Aims and objectives. Our aim was to evaluate the indications for patients undergoing magnetic resonance imaging (MRI) of the knee prior to referral to an orthopaedic specialist, and ascertain whether these scans altered initial management. Materials and Method. We retrospectively reviewed all referrals received by a single specialist knee surgeon over a 1-year period. Patient demographics, relevant history, examination findings and past surgical procedures were documented. Patients having undergone MRI prior to referral were identified and indications for the scans recorded. These were reviewed against The NHS guidelines for Primary Care Physicians to identify if the imaging performed was appropriate in each case. Results. A total of 261 patients were referred between 1. st. July 2018 and 30. th. June 2019. 87/261 patients underwent MRI of the knee joint prior to referral. The mean patient age was 53 years with predominance of male patients (52 verses 35 females). 21/87 patients (24%) underwent the appropriate imaging prior to referral with only 13% of patients undergoing x-ray imaging before their MRI. In cases where MRI was not indicated, patients waited an average of 12 weeks between their scan and a referral being sent to the specialist knee surgeon. Conclusion. 76% of patients referred to orthopaedics had inappropriate MRI imaging arranged by their primary care physician. For a single consultant's referrals over 1 year these unnecessary MRI scans cost the NHS £13,200. Closer adherence to the guidelines by primary care physicians would result in a financial saving for the NHS, faster referral times and a more effective use of NHS resources

Abstract. Objectives. Magnetic resonance imaging (MRI) is one of the most widely used investigations for knee pain as it provides detailed assessment of the bone and soft tissues. The aim of this study was to report the frequency of each diagnosis identified on MRI scans of the knee and explore the relationship between MRI results and onward treatment. Methods. Consecutive MRI reports from a large NHS trust performed in 2017 were included in this study. The hospital electronic system was consulted to identify whether a patient underwent x-ray prior to the MRI, attended an outpatient appointment or underwent surgery. Results. 4466 MRI knees were performed in 2017 with 71.2% requested in primary care and 28.1% requested in secondary care. The most common diagnosis was signs of arthritis (55.2%), followed by meniscal tears (42.8%) and ACL tears (8.3%). 49.4% of patients who had an MRI attended outpatients and 15.6% underwent surgery. The rate of knee surgery was significantly higher for patients who had their scans requested in secondary care (32.9% vs 8.9%, p < 0.001). Conclusion. The rate of surgical intervention following MRI is low and given these results it seems unlikely that the scan changes practice in most cases. The rate of surgery and outpatient follow up was significantly higher in scans requested by secondary care. We urge clinicians avoid wasteful use of MRI and recommend the use of plain radiography prior to MRI where arthritis may be present

Around 1% of the 185,000 primary hip and knee arthroplasties performed in the UK are followed by prosthetic joint infection (PJI). Although PJI affects a small percentage of patients, it is one of the most devastating complications associated with this procedure. Treatment usually involves further major surgery which can adversely affect patients' quality of life. Understanding current service provision provides valuable information needed to design and evaluate support interventions for patients. The aim of this survey was to identify usual care pathways and support in UK NHS orthopaedic centres for this population. The 20 highestvolume UK NHS orthopaedic centresfor hip and knee arthroplasty account for 33–50% of all cases treated for prosthetic joint infection. Infection leads at each centre were invited to participate in a survey about usual care provision and support for PJI. Questions exploredfollow up time-points; use of standard outcome measures; multidisciplinary care plans; supportive in-patient care and care after treatment; and onward referrals. Survey responses were recorded on a standardised proforma. Data were entered into Excel for analysis, then reviewed and coded into categories and frequency statistics to describe categorical data. A descriptive summary was developed based on these categories. Eleven of the highestvolume orthopaedic centres completed the survey. Follow-up of patients varied greatly across centres; some centres reviewed patients at weekly or 2 week intervals, while all centres saw patients at 6 weeks. Long-term follow-up varied across centres from 3–4 monthsto 12 monthly. Length of follow-up period varied from until the infection had cleared toindefinitely. Follow-up timepoints were only standardised in 4 out of 11 centres. Only 1 centre had a dedicated infection clinic. Advice on who patients should contact if they had concerns included the consultant, community nurse, extended scope practitioner or the ward, while 3 centres told patients to avoid calling their GP. Only half of the centres routinely used standardised outcome measures with patients with PJI. The majority of centres provided standard physiotherapy and occupational therapy (OT) to in-patients while approximately half also offered social support. Only one centre provided dedicated physiotherapy and OT on a separate infection ward. Three centres provided hospital at home or community services to patients in-between operative stages. Only 3 out of 11 centres stated they had specific multidisciplinary care plans in place for patients. Once discharged most patients were provided with physiotherapy, OT and social services if needed. Common barriersto referral included complexities of referring patients outside the hospital catchment area;lack of availability of community services, and shortage of staff including physiotherapists. Delays in rehab and social services could also be problematic. Findings show wide variation intreatment pathways and support for patients treated for PJI, both as inpatients and in the community. Only one of the 11 centreswho participated had a dedicated infection clinic. Only one centre suggested they individualised their physiotherapy support. A number of barriers exist to referring patients on to other support services after revision surgery

