Abstract. Objectives. ACL graft-suture fixation can be constructed with needle or needleless techniques. Needleless techniques have advantages of decreased injury, preparation time and cost. The Nice Knot (NK) is common among upper extremity procedures; however, its efficacy in ACL reconstruction relative to other needleless methods is not well known. The purpose of this study was to biomechanically compare quadriceps tendon (QT) grafts prepared with the NK versus the modified Prusik Knot (PK). Methods. Twenty QT grafts were harvested from 10 embalmed human cadaver specimens. 10 were prepared with the PK and 10 with the NK using a No.2 FiberWire (Arthrex, Naples, FL). The prepared grafts were then mounted in a materials testing machine (ElectroPuls E10000, Instron, Norwood, MA) and subjected to tensile loading based on an established protocol. Each tendon-suture specimen was preconditioned with 3 cycles of 0–100N at 1Hz followed by a constant load of 50N for 1 minute and cyclic loading of 200 cycles from 50–200N at 1Hz and then loaded to failure at a displacement rate of 20mm/min. Load and displacement data for each tendon-suture construct was recorded by the testing machine. Results. The average age of the donors was 89.1 ± 8.6 years. The NK showed significantly smaller elongations after pre-tensioning (p < 0.01), preloading (p < 0.001), and cyclic loading (p < 0.001). Peak load was greater for the PK than the NK (p = 0.047). No significant differences were seen for stiffness (p = 0.41) or cross-sectional area (p = 0.22). Conclusions. The results of this biomechanical study show that the NK constructs provide less elongation than the PK constructs but with similar stiffness. The NK offers an alternative option for needleless ACL graft preparation technique. Declaration of Interest.

Between 2016–2019, 4 patients developed hip infections post-hemiarthroplasty. However, between 2020–2021 (Covid-19 pandemic period), 6 patients developed hip infections following hip hemiarthroplasty. The purpose of the investigation is to establish the root causes and key learning from the incident and use the information contained within this report to reduce the likelihood of a similar incident in the future. 65 patients presented with a neck of femur fracture during Covid-19 pandemic period between 2020–2021, 26 had hip hemiarthroplasty of which 6 developed hip infections. Medical records, anaesthetic charts and post-hip infections guidelines from RCS and NICE were utilised. Proteus, Enterococci and Strep. epidermis were identified as the main organisms present causing the hip infection. The average number of ward moves was 4 with 90% of patients developing COVID-19 during their hospital stay. The chance of post-operative wound infection were multifactorial. Having had 5 of 6 patients growing enterococci may suggest contamination of wound either due to potential suboptimal hygiene measures, inadequate wound management /dressing, potential environmental contamination if the organisms (Vancomycin resistant enterococci) are found to be of same types and potential hospital acquired infection due to inadequate infection control measures or suboptimal hand hygiene practices. 3 of the 5 patients grew Proteus, which points towards suboptimal hygiene practices by patients or poor infection control practices by staff. Lack of maintenance of sterility in post op wound dressings alongside inexperience of the handling of post-operative wound in non-surgical wards; multiple ward transfers exceeding the recommended number according to trust guidelines especially due to pandemic isolation measures and COVID-19 infection itself had resulted in an increased rate of hip infections during the COVID-19 pandemic. Multidisciplinary team education and planned categorisation and isolation strategy is essential to minimise the rate of further hip infections during the pandemic period in future

