Introduction. The knee is the most commonly injured joint in sporting accidents, leading to substantial disability, time off work and morbidity (1). Treatment and assessment vary around the UK (2), whilst there remains a limited number of high-quality randomised controlled trials assessing first time, acute soft tissue knee injuries (3,4). As the clinical and financial burden rises (5), vital answers are required to improve prevention, diagnosis, treatment, rehabilitation, and delivery of care. In association with the James Lind Alliance, this BASK, BOSTAA and BOA supported prioritising exercise was undertaken over a year. Methods. The James Lind Alliance methodology was followed; a modified nominal group technique was used in the final workshop. An initial survey invited patients and healthcare professionals to submit their uncertainties regarding soft tissue knee injury prevention, diagnosis, treatment, rehabilitation, and delivery of care. Seventy-four questions were formulated to encompass common concerns. These were checked against best available evidence. Following the interim survey, 27 questions were taken forward to the final workshop in January 2023, where they were discussed, ranked, and scored in multiple rounds of prioritisation by groups of healthcare professionals, patients, and carers. Results. Over 1000 questions were submitted initially. Twenty-seven were taken forward to the final workshop following the surveys. Nearly half of the responses were from patients/carers. The Top 10 (Figure 1) includes prevention, diagnosis, treatment, and rehabilitation questions, reflecting the concerns of patients, carers, and a wider multidisciplinary team. Conclusion. This validated process has generated an important, wide- ranging Top 10 priorities for future soft tissue knee injury research. These have been submitted to the National Institute for Health and Care Research and are now available for researchers to investigate. The final 27 questions which were taken to the final workshop have also been published on the James Lind Alliance website. Research into these questions will lead to future high-quality research, thus improving patient care & outcomes. For any figures or tables, please contact authors directly

Introduction. Activity scales are used throughout orthopaedics as a component of PROMs. Tegner Activity Scale is commonly used and is validated in various knee injuries in adults. It has a reading age of 18 years presenting an understanding problem for children. An alternative is HSS-PediFABS, but this looks at specific skills like running, cutting, pivoting rather than sporting level. Our aim was to determine if children understood TAS and whether their answers compared to how their parents scored them and determine if our suggested sporting levels were more appropriate for them. Method. We created a study form to compare levels given by children and their parent. We added our own suggested levels, with a reading age of 9, created by a discussion group of paediatric orthopaedic surgeons. Following ethics approval, a sample size was determined via power calculation. All patients over 7 and their parents presenting to the orthopaedic clinic at SCH over a 4-month period were asked to fill out the TAS, baseline questions and rank the new suggested sporting levels. Results. 51 patients and their parents were recruited, with a mean age of 13 (±0.31, 8–17). 35% female. The mean TAS score for children rating themselves was 7.04 (±0.32, 2–10) vs 6.43 (±0.37, 0–10) for parents rating the child (p=0.31). The average weekly activity time rated by children was 6.72 hours (±0.84, 0–30) vs 7.48 (±1.02, 0–36) rated by the parent (p=0.68). Our suggested levels for paediatric patients were ordered correctly by both groups (mode score). The mean new activity level for children was 4.9 (±0.24, 2–9) vs 4.81 (±0.26, 1–8) by their parent(p=0.79). The mean score difference for TAS was 1.42 vs 1.2 in the new score (p=0.38). Conclusion. Paediatric patients had difficulty understanding the TAS and there was poor agreement of activity levels between patients and parents

Introduction. Anterior cruciate ligament (ACL) injuries are one of the most common knee injuries amongst elite athletes and usually require an ACL reconstruction (ACLR) to enable return to sport. Secondary surgery can result in a longer rehabilitation period and often a. significant time away from sport which can have implications to the athlete including contract obligations and sponsorship. Advances in ACLR techniques and meniscal repair techniques as well as an awareness of meniscal root lesions, ramp lesions and lateral extraarticular procedures (LEAPs) during ACL surgery has improved outcomes. The purpose of this study was to evaluate the rates of secondary surgery following the introduction of a systematic arthroscopic evaluation of the knee, improved meniscal repair techniques and the addition of a concomitant LEAP This systematic approach was introduced after October 2012 (10/2012). Methods. Professional athletes who underwent primary ACLR with a minimum follow-up of 2 years were identified from the (blinded for review). Those who had undergone major concomitant procedures such as multi-ligament reconstruction or osteotomy were excluded. Analysis of the database and review of medical records identified athletes who had underwent secondary surgery procedures. Results. A total of 342 athletes with a mean follow-up of 100.2 +/− 51.9 months (range, 24–215 months) were analysed. 130 athletes underwent surgery before 10/2012 and 212 athletes underwent surgery after 10/2012. Overall, 74 patients (21.6%) underwent secondary surgery. 39 patients (30.0% including 13.1% for graft rupture) before 10/2012 and 35 patients (16.5% including 6.6% for graft rupture) after 10/2012. A multivariate analysis was performed using the Cox model and demonstrated that athletes undergoing ACLR before10/2012 were at almost 2-fold risk of secondary surgery (hazard ratio (HR), 1.768(1.103;2.836), p=0.0256) when compared with those undergoing ACLR after 10/2012. (Figure 1). Conclusion. Professional athletes undergoing ACLR with a systematic arthroscopic evaluation with the use of advanced meniscal repair techniques and the combination with a LEAP result in a significantly lower rate of secondary surgery.