Introduction

In 2011 the Scottish Government published national MRSA screening requirements. A comparison of Orthopaedic and ENT elective surgery intended to juxtapose a specialty known to take MRSA screening seriously with one that has little clinical concern with regards MRSA infection. ENT surgery parallels Orthopaedics in using implants and there potentially being MRSA colonisation at or close to the site of surgery. In Orthopaedics MRSA infection is infrequent, but implant infection with antibiotic resistant bacteria has a particularly poor prognosis. In ENT MRSA infection is rare and colonisation does not influence patient care.

Aims

An evaluation of MRSA screening practice for elective Orthopaedics and ENT surgery at Gartnavel General Hospital with regards strategy and implementation.

Abstract. INTRODUCTION. In the NHS the structure of a “regular healthcare team” is no longer the case. The NHS is facing a workforce crisis where cross-covering of ward-based health professionals is at an all-time high, this includes nurses, doctors, therapists, pharmacists and clerks. Comprehensive post-operative care documentation is essential to maintain patient safety, reduce information clarification requests, delays in rehabilitation, treatment, and investigations. The value of complete surgical registry data is emerging, and in the UK this has recently become mandated, but the completeness of post-operative care documentation is not held to the same importance, and at present there is no published standard. This project summarises a 4-stage approach, including 6 audit cycles, >400 reviewed operation notes, over a 5 year period. OBJECTIVE. To deliver a sustainable change in post operative care documentation practices through quality improvement frameworks. METHODS. Stage 1: Characterise the problem and increase engagement through: SMART aims, process mapping, hybrid action-effect and driver diagram and stakeholder analysis. Multi disciplinary stakeholders were involved in achieving a consensus of evidence-based auditable criteria. Stage 2: Baseline audit to assess current practice. Stage 3: Intervention planning by stakeholders. Stage 4: Longitudinal monitoring through run charts and iterative refinement. RESULTS. Stage 1: Process mapping identified numerous downstream effects of the absence of critical information from operation notes, and the action-effect diagram highlighted the multiple unnecessary mitigating actions performed by ward staff. An MDT consensus was achieved on 15 essential criteria for complete documentation, including important negative fields. Interest-influence matrix identified stakeholder groups with high influence but low interest who needed engagement to deliver change. Stage 2: Baseline audit demonstrated unexpectedly poor documentation: >75% compliance in 4 criteria, and <50% compliance in 10 criteria, which elevated the interest of key stakeholders. Stage 3: A post-operative care template based on the 15 criteria was embedded within the existing IT software. It allowed use of existing operative templates, with a non-overwriting suffix requiring only two mouse clicks. Stage 4: Re-audit at 3 and 12 months showed improved and sustained compliance. At 24 months compliance had declined. Questionnaire of template usage identified problems of criteria response options, and lack of awareness of template by newly appointed staff. Template update improved compliance over the next 6 months (>75% compliance in 11 criteria). Finally, a further reaudit conducted 12 months after the template update (5 years post baseline audit) showed a sustained improvement in compliance (>75% compliance in 13 criteria). CONCLUSIONS. Simple innovation through quality improvement frameworks has changed documentation practices by 1) achieving a consensus from stakeholders, 2) a “shock and awe” moment to highlight existing poor documentation and increase engagement 3) implementing change which fit easily into existing systems, 4) respecting autonomy rather than enforcing change and 5) longitudinal monitoring using run charts and an iterative process to ensure the template remains fit for purpose. This model has now successfully been translated to other subspecialities within the orthopaedic department. Declaration of Interest.