Introduction and Objective. The most common paediatric orthopaedic injury requiring hospital admission is a femoral fracture. There is debate regarding the optimal surgical technique for fixing femoral diaphyseal fractures in children aged 4 to 12 years. The National Institute for Health and Care Excellence (NICE) and the American Academy of Orthopaedic Surgeons (AAOS) have issued relevant guidelines, however, there is limited evidence to support these. The aim of this study was to conduct a systematic review and meta-analysis to compare the complication rate following flexible intramedullary nailing (FIN), plate fixation and external fixation (EF) for traumatic femoral diaphyseal fractures in children aged 4 to 12. Materials and Methods. We searched MEDLINE, EMBASE and CENTRAL databases for interventional and observational studies. Two independent reviewers screened, assessed quality and extracted data from the identified studies. The primary outcome was the risk of any complication. Secondary outcomes assessed the risk of pre-specified individual complications. Results. Nine randomised controlled trials (RCTs) and 19 observational studies (six prospective and 13 retrospective) fulfilled the eligibility criteria. Within the RCTs, five analysed FIN (n=161), two analysed plates (n=51) and five analysed EF (n=168). Within the observational studies, 13 analysed FIN (n=610), seven analysed plates (n=214) and six analysed EF (n=153). The overall risk of complications was lower following plate fixation when compared to FIN fixation (RR 0.45, 95% CI 0.28 to 0.73, p=0.001) in the observational studies. The overall risk of complications was higher following EF when compared to FIN fixation in both RCTs (RR 1.94, 95% CI 1.25 to 3.01, p=0.003) and observational studies (RR 1.97, 95% CI 1.50 to 2.58, p<0.001). The overall risk of complications was higher following EF when compared to plate fixation in both RCTs (RR 7.42, 95% CI 1.84 to 29.98, p=0.005) and observational studies (RR 4.39, 95% CI 2.64 to 7.30, p<0.001). Conclusions. Although NICE and the AAOS recommend FIN for femoral diaphyseal fractures in children aged 4 to 12, this study reports a significantly decreased relative risk of complications when these injuries are managed with plates. Our findings provide valuable information to healthcare professionals who are involved in discussing the risk and benefits of different management options with patients and their families. The overall quality of evidence is low, highlighting the need for a rigorous prospective multicentre randomised trial at low risk of bias due to randomisation and outcome measurement to identify if any fixation technique is superior

Abstract. Objectives. Review the evidence of low intensity pulsed ultrasound (LIPUS) for fracture non-union treatment and the potential to treat fractures in patients with co-morbidities at risk of fracture non-union. Methods. Data was gathered from both animal and human studies of fracture repair to provide an overview of the LIPUS in bone healing applications to provide in-depth evidence to substantiate the use in treatment of non-union fractures and to propose a scientific rational to develop a clinical development programme. Results. LIPUS is an effective method for treating fracture non-union, with most studies showing heal rates in the mid 80%. In the UK NICE has published MTG-12 guidance for non-union treatment, which demonstrates that LIPUS is an effective and cost effective method as an alternative to surgery to treat non-union fractures. Basic science studies and evaluation of clinical trial data has led to the understanding that LIPUS can mitigate co-morbidities related to failure of bone healing such as diabetes, advancing age and tobacco use. Future clinical trials will evaluate the use of LIPUS in acute fractures in patients with high risk of low bone healing capacity to prevent the development of a non-union. As with all medical treatments, LIPUS for fracture repair needs to be used appropriately, with poorly fixed fractures or large fracture gaps, being unsuitable for LIPUS treatment. In addition, considerations such as targeting the fracture site in deep-seated bones and clinician / patient engagement to ensure good compliant usage are vital factors to ensure good clinical outcomes. Conclusion. Using basic science research, a thorough knowledge of the mechanism of action has been established, which has elucidated that co-morbidities related to the development of fracture non-union can be mitigated by the LIPUS technology. A pragmatic clinical trial in the United States is currently ongoing to test these hypothesises clinically. Declaration of Interest.