The aim of this study was to determine if patient reported outcome scores for arthroscopic meniscectomy are adversely affected by the degree of knee osteoarthritis or patient body mass index (BMI). All patients who underwent arthroscopic meniscectomy within the NHS in Scotland between 6th February and 29th April 2012 were audited as part of the Scottish Government Musculoskeletal Knee Arthroscopy Audit and were eligible for inclusion within this study. A total of 270 patients returned both their pre-operative and post-operative EuroQol 5Q5D5L descriptive questionnaire and Knee injury and Osteoarthritis Outcomes Scores. Patients were stratified according to BMI, degree of osteoarthritis, history of injury, and duration of knee symptoms. Pre-operative to post-operative EuroQol index scores [0.642±0.253 to 0.735±0.277, median±SD] and Knee injury and Osteoarthrtis Outcome Scores [44.63±18.78 to 62.28±24.94, median±SD] improved across all patients (p<0.0001). This was irrespective of degree of BMI, history of injury, or duration of symptoms. There was no such improvement in patients with moderate to severe osteoarthritis. Those patients with a BMI >35 kg/m2 had lower post-operative scores than the pre-operative scores of those of BMI <30 kg/m2. Arthroscopic meniscectomy is beneficial regardless of patient BMI, duration of symptoms, history of injury, or in the presence of mild arthritis

Purpose. Tibia plateau fractures are severe knee injuries which have a great impact on the patients' lives, but in what extend is not clear yet in the literature. The purpose of this study was to investigate the gait alternations after treatment of patients who had severe tibia plateau fractures which were treated with circular ilizarov frame. Materials & Methods. We have evaluated the gait pattern of patients who were treated with circular Ilizarov frame after severe tibia plateau fractures (Schatzker IV-VI) in our department. The gait was tested by using a force plate in a walking platform. Ground Reaction Forces (GRF) data were collected during level walking at self-selected speeds. The patients performed two walking tasks for each limb and the collected data were averaged for each limb. Demographic, clinical, radiological and quality of life questionnaire (SF-12) data were also collected. Results. We have analysed the gait through the GRF of fifteen patients (aged 50.8 ±17.3 years), who had undergone treatment with circular Ilizarov frame following severe tibia plateau fractures (Schatzker IV-VI). Nine were male and six were female. The tests were performed at an average of 13.2 months after the initial treatment. SF-12 Mental scores have returned to normal (mean 54.6 ±12.3) but physical scores remained impaired (mean 40.6 ±10.8). A one-way repeated measures ANOVA was conducted to compare the GRFs and gait timing data of the affected limb with the normal one. Single limb support interval was significantly reduced to the affected limb (p=0.001) and terminal stance phase was prolonged for the normal limb (p=0.035). During this phase of the gait circle the knee is on its maximum flexion and the quadriceps contracts to bring the femur above the tibia. It seems that these patients during the gait circle reduce the flexion of their affected knee to make their single stance shorter. To the normal limb the patients manage to reduce more the GRFs during the mid-stance phase (F2 force), this difference do not reach significance, but illuminates the tendency of reduced knee flexion in that phase. The rest of the GRF and gait timing data did not had significant differences. Conclusions. One year after severe tibia plateau fracture treated with circular ilizarov frame the patients manage to return to almost normal gait pattern. Reduce single limb stance and terminal stance phase to the affected knee can be explained by the tendency of not flexing their deficient knee as much during that gait phase

Alpine ski sports changed rapidly in the last decade. Complex fractures of the proximal tibia, typically seen in high energy trauma, has been seen more frequently and more often related to alpine skiing. The aim of our study was to identify reasons for proximal tibia fracture in alpine skiing and observe the outcome. All patients with proximal tibia fractures related to alpine skiing, which were treated in our two trauma centers were included. The patients received a questionnaire at the emergency department, dealing with accident details and the skiing habits. The fractures were classified according to the AO fracture classification scheme. The follow up was performed at least one year after trauma with the Lysholm, the Tegner activity, as well as the WOMAC VAS Score. Between 2007 and 2010 a total of 188 patients with proximal tibia fractures caused by alpine skiing were treated. 43 patients had a type A, 96 patients a type B and 49 a type C injury. The incidence was increasing over the period continuously. The main trauma mechanism was an accident without a third party involvement with an increased rotational and axial compression impact. All outcome scores were related to fracture severity with significant worse results for the type C fractures. In conclusion, proximal tibia fractures are an increasing and serious injury during alpine skiing. Further technical progress in skiing material should focus on these knee injuries in future