The aim is to investigate if there is a relation between patellar height and knee flexion angle. For this purpose we retrospectively evaluated the radiographs of 500 knees presented for a variety of reasons. We measure knee flexion angle using a computer-generated goniometer. Patellar height was determined using computer generated measurement for the selected ratios, namely, the Insall–Salvati (I/S), Caton–Deschamps (C/D) and Blackburne–Peel (B/P) indices and Modified I/S Ratio. A search of an NHS hospital database was made to identify the knee x rays for patients who were below the age of forty. A senior knee surgeon (DC) supervised three trainee trauma and orthopaedics doctors (HA, JM, ES) working on this research. Measurements were made on the Insall–Salvati (I/S), Caton–Deschamps (C/D) and Blackburne–Peel (B/P) indices and Modified I/S Ratio. The team leader then categorised the experimental measurement of patients’ knee flexion angle into three groups. This categorisation was according to the extent of knee flexion. The angles were specifically, 10.1 to 20, 20.1 to 30, and 30.1 to 40 degrees of knee flexion. Out of the five-hundred at the start of the investigation, four hundred and eighteen patients were excluded because they had had either an operation on the knee or traumatic fracture that was treated conservatively

Open lower limb fractures are resource-intensive fractures, accounting for a significant proportion of the workload and cost of orthopaedic trauma units. A recent study has evaluated that the median cost of direct inpatient treatment of open lower-limb fractures in the National Health Service (NHS) is steep, at £19189 per patient. Healthcare providers are expected to be aware of the costs of treatments, although there is very limited dissemination of this information, neither on a national or local level. Older adults (>65 years old) are at an increased risk of the types of high-energy injuries that can result in open lower limb fractures. Generally, there remains a significant lack of literature surrounding the cost of open fracture management, especially in specific patient groups that are disproportionately affected by these fractures. This study has calculated the direct inpatient care costs of older adults with open lower limb fractures. Open lower limb fractures in adult patients over 65 years old treated at Addenbrooke's Hospital of Cambridge University Hospitals NHS Trust were identified over the period of March 2014-March 2019. Isolated fractures of the femur, tibia and fibula over this time period were included. Direct inpatient care costs were calculated using information about the sustained fracture, operative time, implant(s) and theatre kit(s) used, the number of patient bed-days on the orthopaedic ward and critical care unit, and the number of hours of inpatient physiotherapy received. Direct inpatient care costs were compared with the income received by our centre for each of these cases, according to Healthcare Resource Group (HRG) cost codes. Our data was also compared with existing literature on Patient Level Costing (PLC) figures for open lower limb fractures. We extracted data from 58 patients over the age of 65 years treated for open isolated lower limb fractures at Addenbrooke's Hospital, Cambridge University Hospitals NHS Trust, between March 2014 and March 2019. The median cost of inpatient care calculated in this study was £20,398 per patient, resulting in a financial loss to the hospital of £5113 per patient. When the results were disaggregated by sex, the median cost for an open lower limb fracture in a male patient was £20,886 compared to £19,304 in a female patient. Data were also disaggregated by the site of injury, which produced a median cost for an open femur fracture of £23,949, and £24,549 and £15,362 for open tibia and ankle fractures, respectively. The absence of published primary literature and clinical audits on this topic continues to hinder the inclusion of cost-effectiveness as an important factor in clinical decision-making. This study provides valuable insight into the true cost of open lower limb fractures in a key patient population in a Major Trauma Centre in England and highlights the large losses incurred by hospitals in treating these cases. These results support the revision of the remuneration structures in the NHS for the treatment of elderly patients with these injuries