Abstract. Objectives. Our study evaluates financial impact to the Best Practice Tariff (BPT) of hip fracture patients on Novel Oral Anti-Coagulant (NOAC) medication. Since their approval by NICE for the prevention of stroke and systemic embolism in non-valvular atrial fibrillation, the incidence of hip fracture patients admitted to hospitals on NOAC medication (e.g. rivaroxiban, apixaban) has been increasing. BPT for hip fractures has two components: a base tariff and a conditional top-up tariff of £1,335 per patient (applied to patients of 60 years of age). For the top-up tariff, six criteria must be met, of which time-to-surgery within 36 hours is one. Our department currently recommends withholding NOAC medication and delaying surgery for at least 48 hours as per our Trust's haematology guidelines to reduce intra-operative bleeding risk. Therefore, the conditional top-up tariff cannot be claimed for these patients. Method. A retrospective review of our Trust hip fracture patients over 60 years of age admitted during 2019 on NOAC medication using National Hip Fracture Database (NHFD). Results. 545 hip fracture patients had operative treatment at our Trust during the one-year period of 2019. 31 of these patients were admitted on NOAC medication, and therefore had to stop the NOAC and wait for at least 48 hours before having surgery. This translates to a potential hip fracture BPT loss of £41,385 in 2019, as the conditional top-up tariff could not be claimed. Conclusion. This study illustrates the large financial impact to BPT that hip fracture patients admitted on NOAC medications has at our Trust. It raises the argument as to whether the BPT should allow for an increased length of time until surgery for such patients, to allow safe surgical treatment with reduced bleeding risk.

Background. Post-operative acute kidney injury is significant complication following surgery. Patients who develop AKI have an increased risk for progression into chronic kidney disease, end-stage renal failure and increased mortality risk. The patient outcomes following total knee replacement (TKR), who develop AKI has been a topic of interest in recent years as it may have patient and medicolegal implications. Nevertheless, there are no studies looking at the incidence, risk factors and outcomes of AKI following bilateral TKRs at the same sitting. Objectives. To determine the incidence, risk factors and outcomes of post-operative AKI following bilateral TKRs surgery at the same sitting. Methods. This was a retrospective single-centre study performed at the Princess Royal Hospital, which performed a total of 25 BTKR. The incidence, Surgical and patient risk factors were recorded and analysed. Results. The incidence of AKI as defined by NICE guidelines following bilateral TKRs was 20%. 16% (4 patients) had stage 1 and 4% (1 patient) had stage 2 AKI. The mean change in Creatinine between pre- and post-operative blood tests was +19μmol/L. There was a strong significant correlation between CKD and AKI (r=0.75, P<0.05). Furthermore, a moderate correlation was found between higher BMI and pre-operative Charlson index and AKI. AKI did not have an effect on the length of inpatient stay with the mean inpatient length of stay for patients who had an AKI of 10 days compared to 11days for those who did not. All AKIs were resolved within 72 hours. There were no associated mortalities with AKI. Conclusion. The incidence of AKI following bilateral TKR was 20%. Pre-operative chronic kidney disease as well as having a higher BMI were identified as risk factors for developing AKI. Pre-operative CKD optimisation and careful adequate hydration intra-operatively should be considered in these patients. AKI was not associated with an increased length of stay or mortality in our study

Background. Patients who undergo elective hip and knee arthroplasty often have multiple risk factors increasing their likelihood of suffering from hyponatraemia post operatively. Consequently suffering from hyponatraemia post elective hip and knee arthroplasty is common. Consequently we wanted to assess the occurrence of hyponatraemia in our elective arthroplasty unit, assess our effectiveness in managing this and importantly assess how its occurrence impacted on length of patient stay. Method. Retrospective analysis of elective hip and knee arthroplasty patients over a five month period. Pre-operative and post-operative sodium levels analysed and their grade measured using NICE reference ranges. In post-operative hyponatraemic patients blood results were analysed up until discharge. Discharge summaries were reviewed to assess communication between primary and secondary care. Length of admission calculated. Formal action plan developed in partnership with the anaesthetic department to improve future management. Results. 103 patients assessed. 24 (23%) suffered from post-operative hyponatraemia. 11 (48%) were discharged with a normalised sodium. 7 (29%) had documentation regarding their hyponatraemia in the discharge summary. 101 (98%) had a sodium drop post-operatively and 2 patients were hyponatraemic pre-operatively. Average length of stay for hyponatraemic hip patients was 5.00 days compared to 4.20 days for patients with normal sodium levels. Hyponatraemic post op knee patients had an average in hospital stay of 5.09 days compared to 4.13 days in knee patients with a normal post-operative sodium level. Conclusion. Hyponatraemia is common in the post-operative arthroplasty patient. In our unit it led to an increase in length of hospital stay. We believe the introduction of a structured post-operative oral rehydration regime with isotonic fluid would be a simple method to reduce occurrence post operatively. We feel standardising intra-operative fluid prescribing will reduce the likelihood of pushing patients into a post-operative hyponatraemic state. Finally we have introduced a hyponatraemia management flowchart to the department so ward based doctors can recognise and effectively manage hyponatraemic patients. If these measures are implemented length of stay in hospital can potentially be reduced

