesized that this hydrogel can be tuned to have material properties similar to those of the native meniscus. Furthermore, it is hypothesized this hydrogel can be molded into a 3D meniscal construct, implanted into the joint, and have similar pressure distribution properties as the native meniscus. Thus, the aims of this project are: 1) Mechanical comparison of a polystyrene-polyethylene oxide diblock copolymer TPE hydrogel to native meniscal tissue. 2) Develop a 3D meniscal construct which can be implanted into an ovine model and assess load distribution properties including contact area, mean pressure, and max pressure in both the medial and lateral hemijoints. If the goals of this project are met, there would exist a 3D TPE hydrogel construct that mimics the mechanical and functional properties of the native human meniscus. This meniscal replacement could provide a revolutionary addition to the field of osteoarthritis and meniscal injury.

▼ Tässä tutkimuksessa tutkittiin retrospektiivisesti Sairaala Ortonissa, Kymenlaakson keskussairaalassa ja Peijaksen sairaalassa vuosien 2004-2014 välisenä aikana leikattujen 13 potilaan ja 15 yksilöllisesti suunnitellun erikoisproteesien onnistumista anatomisesti ja toiminnallisesti poikkeavissa tilanteissa. Potilastapauksien taustalla olevia polven sairauksia olivat muun muassa post-polio-syndrooma, akondroplasia ja osteogenesis imperfecta. Tässä tutkimuksessa leikkausta ennen otetuista röntgenkuvista määritettiin nivelrikon aste Kellgren & Lawrence –asteikolla ja laskettiin mekaaninen akseli. Elämänlaatua ja toimintakykyä arvioitiin tähän tutkimukseen protetisaation jälkeen WOMAC-, OKS- ja KSS-kyselyiden avulla. Neljällä potilaalla käytettiin yksilöllisesti suunniteltuja erikoisproteeseja, jotka sallivat yliojennuksen; viidellä potilaalla käytettiin anatomisiin poikkeustilanteisiin sopiviksi muokattuja proteeseja ja neljällä potilaalla käytettiin muilla tavoin yksilöllisesti suunniteltuja proteeseja. Vain viidellä potilaalla oli ennen leikkausta täytetty KSS-kysely, heillä KSS-tulos parani keskimäärin kliinisessä KSS:ssa 35 pistettä ja toiminnallisessa KSS:ssa 9 pistettä. Potilastapaukset olivat niin yksilöllisiä, että tarkoituksen mukaista tilastollista parametrien vertailua ei pystytty muodostamaan. Tutkimuksen perusteella voidaan sanoa, että yksilöllisesti suunnitellut erikoisproteesit parantavat elämänlaatua ja toimintakykyä, mutta lisää tutkimusta tarvitaan aiheesta luotettavan tutkimusnäytön saavuttamiseksi.

▼ Metal-on-metal hip resurfacing arthroplasty (MoMHRA) is an alternative treatment option to total hip arthroplasty (THA), especially in the young and active. Despite the early successful results, reports of adverse soft-tissue reactions around the MoMHRA have caused increased concern. These reactions have been termed pseudotumours and have been shown to be associated with increased wear. However, their incidence and aetiology is not known. The broad aims of this thesis were to 1) determine the clinical impact of pseudotumour; and 2) identify ways of reducing the risk of pseudotumour. The clinical impact was determined by examining the incidence and prevalence of pseudotumours needing revision and the subsequent outcome following revision. At the Nuffield Orthopaedic Centre, the 10-year survival of the BHR, commonest MoMHRA used, was 87.1% (95%CI: 83.0% to 91.2%) and the 10-year incidence of revisions due to pseudotumour was 7.5% (95%CI: 4.3% to 10.7%). In a prevalence study of two tertiary referral centres, pseudotumour was identified as the most common revision indication. An outcome based, case-control study characterised outcome following revision due to pseudotumour as inferior to that following revision for any other failure mode, and inferior to the outcome of matched primary THAs. The inferior outcome was associated with the extensive tissue damage at revision. Risk factors contributing to development of pseudotumour were found to be both patient and surgeon related. Patient factors significantly increasing risk included female gender and small component size. Case control studies demonstrated two surgical factors that were associated with significantly increased risk; cup malorientation and a reduction in head neck ratio (HNR) at operation particularly in females. Furthermore, evidence based recommendations were provided on optimum cup orientation and screening practice. Surgeons should aim for a radiographic cup inclination/anteversion zone of 45°/20° ± 10°. Patients with mal-positioned cups, those with high HNR prior to surgery, and those that had significant HNR reduction with the MoMHRA should be considered at increased risk of developing a pseudotumour. An ex vivo study demonstrated that the majority of pseudotumours occur due to high prosthesis wear, and result from an exaggerated innate response with an accompanying variable immune response. However a small but significant number of pseudotumours (20%) were observed with low wear and a prominent immune response. Furthermore, the cups oriented within the optimum zone were associated with less wear. Hence, subsequent in vivo research focused on providing evidence-based guidance on how to achieve the target cup orientation and factors to consider in minimising the scatter in cup orientation observed following hip arthroplasty. This great scatter was mostly due to two factors: 1) the variability between surgeons at orientating a component at implantation and 2) the difference in the pelvic position between implantation and radiographic assessment. The…