Since the emergence of the COVID-19 pandemic, the NHS has been under unprecedentedpressure. Elective surgery had ceased, and trauma surgery has decreased dramatically. Surgical training is multi-faceted and requires a specialist trainee to have a timetable which includes regular elective non-emergency operating, trauma operating and training in outpatient clinics. Consequently, training in theatre and the achievement of operative numbers and index procedures had not been possible for Trauma and Orthopaedic (T&O) specialist trainees. The Joint Committee on Surgical Training (JCST) has clear training index requirements for all T&O specialist trainees. In this study, we surveyed specialist trainees in the North West London deanery against the annual requirements set by the JCST guidelines. In addition, we retrospectively assessed the total number of trauma referrals and operations scheduled in our unit during the COVID-19 outbreak compared to that one year previously. The aim of this study is to objectively assess the effect the pandemic has on T&O specialist training. A total of 24 responses were collected from specialist trainees. The results of the survey showed 87% of trainees believed that their training had been affected. 75% of trainees felt they were not on track to meet operative numbers for the year, and 71% felt index number achievement had been affected. Trauma case numbers dropped by 20% compared to that one year previously. We recommend timely, planned and conscientious remediation for specialist trainees’ educational requirements. Specialist trainees must take responsibility for their training and use of additional educational opportunities. Clinical supervisors and training programme directors must provide additional support and guidance to achieve ARCP outcomes however in some scenarios extension of training may be necessary

C. Difficile infections in elderly patients with hip fractures is associated with high morbidity and mortality. Antibiotic regimens with penicillin and its derivatives is a leading cause. Antibiotic prophylactic preferences vary across different hospitals within NHS. We compared two antibiotic prophylactic regimens - Cefuroxime only prophylaxis and Teicoplanin with Gentamicin prophylaxis in fracture neck of femur surgery, and evaluated the incidence of C. Difficile diarrhea and Surgical Site Infection (SSI). To assess the Surgical Site Infection and C. Difficile infection rate associated with different regimens of antibiotics prophylaxis in fracture neck of femur surgery. Data was analyzed retrospectively. Neck of femur fracture patients treated surgically from 2009 in our unit were included. Age, gender, co morbidities, type of fracture, operation, ASA grade was collected. 1242 patients received Cefuroxime only prophylaxis between January 2009 and December 2012 (Group 1) and 486 patients received Teicoplanin with Gentamicin between October 2015 and March 2017 (Group 2). There were 353 males and 889 female patients in Group 1 and 138 males and 348 female patients in Group 2. The co morbidities in both groups were comparable. Incidence of C. Difficile diarrhea and Surgical Site Infection (SSI) was noted. Statistical analysis with chi square test was performed to determine the ‘p’ value. C. Diff diarrhea rate in Group 2 was 0.41 % as compared to 1.29 % in Group 1. The Surgical Site Infection (SSI) rate in Group 2 was 0.41 % as compared to 3.06 % in Group 1. The comparative results were statistically significant (p = 0.0009). Prophylactic antibiotic regimen of Teicoplanin with Gentamicin showed significant reduction in C. Difficile diarrhea & Surgical Site Infection in fracture neck of femur patients undergoing surgery

Conventional proximal tibial osteotomy is a widely successful joint-preserving treatment for osteoarthritis; however, conventional procedures do not adequately control the posterior tibial slope (PTS). Alterations to PTS can affect knee instability, ligament tensioning, knee kinematics, muscle and joint contact forces as well as range of motion. This study primarily aimed to provide a comprehensive investigation of the variables influencing PTS during high tibial osteotomy using a 3D surgical simulation approach. Secondly, it aimed to provide a simple means of implementing the findings in future 3D pre-operative planning and /or clinically. The influence of two key variables: the gap opening angle and the hinge axis orientation on PTS was investigated using three independent approaches: (1) 3D computational simulation using CAD software to perform virtual osteotomy surgery and simulate the post-operative outcome. (2) Derivation of a closed-form mathematical solution using a generalised vector rotation approach (3) Clinical assessment of synthetically generated x-rays of osteoarthritis patients (n=28; REC reference: 17/HRA/0033, RD&E NHS, UK) for comparison against the theoretical/computational approaches. The results from the computational and analytical assessments agreed precisely. For three different opening angles (6°, 9° and 12°) and 7 different hinge axis orientations (from −30° to 30°), the results obtained were identical. A simple analytical solution for the change in PTS, ΔP. s,. based on the hinge axis angle, α, and the osteotomy opening angle, θ, was derived:. ΔP. s. =sin. -1. (sin α sin θ). The clinical assessment demonstrated that the absolute values of PTS, and changes resulting from various osteotomies, matched the results from the two relative prediction methods. This study has demonstrated that PTS is impacted by the hinge axis angle and the extent of the osteotomy opening angle and provided computational evidence and analytical formula for general use