Introduction. Guidelines from the North American Spine Society (2009 and 2013) are the best evidence-based instructions on venous thromboembolism (VTE) and antibiotic prophylaxis in spinal surgery. NICE guidelines exist for VTE prophylaxis but do not specifically address spinal surgery. In addition, the ruling of the UK Supreme Court in 2015 resulted in new guidance on consent being published by the Royal College of Surgeons of England (RCSEng). This study assesses our compliance in antibiotic, VTE prophylaxis and consent in spinal surgery against both US and UK standards. Methods. Retrospective review of spinal operations performed between August and December 2016. Case notes, consent forms and operation notes were analysed for consent, peri-operative antibiotic prescribing and post-operative VTE instructions. Results. Four Spinal surgeons performed 45 operations during this period. 31 patients (69%) received a copy of the signed consent with this process being formally documented in 22 (71%) of those cases. All patients were consented by a competent surgeon. 82% of cases consented prior to the date of procedure were countersigned on the day of operation. There was a mean time of 25.3 days between initial consent and operation (Range: 0–170). 37 (82%) cases had clear instructions for VTE and antibiotic prophylaxis. All prescribed post-operative antibiotics were administered. Discussion. The North American Guidelines state that prophylactic antibiotic is appropriate in all spinal surgery with prolonged cases requiring intraoperative re-dosing and only complex cases needing a postoperative regimen. Eight patients underwent a complex procedure and 7 appropriately received postoperative antibiotics. Of the 29 patients that underwent a simple procedure, 12 did not receive post-operative regimen, in line with the guidelines. However, the remainder 17 were over treated. The US Guidelines recommend mechanical VTE prophylaxis only in elective spinal surgery except in high risk patients. All our patients received VTE mechanical prophylaxis. RCSEng guidelines require consent being taken prior to procedure by a competent surgeon and confirmed on day of procedure. All patients in our cohort were consented prior to the date of operation allowing time for considering options and independent research. 82% of patients had consent confirmed on day of operation. Conclusion. This study demonstrates that we met guideline advice for all patients with regards VTE prophylaxis. We have a tendency to over treat with post-operative antibiotics and not all patients had their consent confirmed on day of procedure but was consented well before day of operation. North America still lead the way with guidelines on spinal surgery to which we should adhere, with NICE guidelines providing limited instructions. New consenting guidelines from RCSEng may not be currently widely known and thus should be a source of education for all surgeons