▼ <h2>Abstract</h2>
Introduction
Wedged shoe insoles are used as a treatment for different problems in order to change the ground reaction force. They can secondary cause different loading patterns under the foot compared to normal. No previous study has, to the author’s knowledge, clinically evaluated the plantar foot pressure with different full-length wedges in normal persons.
Purpose
The purpose was to evaluate the plantar pressure with different degrees of full-length wedges in normal persons.
Method
Twenty persons with normal feet have participated in this single blind study. Wedges were produced clinically in four different shapes, 3° valgus, 0° flat, 3° varus och 6° varus. The test persons were told to walk with the wedges in their comfortable pace in a randomized order. The plantar pressure was measured in the medial and lateral heel as well as in the first and fifth metatarsal head.
Results
The results show significant increased mean pressure for varus wedges compared to flat as well as valgus wedges, in the area of the medial heel and first metatarsal joint. Also, valgus wedges show significant increased mean pressure compared to flat condition in area of the medial heel. There is no correlation between wedge height and mean pressure for any of the wedge conditions.
Conclusion
Treatment with wedges leads secondary to increased mean pressure for varus wedges compared to flat as well as valgus wedges, in medial heel and first metatarsal joint. Furthermore, valgus wedges show increased mean pressure compared to flat condition in medial heel. Patients sensitive to high plantar pressures in these areas should be treated with caution. Further studies are recommended.

▼ The patellofemoral joint (PFJ) is a common source of problems in Orthopaedics and is the source of poorly defined pain and poor function in both normal and replaced knees. Before problems of the PFJ can be fully comprehended a better understanding of the basic form and function of the PFJ is required. The aim of this thesis therefore is to investigate the shape and kinematics of the PFJ and their inter-relations in both normal and replaced knees. The first part of this thesis was concerned with the shape (or form) of the PFJ. Species from the human ancestry over the previous 400 million years were assembled and measurements taken from three dimensional, CT reconstructions, allowing the descriptions of evolutionary changes in the shape, and orientation of the patellofemoral joint in relation to the tibiofemoral compartments. The study chronicled the dramatic changes that occurred in relation to the adoption of the erect bipedal hominin stance which has resulted in varied anatomy at the PFJ, predisposing it to a wide range of pathologies. The articular surface geometry of normal human patellofemoral joints (bone and cartilage) were compared with those of total knee replacements, and patellofemoral joint replacements. Mapping of the trajectory of the apex of the trochlea groove revealed significant differences between native and replaced knees, with the trajectory being orientated laterally in normal knees and either centrally or medially in replaced knees. The second part of this work was concerned with the kinematics (or function) of the PFJ. With current technology it is impossible to measure coronal plane PFJ kinematics with any accuracy in both native and replaced knees. A novel method was developed combining Motion Analysis and UltraSound (MAUS). Validation experiments were undertaken that demonstrated acceptable error (1.8 mm). The MAUS technique was used to show statistically significant differences between the coronal plane kinematics of the patella in normal and replaced knees. In particular in some arthroplasty patients, the patella tracked in the opposite direction to that in normal subjects. The abnormal kinematics were a manifestation of non-anatomical joint replacements. This demonstrates that form and function are closely related. The interaction between form and function in the knee was further investigated using patients with anterior knee pain. Assessment was made of the relationship between patellar subluxation and multiple bony, cartilaginous and soft-tissue factors potentially predisposing to subluxation. The percentage of engagement of the patella in the trochlear groove in knee extension showed the strongest relationship with subluxation, with subjects less than 30% engaged tending to subluxate. This suggests that the most important factor in preventing subluxation is patellar engagement. A clinical study is now required to assess the effect of surgery aimed at improving engagement. The detailed insights into the variability of form and function in the PFJ obtained throughout this thesis will…