Knee pain is common, representing a significant socioeconomic burden. Caused by a variety of pathologies, its evaluation in primary-care is challenging. Subsequently, an over-reliance on magnetic resonance imaging (MRI) exists. Prior to orthopaedic surgeon referral, many patients receive no, or incorrect, imaging. Electronic-triage (e-triage) tools represent an innovative solution to address this problem. The primary aim of this study was to ascertain whether an e-triage tool is capable of outperforming existing clinical pathways to determine the correct pre-hospital imaging based on knee pain diagnosis. Patients ≥18 years with a new presentation of knee pain were retrospectively identified. The timing and appropriateness of imaging was assessed. A symptom-based e-triage tool was developed, using the Amazon LEXbotplatform, and piloted to predict five common knee pathologies and suggest appropriate imaging. 1462 patients were identified. 17% of arthroplasty patients received an ‘unnecessary MRI’, whilst 28% of arthroscopy patients did not have a ‘necessary MRI’, thus requiring a follow-up appointment, with a mean delay of three months (SD 2.6, range 0.2-20.2). Using NHS tariffs, a wasted cost through unnecessary/necessary MRIs and subsequent follow-up appointments was estimated at £45,816. The e-triage pilot was trialled with 41 patients (mean age:58.4 years, 58.5% female). Preliminary diagnoses were available for 34 patients. Using the highest proportion of reported symptoms in the corresponding group, the e-triage tool correctly identified three of the four knee pathologies. The e-triage tool did not correctly identify anterior cruciate ligament injuries (n=3). 79.2% of participants would use the tool again. A significant number of knee pathology patients received incorrect imaging prior to their initial hospital appointment, incurring delays and unnecessary costs. A symptom-based e-triage tool was developed, with promising pilot data and user feedback. With refinement, this tool has the potential to improve wait-times and referral quality, whilst reducing costs

Abstract. Introduction. Skeletal muscle wasting is an important clinical issue following acute traumatic injury, and can delay recovery and cause permanent functional disability particularly in the elderly. However, the fundamental mechanisms involved in trauma-induced muscle wasting remain poorly defined and therapeutic interventions are limited. Objectives. To characterise local and systemic mediators of skeletal muscle wasting in elderly patients following acute trauma. Methods. Experiments were approved by a local NHS Research Ethics Committee and all participants provided written informed consent. Vastus lateralis biopsies and serum samples were taken from human male and female patients shortly after acute trauma injury in lower limbs (n=6; mean age 78.7±4.4 y) and compared to age-matched controls (n=6; mean age 72.6±6.3 y). Atrogenes and upstream regulators (MuRF1; MAFbx; IL6, TNFα, PGC-1α) mRNA expression was assessed in muscle samples via RT-qPCR. Serum profiling of inflammatory markers (e.g. IL6, TNFα, IL1β) was further performed via multiplex assays. To determine whether systemic factors induced by trauma directly affect muscle phenotype, differentiated primary human myotubes were treated in vitro with serum from controls or trauma patients (pooled; n=3 each) in the final 24 hours of differentiation. Cells were then fixed, stained for myogenin and imaged to determine minimum ferret diameter. Statistical significance was determined at P<0.05. Results. There was an increase in skeletal muscle mRNA expression for E3 ligase MAFbx and inflammatory cytokine IL-6 (4.6 and 21.5-fold respectively; P<0.05) in trauma patients compared to controls. Expression of myogenic determination factor MyoD and regulator of mitochondrial biogenesis PGC-1α was lower in muscle of trauma patients vs controls (0.5 and 0.39-fold respectively; P<0.05). In serum, trauma patients showed increased concentrations of circulating pro-inflammatory cytokines IL-6 (14.5 vs. 0.3 pg/ml; P<0.05) and IL-16 (182.7 vs. 85.2 pg/ml; P<0.05) compared to controls. Primary myotube experiments revealed serum from trauma patients induced atrophy (32% decrease in diameter) compared to control serum-treated cells (P<0.001). Conclusion. Skeletal muscle from patients following acute trauma injury showed greater expression of atrophy and inflammatory markers. Trauma patient serum exhibited higher circulating pro-inflammatory cytokine concentrations. Primary human myotubes treated with serum from trauma patients showed significant atrophy compared to healthy serum-treated controls. We speculate a mechanism(s) acting via circulating factors may contribute to skeletal muscle pathology following acute trauma. Declaration of Interest.