One reason why NICE (National Institute for Clinical Excellence) does not support operations by the NHS to heal hyaline cartilage lesions using a patients own cells is because there is no clear evidence to show that these operations are beneficial and cost-effective in the long term. Specifically, NICE identified a deficiency of high quality cartilage being produced in repaired joints. The presence of high quality cartilage is linked to long-lasting and functional repair of cartilage. The benchmark for quality, NICE stipulate, is repair cartilage that is stiff and strong and looks similar to the normal tissue surrounding it, i.e. mature hyaline articular cartilage. Biopsy material from autologous cartilage implantation surgical procedures has the appearance of immature articular cartilage and is frequently a mixture of hyaline and fibrocartilage. Osteoarthritic cartilage, in its early stages, also exhibits characteristics of immature articular cartilage in that it expresses proteins found in embryonic and foetal developmental stages, and is highly cellular as evidenced through the presence of chondrocyte clusters. Therefore, an ability to modulate the phenotype and the structure of the extracellular matrix of articular cartilage could positively affect the course of repair and regeneration of articular cartilage lesions. In order to do this, the biochemical stimuli that induce the transition of an essentially unstructured amorphous cartilage mass (immature articular cartilage) to one that is highly structured and ordered, and biomechanically adapted to its particular function (mature articular cartilage) has to be identified. We show for the first time, that fibroblast growth factor-2 and transforming growth factor beta-1 induce precocious maturation of immature articular cartilage. Our data demonstrates that it is possible to significantly enhance maturation of cartilage tissue using growth factor stimulation; consequently this may have applications in transplantation therapy, or through phenotypic modulation of osteoarthritic chondrocytes in diseased cartilage in order to stimulate growth and maturation of repair tissue


Background. In 2009, the National Institute for Health and Clinical Excellence (NICE) produced the guidance: Low back pain: early management of persistent non-specific low back pain aimed at general practitioners (GPs), consultants, and manual therapists in order to ensure all involved in the care of this complex and often debilitating condition are aware of the options most likely to yield a positive outcome. Two years since the publication of the clinical guidance, services have had ample time to adapt and overcome early teething issues in order to deliver these guidelines. Methods. A retrospective audit was carried out at an out-patient physiotherapy department. One-hundred notes were randomly selected from those who meet the NICE criteria, i.e. non-specific low back pain for six weeks to 12 months in duration. A questionnaire was developed to target National Health Service (NHS) musculoskeletal physiotherapists using electronic media, mail shot and professional networking (clinical interest) groups within the Chartered Society of Physiotherapy (CSP). Sixty-one completed questionnaires were returned detailing the barriers for implementation. The results show that 75% of patients received NICE recommended care, and they improved by numerical rating scale (NRS) −3.89, while those who did not, improved by NRS −1.24 producing a significant difference of 2.654 (95% Confidence Interval 1.008–4.300), p≤0.002. The main perceived barriers were too few follow-up slots, local policy, managerial demands, and inadequate training. Conclusions. The conclusions are that while three-quarters of patients are receiving and benefiting from NICE recommended care, many practitioners feel departmental policy and procedures reduce compliance.

Venous Thromboembolism (VTE) prophylaxis is an essential part of orthopaedic surgeries in preventing life-threatening thromboembolic events such as Deep Vein Thrombosis (DVT) and Pulmonary Embolism (PE). Orthopaedic surgery has the highest incidence rate of thromboembolic events as compared to any other surgical specialities, making it an essential component in managing any orthopaedic case. At Queen's Medical Centre (QMC), a major trauma centre in the United Kingdom (UK), sees up to 750 NOF fracture cases annually, making it one of the busiest trauma and orthopaedic centres in the UK. Our study aims to evaluate how VTE Prophylaxis is conducted in a UK Major Trauma Centre for NOF and pelvic fragility fractures and how human factors can improve its efficacy. The Nottingham University Hospitals (NUH) Trust has implemented new guidelines from August 2019 that patients with fragility fractures such as NOF and pelvic fractures are prescribed with 28 days VTE prophylaxis with Enoxaparin, or their own anti-coagulants if risk of thrombosis exceed the risk of bleeding. This is an adaptation from the trust to align their guidelines closer to the NICE 2018 guidelines. We will be evaluating the initial compliance of VTE Prophylaxis, identify and utilise human factors, then re-analyse the department after implementing interventions on the same batch of junior doctors working in the department. Data of 100 patients with fragility fractures were collected, 50 consecutive patients in the pre-intervention window during August 2019 and 50 in the post-intervention window during November 2019. The pre-intervention data had 43 NOF and 7 Pelvic fractures. Our study showed that 93% of NOF fracture and 100% of pelvic fracture received the correct course of VTE prophylaxis. The data was presented at the local department junior doctor academic session. Three simple human factor interventions were implemented over the course of September and October: Education to the trauma and orthopaedic department on the new guideline, extended VTE labels on drug charts for patients with fragility fractures, VTE reminder labels at doctors' stations. Another 50 consecutive patients' data were collected during November 2019. Data shows that 97.8% of NOF (p>0.05) and 60% of pelvic fracture (p>0.05) received the correct course of VTE prophylaxis. Our data has shown an increase in correct VTE prescription for NOF fracture patients, which is the main bulk of our fragility fracture patients whilst we see a drop in pelvic fracture patients. Due to the limited time frame of four months where junior doctors in the UK rotate between specialities, we are only able to collect data during the first month, implement interventions between datasets and collect data on the final month of the four-month rotation. A future bigger study might provide a more significant result on the department. We believe that the key to achieving 100% VTE prophylaxis in the T&O department is optimising human factors, educating junior doctors, who are not orthopaedic trained, with sufficient information of the guidelines, and evidence of the risk and benefits of providing prolonged VTE prophylaxis for orthopaedic patients. In conclusion, we found that QMC, a major trauma centre with high patient volume and turnover, has a high level of compliance with VTE prophylaxis for fragility fractures and it is imperative that utilising human factors will inch the department closer to its goal of 100% VTE compliance