▼ Purpose: To explore the perspectives of occupational therapist’s practising in the acute orthopaedic setting in Ireland.
Method: Five occupational therapists working in the acute orthopaedic setting were interviewed using a semi-structured, open-ended interview protocol. Data were analysed using thematic analysis informed by a qualitative research methodology.
Results: Fives themes emerged following data analysis: Core beliefs of occupational therapy, role definition in the acute orthopaedic setting, enhancing practice through effective communication and supportive multidisciplinary relationships, perceptions of occupational therapists- motivations and frustrations and the growth and development of occupational therapy. Participants shared their personal experiences of practising in the acute orthopaedic setting, provided examples of how they envisage their role within the setting, discussed the prerequisite for effective communication and supportive relationships with colleagues. Finally, they described the changes they perceived as being necessary for the development of occupational therapy to occur.
Conclusion: The complexities of practising in the acute orthopaedic setting were explored. Inadequate opportunities to engage in continuous professional development, insufficient funding and limited staffing and resources were highlighted as areas that inhibited the growth and development of the profession. The impact of inadequate service provision is discussed with recommendations for future research. It is suggested that the findings from the current research can be used to contribute to a greater understanding of the role of occupational therapy within the acute orthopaedic environment. Additionally, it is hoped the study will empower emerging therapists to explore innovative ways of describing the valuable contribution of occupational therapy, within an increasingly competitive health service.

▼ Designing orthopaedic implants to reconstruct native anatomy and function continues to be a major challenge in the development of new products. This thesis provides insights and suggestions for designing next generation knee arthroplasty with a focus on native joint kinematics. Like in many other specialties, biomimetics is the ultimate objective in joint reconstruction.
Knee arthroplasty is the most successful treatment option for severe osteoarthritis, providing patients with a reliable solution to relief pain and regain mobility. However, native joint function is not fully restored and for an aging population with growing interest in demanding activities, several limitations are present. Particularly, existing total knee arthroplasty (TKA) delivers kinematic deficits, associated with abnormal feeling of the knee, following joint surgery. These limitations are related to sacrificed ligaments, and none-anatomic geometries of current implant designs. Mostly, the anterior cruciate ligament (ACL) is sacrificed and its function is lost. Therefore, a biomimetic process was implemented to reverse engineer articular surfaces, by directly incorporating native knee kinematics.
For the first aim, we designed a biomimetic implant that would preserve all major ligaments of the native knee joint. Therefore, an anatomically designed femoral component was virtually moved through native knee kinematics, to carve out a tibial articular surface, through the biomimetic process. This anatomical surface was incorporated into a novel implant, specifically designed to preserve the native ACL.
For the second aim, we established a dynamic simulation platform to reliably evaluate implant design variations and the effect of ligaments. Knee kinematics, driven by ligament function and contacting implant geometry, allowed for comparison of different knee arthroplasty systems, against in vivo and simulated native knee motion. The first computational study revealed that a biomimetic, bi-cruciate retaining (BCR) implant provides activity dependent kinematics, similar to healthy knees in vivo, during deep knee bend, chair sit and level walking. This was in contrast to symmetric BCR systems, which nonetheless showed kinematic improvements over ACL-sacrificing implants. This indicates that restoring anatomic knee geometry together with ACL preservation is required for optimal implant function. The second computational study showed that a novel ACL-substituting mechanism could improve kinematic deficits of contemporary PCL-retaining (ACL-sacrificing) implants. ACL-substituting and ACL-retaining implants both provided similar improvements over the ACL-sacrificing implant in comparison to a native knee model. This was shown during walking, stair-ascent, chair-sit and deep knee bend simulations, indicating that ACL-substitution may be a valuable treatment option when ACL preservation is not feasible.
For the third aim, we evaluated an extended treatment indication for unicompartmental knee arthroplasty (UKA), via in vivo kinematic analysis, using a…