Abstract. Objective. Meta-analysis of clinical trials highlights that non-operative management of degenerative knee meniscal tears is as effective as surgical management. Surgical guidelines though support arthroscopic partial meniscectomy which remains common in NHS practice. Physiotherapists are playing an increasing role in triage of such patients though it is unclear how this influences clinical management and patient outcomes. Methods. A 1-year cohort (July 2019–June 2020) of patients presenting with MRI confirmed degenerative meniscal tears to a regional orthopaedic referral centre (3× ESP physiotherapists) was identified. Initial clinical management was obtained from medical records alongside subsequent secondary care management and routinely collected outcome scores in the following 2-years. Management options included referral for surgery, conservative (steroid injection and rehabilitation), and no active treatment. Outcome scores collected at 1- and 2-years included the Forgotten Joint Score-12 (FJS-12) questionnaire and 0–10 numerical rating scales for worst and average pain. Treatment allocation is presented as absolute and proportional figures. Change in outcomes across the cohort was evaluated with repeated measures ANOVA, with Bonferroni correction for multiple testing, and post-hoc Tukey pair-wise comparisons. As treatment decision is discrete, no direct contrast is made between outcomes of differing interventions but additional explorative outcome change over time evaluated by group. Significance was accepted at p=0.05 and effect size as per Cohen's values. Results. 81 patients, 50 (61.7%) male, mean age 46.5 years (SD13.13) presented in the study timeframe. 32 (40.3%) received conservative management and 49 (59.7%) were listed for surgery. Six (18.8%) of the 32 underwent subsequent surgery and nine of the 49 (18.4%) patients switched from planned surgery to receiving non-operative care. Two post-operative complications were noted, one cerebrovascular accident and one deep vein thrombosis. The cohort improved over the course of 2-years in all outcome measures with improved mean FJS-12 (34.36 points), mean worst pain (3.74 points) average pain (2.42 points) scores. Overall change (all patients) was statistically significant for all outcomes (p<0.001), with sequential year-on-year change also significant (p<0.001). Effect size of these changes were large with all Cohen-d values over 1. Controlling for age and BMI, males reported superior change in FJS-12 (p=0.04) but worse pain outcomes (p<0.03). Further explorative analysis highlighted positive outcomes across all surgical, conservative and no active treatment groups (p<0.05). The 15 (18%) patients that switched between surgical and non-surgical management also reported positive outcome scores (p<0.05). Conclusion(s). In a regional specialist physiotherapy-led soft tissue knee clinic around 60% of degenerative meniscal tears assessed were referred for surgery. Over 2-years, surgical, non-operative and no treatment management approaches in this cohort all resulted in clinical improvement suggesting that no single strategy is effective in directly treating the meniscal pathology, and that perhaps none do. Clinical intervention rather is directed at individual symptom management based on clinical preferences. Declaration of Interest.