Robust evidence on the effectiveness of peri-operative local anaesthetic infiltration (LAI) is required before it is incorporated into the pain management regimen for patients receiving total knee replacement (TKR). To assess the effectiveness of peri-operative LAI for pain management in patients receiving TKR we conducted a systematic review, fully powered randomised controlled trial (RCT) and economic evaluation. We searched MEDLINE, Embase and Cochrane databases for RCTs of peri-operative LAI in patients receiving TKR. Two reviewers screened abstracts and extracted data. Outcomes were pain, opioid use, mobilisation, hospital stay and complications. Authors were contacted if required. When feasible, we conducted meta-analysis with studies analysed separately if a femoral nerve block (FNB) was provided. In the APEX RCT, we randomised 316 patients awaiting TKR to standard anaesthesia which included FNB, or to the same regimen with additional peri-operative LAI (60mls 0.25% bupivacaine plus adrenaline). Post-operatively, all patients received patient-controlled morphine. The primary outcome was joint pain severity (WOMAC-Pain) at 12 months. Patients and outcome assessors were blinded to allocation. Within APEX, cost-effectiveness was assessed from the health and social-care perspective in relation to quality adjusted life years (QALYs) and WOMAC-Pain at 12-months. Resource use was collected from hospital records and patient questionnaires. In the systematic review, 23 studies including 1,439 patients were identified. Compared with patients receiving no intervention, LAI reduced WOMAC-Pain by standardised mean difference (SMD) −0.40 (95%CI −0.58, −0.22; p<0.001) at 24 hours at rest and by SMD −0.27 (95%CI −0.50, −0.05; p=0.018) at 48 hours during activity. In three studies there was no difference in pain at any time point between randomised groups where all patients received FNB. Patients receiving LAI spent fewer days in hospital, used less opioids and mobilised earlier. Complications were similar between groups. Few studies reported long-term outcomes. In the APEX RCT, pain levels in hospital were broadly similar between groups. Overall opioid use was similar between groups. Time to mobilisation and discharge were largely dependent on local protocols and did not differ between groups. There were no differences in pain outcomes between groups at 12 months. In the economic evaluation, LAI was marginally associated with lower costs. Using the NICE £20,000 per QALY threshold, the incremental net monetary benefit was £264 (95%CI, −£710, £1,238) and the probability of being cost-effective was 62%. Although LAI appeared to have some benefit for reduced pain in hospital after TKR there was no evidence of pain control additional to that provided by femoral nerve block, however it would be cost-effective at the current NICE thresholds