Introduction. Stiffness of the knee after total knee arthroplasty (TKA) impairs knee function and reduces patient satisfaction. Limited preoperative range of motion (ROM) and a diagnosis of osteoarthritis seem to be associated with postoperative stiffness, and medical comorbidities such as diabetes mellitus have been discussed as predisposing factors. The present study was undertaken in order to analyse both patient-related and surgical factors that could be associated with the need for mobilization under anaesthesia (MUA) after TKA. Methods. We designed a case-control-study and extracted the study population from our local arthroplasty register. We identified all patients in our register that required MUA following primary TKA (n=35) and then randomly selected 4 control patients for each case of MUA. Incomplete medical records resulted in the exclusion of 18 patients, leaving 157 patients. Univariate analysis was used in order to investigate differences between the two groups with respect to demographics, pre- and postoperative ROM, medical or psychiatric comorbidities, and the type of implant. Variables with a proposed influence on outcome were entered into a binary logistic regression model, and risk ratios (RR) were calculated with 95% confidence intervals (CI). Results. Regression analysis showed that age at operation, the presence of chronic obstructive lung disease (COLD), and preoperative flexion significantly affected outcome: Increasing age decreased the risk for needing MUA with a RR of 0.88 (CI 0.82–0.94, p<0.001) per year. Patients with COLD had significantly higher risk of needing MUA with a RR of 9.82 (CI 1.84–52.3, p=0.007). Impaired preoperative flexion was an important predictor of postoperative stiffness with a RR of 0.97 (CI 0.95–0.99, p=0.027), implicating that the risk for MUA decreased by approximately 3% for each additional degree of flexion. Gender, BMI, cardiovascular comorbidity, the presence of rheumatoid arthritis, diabetes mellitus, previous knee injury, and the type of implant did not significantly affect the risk for MUA. In univariate analysis, patients requiring MUA had significantly lower knee flexion at discharge than control patients (78° vs. 61°, p<0.001). Interpretation. We conclude that the presence of COLD, impaired preoperative knee flexion, and younger age increase the risk for needing MUA after primary TKA. The finding that COLD increases the risk for MUA is novel: It is known that patients with COLD have higher systemic levels of inflammatory mediators, and we are tempted to speculate that postoperative arthrofibrosis could be a result of enhanced systemic inflammatory activity. In our hands, the choice of implant and comorbidities other than COLD were not associated with an increased risk for MUA

Aims

The aim of this study was to compare the cost-effectiveness of treatment with an osseointegrated percutaneous (OI-) prosthesis and a socket-suspended (S-) prosthesis for patients with a transfemoral amputation.

Patients and Methods

A Markov model was developed to estimate the medical costs and changes in quality-adjusted life-years (QALYs) attributable to treatment of unilateral transfemoral amputation over a projected period of 20 years from a healthcare perspective. Data were collected alongside a prospective clinical study of 51 patients followed for two years.

Aims

Fracture clinics are often characterised by the referral of large numbers of unselected patients with minor injuries not requiring investigation or intervention, long waiting times and recurrent unnecessary reviews. Our experience had been of an unsustainable system and we implemented a ‘Trauma Triage Clinic’ (TTC) in order to rationalise and regulate access to our fracture service. The British Orthopaedic Association’s guidelines have required a prospective evaluation of this change of practice, and we report our experience and results.

Patients and Methods

We review the management of all 12 069 patients referred to our service in the calendar year 2014, with a minimum of one year follow-up during the calendar year 2015.

Coronal plane fractures of the posterior femoral condyle, also known as Hoffa fractures, are rare. Lateral fractures are three times more common than medial fractures, although the reason for this is not clear. The exact mechanism of injury is likely to be a vertical shear force on the posterior femoral condyle with varying degrees of knee flexion. These fractures are commonly associated with high-energy trauma and are a diagnostic and surgical challenge. Hoffa fractures are often associated with inter- or supracondylar distal femoral fractures and CT scans are useful in delineating the coronal shear component, which can easily be missed. There are few recommendations in the literature regarding the surgical approach and methods of fixation that may be used for this injury. Non-operative treatment has been associated with poor outcomes. The goals of treatment are anatomical reduction of the articular surface with rigid, stable fixation to allow early mobilisation in order to restore function. A surgical approach that allows access to the posterior aspect of the femoral condyle is described and the use of postero-anterior lag screws with or without an additional buttress plate for fixation of these difficult fractures.