Abstract. Background. Tibiotalocalcaneal (TTC) fusion is indicated for severe arthritis, failed ankle arthroplasty, avascular necrosis of talus and as a salvage after failed ankle fixation. Patients in our study had complex deformities with 25 ankles having valgus deformities (range 50–8 degrees mean 27 degrees). 12 had varus deformities (range 50–10 degrees mean 26 degrees) 5 ankles an accurate measurement was not possible on retrospective images. 10 out of 42 procedures were done after failed previous surgeries and 8 out of 42 had talus AVN. Methods. Retrospective case series of patients with hindfoot nails performed in our centre identified using NHS codes. Total of 41 patients with 42 nails identified with mean age of 64 years. Time to union noted from X-rays and any complications noted from the follow-up letters. Patients contacted via telephone to complete MOXFQ and VAS scores and asked if they would recommend the procedure to patients suffering similar conditions. 17 patients unable to fill scores (5 deceased, 4 nails removed, 2 cognitive impairment and 6 uncontactable). Results. In our cohort 33/38 of hindfoot nails achieved both subtalar and ankle fusion in a mean time of 7 months. 25 patients with 26 nails had mean follow up with post op scores of 4 years. Their Mean MOXFQ scores were (Pain: 12.8 Walking: 12 Social: 8) and visual analogue pain score was 3. 85% of patients wound recommend this surgery for a similar condition. 20 complications with 15 requiring surgery(5 screw removals, 1 percutaneous drilling, 1 fusion site injection, 8 nail revisions). Conclusion. In our experience hindfoot nail TTC fusion reliably improves the function of patients with severe symptoms in a variety of pathophysiological conditions and complex deformities. Most of our patients would recommend this procedure. There is a lack of studies with long-term follow-up

Abstract. Objectives. 1. To investigate the effect of revision total knee replacement (TKR) on gait kinematics in patients with a primary TKR and instability.2. To compare gait kinematics between patients with a well-functioning TKR and those with a primary TKR and symptoms of instability. Methods. This single-centre observational study is following patients who have had a revision TKR due to knee instability. Data was collected pre- and post-operatively at 8–12 week follow-up. The data was compared to a control group of 18 well-functioning TKR patients. Kinematic gait data was collected during routine clinics using a treadmill-based infrared 3D system (Vicon, Oxford, UK) and a published lower limb marker-set. Patients performed 15 strides at three different speeds: 0.6mph, self-selected, and a ‘slow walk’ normalised to leg length (Froude number 0.09). PROMs questionnaires were collected. NHS ethical approval was obtained. Results. Data was collected for 18 well-functioning TKR patients and 8 revision TKR patients pre- and post-operatively, but only 5 could walk at the normalised speed. When walking at a normalised speed (Froude 0.09), patients with a TKR with instability had reduced range of knee flexion (52° (sd 14)) compared to those with a well-functioning TKR (59° (sd 11)). Short term follow-up after a revision TKR operation demonstrated a stiffer knee (45° (sd 12)). However, those with revision TKR had a more flexed knee during stance phase. Conclusions. At short-term follow-up, this cohort of revision TKR patients appear to have reduced flexion range, while remaining more flexed during stance. This may represent a less efficient gait pattern, which may also adversely affect the implant[1]. Longer term follow-up may demonstrate whether this normalises with post-operative rehabilitation.

Abstract. Objectives. The purpose of this study was to determine the cost of inpatient admissions for developmental dysplasia of the hip (DDH) at a UK tertiary referral centre, and identify any association between newborn screening (NIPE) status and the cost of treatment. Methods. This was a retrospective study, using hospital episodes data from a single NHS trust. All inpatient episodes between 01/01/2014 to 30/06/2019 with an ICD-10 code stem of Q65 ‘congenital deformities of hip’ were screened to identify admissions for management of DDH. Data was subsequently obtained from electronic and paper records. Newborn screening status was recorded, and patients were divided into ‘NIPE-positive’ (diagnosed through selective screening) and ‘NIPE-negative’ (not diagnosed through screening). Children with neuromuscular conditions or concomitant musculoskeletal disease were excluded. The tariff paid for each inpatient episode was identified, and the number of individual clinic attendances, surgical procedures and radiological examinations performed (USS, XR, CT, MRI) were recorded. Results. 41 patients with DDH were admitted for inpatient management. 44% (n = 18) were NIPE-positive, diagnosed mean age 6.7 weeks. 56% (n = 23) were NIPE-negative, diagnosed mean age 26 months. The total cost of inpatient care in the NIPE-positive group was £171,471 (£9,526.18 per-patient) compared to £306,615 (£13,331.10 per-patient) for NIPE-negative. In the NIPE-positive group, there were 99 clinic attendances, 47 inpatient admissions and 160 radiological examinations performed (36 USS, 107 XR, 17 CT). This compared to 148 clinic attendances, 59 inpatient admissions and 215 radiological examinations (187 XR, 26 CT, 2 MRI) in the NIPE-negative group. Conclusion. A greater proportion of inpatient admissions for DDH are among NIPE-negative children. They incur a higher cost of treatment per patient and necessitate more inpatient resources. This study adds to the ongoing conversation around the cost-effectiveness of selective screening for DDH in the UK. Declaration of Interest.