Articular cartilage injury has a high prevalence in elite and recreational athletes. Articular cartilage repair remains a challenge due to cost effectiveness and clinical effectiveness issues. There are now several effective technologies and it is possible to return to competitive sports following many of the procedures available. The durability of repair tissue is variable and there remains extensive growth in the Scientific world. Evolving cartilage restoration technologies focus on increasing cartilage quality and quantity, while optimising surgery and rehabilitation. In UK ACI has undergone extensive cost effectiveness analysis and the in-depth review has shown that ACI is cost effective compared to microfracture. ACI is indicated for lesions >2cm sq but NICE has considered that it is not indicated for problems after microfracture. This presentation details the various options available to surgeons and examines the cost effectiveness

Background. Prosthetic implants used in primary total hip replacements have a range of bearing surface combinations (metal-on-polyethylene, ceramic-on-polyethylene, ceramic-on-ceramic, metal-on-metal); head sizes (small <36mm, large 36mm+); and fixation techniques (cemented, uncemented, hybrid, reverse hybrid), which influence prosthesis survival, patient quality of life, and healthcare costs. This study compared the lifetime cost-effectiveness of implants to determine the optimal choice for patients of different age and gender profiles. Methods. In an economic decision Markov model, the probability that patients required one or more revision surgeries was estimated from analyses of UK and Swedish hip joint registries, for males and females aged <55, 55–64, 65–74, 75–84, and 85+ years. Implant and healthcare costs were estimated from hospital procurement prices, national tariffs, and the literature. Quality-adjusted life years were calculated using utility estimates, taken from Patient-Reported Outcome Measures data for hip procedures in the UK. Results. Optimal choices varied between traditionally used cemented metal-on-polyethylene and cemented ceramic-on-polyethylene implants. Small head cemented ceramic-on-polyethylene implants were optimal for males and females aged under 65. The optimal choice for adults aged 65 and older was small head cemented metal-on-polyethylene implants. Conclusions. The older the patient, the higher the probability that small head cemented metal-on-polyethylene implants are optimal. Small head cemented ceramic-on-polyethelyne implants are optimal for adults aged under 65. Our findings can influence NICE guidance, clinical practice, and commissioning of services. Funding.

Background. In the adolescent population, operative management of hallux-valgus is controversial. Operations may be less successful than in adults and post-operative recurrence is more common before full skeletal maturity. This study assesses the radiographic, functional and qualitative outcomes of surgical Hallux Valgus correction in adolescents. Methods. Three independent reviewers retrospectively analysed pre and post-operative radiological markers of hallux valgus severity for 44 operations on patients age 13–18. The patient cohort were also asked the Manchester-Oxford foot questionnaire (MOXFQ) to assess functional outcome via telephone interview and patient notes were reviewed for any evidence of complications. Results. There was no evidence of NICE recognised complications from any of the operations performed, however there was persistence or recurrence in 20.8%, requiring a second operation in 10.3%. Radiologically, all operations performed resulted in a reduction in hallux valgus severity. The hallux valgus angle showed a mean reduction of 18.0 degrees (16.3–19.7) and the inter-metatarsal angle by 7.3 degrees (6.55–8.14). 93% of operations resulted in a good MOXFQ outcome score of less than 20 out of a possible 80 negative functional outcome points. This score worsened with age in a statistically significant manner (p=0.03) but had no significant correlation with BMI. Conclusion. Surgical correction of adolescent hallux valgus reduces the radiographic severity, which correlates with good long term outcome. This surgery provides beneficial results to the patient, however there is a high recurrence rate, correlating with younger age and this must be taken into account