▼ Abstract â Burnout among Australian orthopaedic trainees and the factors associated with itAim: To study burnout prevalence and associated factors among Australian orthopaedic trainees.Method: We conducted a nationwide cross-sectional observational study using a 32-question survey consisting of a self-developed item set of 10 questions and a 22-question validated instrument (Maslach Burnout Inventory â Human Services Survey) to assess burnout. The survey was emailed to 236 orthopaedic registrar members of the Australian Orthopaedic Association. Results: 51 trainees completed the survey, yielding a response rate of 22%. Burnout prevalence among orthopaedic trainees was high (52%) despite high career satisfaction (89%). 55% of trainees were dissatisfied with their work-life balance. Burned out trainees were more likely to be dissatisfied with their choice of
orthopaedics as a career (p=0.004) and with their work-balance (p=0.021) compared with their non-burned out counterparts. Females were more likely to be burned out than males and non-married trainees more than married trainees, although these associations were not significant. There was no observed trend for burnout with relation to seniority in the training program. Discussion: Burnout prevalence among Australian orthopaedic trainees is high despite high career satisfaction. There may be a role for active interventions aimed at combating burnout and improving work-life balance among orthopaedic trainees. Abstract â Job satisfaction among Australian orthopaedic surgeons and the factors associated with itIntroduction: High job satisfaction has positive outcomes for patients, health institutions and surgeons. There has been no research into job satisfaction primarily among Australian orthopaedic surgeons and its associated factors. The aim of this study was to assess job satisfaction and associated factors among Australian orthopaedic surgeons. Method: We conducted a nationwide survey using a 24-item questionnaire consisting of a self-developed item set of 14 questions and a 10-question modified version of Warr-Cook-Wall Job Satisfaction instrument to assess job satisfaction. The survey was emailed to 1393 orthopaedic surgeon members of the Australian Orthopaedic Association. Results: 217 surgeons completed the survey, yielding a response rate of 16%. 88% of responders were either very satisfied or moderately satisfied with their jobs. 20% of responders were dissatisfied with their hours of work and a further 15% of responders were dissatisfied with the level of recognition they get for good work. Surgeons with higher job satisfaction were less likely to feel that workload severely compromised their personal/family life (p<0.001), had better perceived self-health (p=0.04), and were less likely to have considered leaving orthopaedic surgery in the last year (p<0.001).Discussion: Australian orthopaedic surgeons are highly satisfied with their jobs. There may be a role for active interventions aimed at improving hours of work and work-life balance.

▼ The purpose of this study was to evaluate the use of one-third tubular plates for the treatment of benign defects in the medial distal metaphysis of the femur. Benign cysts are a common occurrence in long bones, and are of concern in load-bearing bones, such as the tibia and femur. These space-occupying growths are removed by curettage of the affected region. Numerous post-curettage management options have been described in the literature, which generally include filling the defect with either synthetic or biological materials. Unfortunately, complications, such as infectious disease transmission, thermal injury, and a robust inflammatory have all been reported in the literature. In response to these concerns, a number of studies reported successful healing of benign cortical defects in long bones with no augmentation after curettage, however, the lack of structural support results in an increased risk of fracture through the defect site. Therefore, it is advantageous to investigate a treatment option that adds structural support to the defect site and permits the use of osteoconductive and osteoinductive materials within the bone cavity. The purpose of this thesis was threefold: First, a quasi-static experimental comparison of intact and cortical defect specimens was conducted to determine the structural consequences incurred by the introduction of a 15 mm cortical defect under isolated axial and torsional loads. Second, an experimental combined axial/torsional fatigue analysis was employed to further analyze the behavior of the defect specimens, and to determine the structural stiffness regained by the addition of a one-third tubular plate. Third, a numerical approach was used to consider the structural consequences of varying sized defects under isolated and combined quasi-static axial and torsional loading, and to further analyze the results of adding the plate to the defect specimens. This study revealed that a one-third tubular plate might be a clinically viable option for structural support of small cortical defects in the distal femur. Furthermore, the loss in stiffness by the defect is exacerbated under combined axial/torsional loading. This is a more physiologically relevant loading mode and may provide more clinically useful results.