Abstract. Objectives. Routine blood test following total shoulder arthroplasty (TSA) cost the NHS more than £72000 in 2018 without definite evidence of their impact on patients’ management or outcomes. This study aimed to ascertain if routine laboratory tests are a necessity post TSA or can be implemented on a per-patient. Methods. A retrospective review of the electronic records completed for 251 patients underwent TSA over 6 years. 193 patients were eligible for analysis. Primary outcomes were interventions to the abnormal postoperative blood tests. Secondary outcomes were the length of stay (LOS), and readmission within 30 days and 90 days. Results. 193 patients underwent 216 TSAs; 72 % were females and 18% males. The mean age was 78 ± 7.2 years. Completed procedures included 134 reverse, 64 anatomical and 18 revision TSAs. 136 patients (63%) had an abnormal postoperative blood test, however, only 8 (3.7%) required intervention. The average postoperative haemoglobin (Hb) drop was 19 g/L with 94 patients (43.5%) having Hb <109g/L. 4 patients (1.8%) dropped Hb < 80g/L; only 2 patients (0.9%) were symptomatic and received RBC transfusion . 6 patients (2.8%) developed acute kidney injury and treated by IV fluids. The mean LOS was 3.2 ± 2.9 days .5 patients (2.3%) were readmitted within 30 days and 6 patients (2.8%) within 90 days. Univariate analysis showed association only between abnormal Creatinine and LOS (p<0.05) and of these patients, all had abnormal preoperative Creatinine baseline. No statistical correlation detected between age (p=0.287), postoperative Hb (p=0.230) and LOS nor readmission at 30 or 90 days. Conclusions. Routine postoperative blood tests are not required as they have not shown to produce a meaningful clinical impact in this cohort of patients nor on the re-admission rate, causing unnecessary costs. We recommend assessing each patient and request for investigations in a coherent and justified manner. Declaration of Interest.

Background. The Arthroplasty Pain Experience (APEX) studies are two randomised controlled trials in primary total hip (THR) and knee replacement (TKR) at a large UK orthopaedics centre. APEX investigated the effect of local anaesthetic wound infiltration (LAI), administered before wound closure, in addition to standard analgesia, on pain severity at 12 months. This abstract reports results of the within-trial economic evaluations. Methods. Cost-effectiveness was assessed from the health and social care payer perspective in relation to quality adjusted life years (QALYs). Resource use was collected from hospital records and patient-completed postal questionnaires, and valued using unit cost estimates from local NHS Trust and national tariffs. Missing data were imputed using chained equations. Costs and outcomes were compared per trial arm and plotted in cost-effectiveness planes. The economic results were bootstrapped incremental net monetary benefit statistics (INMB) and cost-effectiveness acceptability curves. One-way deterministic sensitivity analyses explored any methodological uncertainty. Results. In both trials, LAI was cost-saving and more effective than standard care. Using the £20,000 per QALY threshold, in THR, the INMB was £1,125 (95%BCI, £183 to £2,067) and the probability of being cost-effective was over 98%. In TKR, the INMB was £264 (95%BCI, −£710 to £1,238), with only 62% probability of being cost-effective. Considering an NHS perspective only, LAI was no longer dominant in THR, but still highly cost-effective, with an INMB of £961 (95%BCI, £50 to £1,873). Conclusions. Administering LAI is a cost-effective treatment option in THR and TKR surgeries. The evidence is stronger for THR, because of larger QALY gain. In TKR, there is more uncertainty around the economic result, and smaller QALY gains, but results point to LAI being cheaper than standard analgesia, which includes a femoral nerve block.