Contrary to NICE guidance there remains a role for Austin-Moore hemiarthroplasty (AM) for patients with significant pre-existing comorbidities who are at higher risk of death and complications following cemented hemiarthroplasty. We analysed prospectively-collected data comparing uncemented AM hemiarthroplasty in frail, poorly-mobile patients, and cemented hemiarthroplasty. We analysed age, pre-operative morbidity, duration of operation, death rate and complication rate. AM patients were significantly older with significantly higher ASA grades. It took significantly longer to optimise them before surgery. AM was significantly shorter to perform. There was no significant difference in complications requiring re-operation. Twice as many AM patients developed post-operative pneumonia despite absence of cement. Twice as many AM patients died after surgery and a significant proportion died within the first month despite no increased risk of repeat operation, shorter operating time and no risk of cement-disease. We infer that these patients would likely have fared badly had they undergone a longer, cemented procedure. A modern cemented prosthesis costs £691 more than AM. There exists a subset of patients within the neck of femur cohort who are significantly more unwell. Contrary to guidelines, we suggest that the cheaper, user-friendly Austin-Moore can be a reasonable prosthesis to use for this cohort

More than half of patients with neck of femur (NOF) fractures report their pain as severe to very severe in the first 24hrs. Opioids remain the most commonly used analgesia and are effective for static pain but not dynamic pain. Opioids provide suboptimal analgesia when patients are in a dynamic transition state and their side-effects are a source of morbidity in these patients. The Fascia Iliaca Compartment Block (FICB) involves infiltration of the fascia iliaca compartment with a large volume of low concentrated local anaesthetic to reduce pain by affecting the femoral and lateral cutaneous nerve of the thigh. The London Quality Standards for Fractured neck of femur services (2013) stated that the FICB should be routinely offered to patients. We performed an audit of patient outcomes following the introduction of the FICB across three centres. We performed a two-cycle audit across two hospitals in 2014/15. The first cycle audited compliance with the NICE guidance in the management and documentation of pain and AMTS (Abbreviated Mental Test Scores) in patients. The second cycle was conducted following the integration of the FICB into the multidisciplinary NOF fracture protocol across three hospital sites. Data was collected on numeric pain scores, pre and post-op AMTS and opioid requirements. There were 40 patients audited with 20 in the first cycle prior to the introduction of the FICB and 20 following this. In the second cycle, there was a statistically significant improvement (p<0.001) in the difference between the pre and post-op AMTS. The preliminary findings in this audit support the use of the FICB adjunct to analgesia in the pre-operative management of NOF fracture patients. The FICB is a safe procedure and the organisational learning of this procedure through a multidisciplinary approach can significantly improve the outcomes of NOF fracture patients

Background. Multiple randomised controlled trials have demonstrated that arthroscopy provides little benefit in patients with knee osteoarthritis. In 2008, NICE released guidelines to reflect this evidence. Implementation has been sporadic, and arthroscopy for knee osteoarthritis is commonly performed with an annual incidence of 9.9 per 10,000 in England. Our aim was to establish whether previous arthroscopy affects Patient Reported Outcome Measures (PROMs) in Total Knee Replacement (TKR) patients. Methods. Data was retrospectively collected from 2010–2012 from a University hospital. Pre-operative and one-year post-operative PROMs were collected on patients who had undergone arthroscopy and then TKR, or only TKR. The change in PROMs score over TKR was then compared between groups. Results. Complete data was available for 85 patients: 36 had arthroscopy prior to TKR, with 49 receiving only TKR. There was no difference between the groups with regard to age and gender. Oxford Knee Score (OKS) before TKR for both groups were similar (arthroscopy group 41.9, non-arthroscopy 40.8). At arthroscopy 81% of patients had grade IV arthritis, with 19% demonstrating grade III. Patients who had arthroscopy before TKR had a worse response to TKR compared to those who did not have an arthroscopy (respective mean change of 23.79%, 38.4%, p< 0.001). Conclusions. Although this exploratory study is small and subject to selection bias, our data suggest that arthroscopy may have a detrimental effect on patient function after TKR. This may be due to psychological factors, as there is growing evidence to suggest stress and anxiety negatively affect PROMs4. Medicalisation of patients through arthroscopic procedures may contribute to poor PROMs. This study offers a potential pre-operative factor that may explain some of the variability in outcome seen with TKR. This relationship requires confirmation and exploration in larger studies with correction for confounding factors. Level of evidence. III