▼ The clinical management of critical sized defects and traumatic bone injuries continues to challenge the orthopaedic field. The gold standard of treatment uses autologous bone grafting to promote repair. While effective in many cases, donor site morbidity is a common complication. The field of bone tissue engineering aims to develop viable alternatives to autologous bone graft. The bone graft substitute INFUSE® (bone morphogenetic protein-2 [BMP-2] in acellular collagen sponge) is currently in clinical use, however we and others have hypothesized that the collagen delivery system is suboptimal.
This thesis aims to develop high viscosity sugar-based carriers as alternative delivery systems for BMP-2. Initial studies utilise sucrose acetate isobutyrate (SAIB), already in clinical trials for drug delivery. Rodent implantation and fracture models were used to compare SAIB for BMP-2 delivery as well as other adjunctive agents. SAIB/BMP-2 was also trialled in a pig model of hip osteonecrosis. Novel sugar-based carriers were developed using polycondensation and esterification and tested for biocompatibility and in vivo BMP-2 delivery. These studies represent an innovative approach to bone tissue engineering with multiple clinical applications.

▼ Anteromedial Gonarthrosis (AMG) is a distinct phenotype of knee osteoarthritis (OA), with a specific pattern of disease on the tibia. There is full thickness cartilage loss anteromedially, progressing to an area of damaged cartilage, and then to an area of macroscopically and histologically normal cartilage posteriorly. This reproducible pattern of disease can be considered to be a spatial model of OA progression and provides an alternative and less biologically varied set of specimens than the commonly used multiple joint compartments in which to quantify disease-related changes. The aim of this thesis was to explore in detail spatial and quantitative differences in cell, matrix and molecular features between areas of cartilage in AMG. A real time PCR study was undertaken comparing damaged and undamaged cartilage in AMG. Previous work from our research group had shown increased type I collagen content of undamaged cartilage in AMG. This gene expression study corroborated this finding by demonstrating increased COL1A1 expression in undamaged cartilage, compared to damaged cartilage. MMP1, MMP3, MMP13 and ADAMTS4 were also shown to have increased expression in undamaged cartilage. Since these changes arise in tissue before any macroscopic damage is apparent, these may indicate early changes of the cartilage matrix in AMG. In order to confirm that these changes are directly related to the damage process and not only to normal regional variations, Above Knee Amputations were collected from patients with peripheral vascular disease but no overt OA and a template of the AMG joint surface created to allow for matched regional sampling. Studies into their histology, immunoassays and qPCR were performed in order to compare results with those from AMG specimens. Histology demonstrated low scores throughout but allowed for a division into lower (macroscopically and histologically normal) and higher grade (surface wear/possible early signs of OA) groups. Immunoassays showed elevated type I collagen in high grade but not low grade groups in the posterior cartilage. No differences in mRNA expression were detected using qPCR suggesting that changes seen in AMG specimens were specific to the OA disease process. Because the causes of cell death in OA are not fully understood an immunohistochemical study into apoptosis was performed. TUNEL staining demonstrated higher levels of apoptosis, the more damaged the cartilage. The presence of Active Caspase 3, Cytochrome C, Active Bax and Bim with the same distributions demonstrated apoptosis occurring via the intrinsic or mitochondrial pathway. The high levels of 3-Nitrotyosine in more damaged cartilage implicated reactive oxygen species in apoptotic mechanisms. A microarray study was conducted comparing regions of damaged and undamaged cartilage in AMG. 389 genes were found to be significantly differentially expressed between regions. Several pathways rich in gene expression changes were highlighted including cellular development, inflammatory response and skeletal disorders. Results…
