We aimed to analyse the clinical outcomes and survivorship of anatomic total shoulder arthroplasty using a stemless humeral component with cemented pegged polyethylene glenoid performed with the technique of eccentric reaming to partially correct retroversion. These results were then compared with TSA using the same implant for end-stage shoulder arthritis with a normal version of the native glenoid. A retrospective case series was performed using a prospectively collected database of anatomic TSA patients operated at Woodend General Hospital, Aberdeen, UK. Between 2010 and 2019, 107 total shoulder arthroplasties (TSA) were done using standard anatomic stemless TSA implants (Affinis Short, Mathys Ltd, Bettlach, Switzerland) in 98 patients. Standardized preoperative and postoperative shoulder radiological imaging for glenoid retroversion was collected. Depending on the angle of native glenoid version, patients were divided into retroverted and non-retroverted glenoid as per the Walch Classification. To assess the radiological outcome at the final follow-up, radiolucency was assessed on the glenoid and humeral side using the Lazarus grading. The final clinical and radiologic outcome from the retroverted group was compared with the population with a non-retroverted glenoid. Five TSAs were excluded from the analysis as they did not have satisfactory postoperative radiographs. Hence, a total of 102 shoulders were available for analysis.Objective

This randomized controlled study aimed to compare surgical duration, intra-operative blood loss, and fluoroscopy time between the suprapatellar and infrapatellar approaches for intramedullary interlocking nailing of tibia. We included 40 adult patients with tibial shaft fractures, excluding those with non-union, revision surgery, or polytrauma. Patients were divided equally into two groups using block randomization: Group A (20 patients) underwent the infrapatellar approach, and Group B (20 patients) underwent the suprapatellar approach. Blood loss was measured using gravimetric method and by changes in pre-operative and post operative haemoglobin levels. Surgical duration was estimated by calculating the time elapsed between the start and end of the procedure and fluoroscopy time was logged from the fluoroscopy machine. In group A, blood loss averaged 154±30.98ml, slightly more than in group B (150±32.92ml), though the difference was not statistically significant (p>0.05). Group A also showed a higher difference in haemoglobin levels (2.20±1.13 gm/dl) compared to group B (1.15±0.93 gm/dl), which was statistically significant (p=0.02). Fluoroscopy time and surgery duration were slightly longer in group A compared to group B but not statistically significant(p=0.693). The suprapatellar approach results in lesser blood loss, potentially promoting faster recovery, reduced need for blood transfusions and shorter hospital stays. It also entails shorter fluoroscopy time and surgical duration (though not statistically significant) which may reduce radiation exposure for the surgical team.
Our aim to study the incidence, demographics, inpatient stay, use of imaging and outcomes of patients who have non-operatively managed NOF fractures. The data was collected retrospectively for the last 14 years (Jan 2009- Jan 2023) of all non-operatively managed NOF fractures at a level 2 trauma centre. The data was collected from the trauma board, electronic patient records, radiographs, and National Hip Fracture Database (NHFD). The data collected as demographic details, fracture classification, any reasons for non-operative management, mortality and further surgical management was done. Patients who died or transferred to other sites for specialist surgery were excluded.Objectives
Study Design & Methods
Distal humerus fractures in elderly population are often comminuted and presents multiple challenges. When managed with fixation the results are often complicated with stiffness, pain, and reduced function while total elbow replacement is fraught with lifelong restrictions on load bearing which can significantly affect elderly patients who rely assistive devices for ambulation. Elbow hemiarthroplasty however, presents a viable alternative in these cases. This series evaluates the results of the distal humerus hemiarthroplasty in a single centre. Data was collected retrospectively. Comprehensive case reviews were done to collect demographic, intra-operative and post-operative data. Fractures were classified as per AO classification. The primary outcome was functional outcome and range of motion (ROM). The secondary outcomes were complications and patient satisfaction.Objectives

Several studies have reported elevated blood cobalt (Co) and chromium (Cr) concentrations in patients with total knee replacements (TKRs). Up to 44% of tissue samples taken from patients with failed TKRs exhibit histological evidence of metal sensitivity/ALVAL. In simulated conditions, metal particles contribute approximately 12% of total wear debris in TKR. We carried out this investigation to determine the source and quantity of metal release in TKRs. We analysed 225 explanted fixed-bearing TKRs (Attune, Genesis II, NexGen, PFC, and Vanguard) revised for any indication. These were analysed using peer-reviewed [coordinate measuring machine (CMM)] methodology to measure the volumetric wear of the polyethylene (PE) bearing surfaces and trays. The trays were analysed using 2D profilometry (surface roughness-Ra) and light microscopy. Histological and blood metal ion concentration analyses were performed in a sub-sample of patients.Objectives

Instability in ACL deficient knees can lead to medial compartment osteoarthritis. The risk of developing significant OA is 5x higher in knees with ACL deficiency. In associated Varus, there is quicker progression of the medial OA along with a varus thrust exerting strain on the ACL graft. The simultaneous valgus HTO and ACL reconstruction decompresses the medial tibiofemoral joint, corrects the mechanical-axis and reduces strain on the graft. Outcomes for this simultaneous procedure are still unclear in literature and we attempt evaluating its functional outcome. This Panel study was performed using data from 2019 to 2022 on 21 patients who had ACL insufficiency with Varus or medial OA and underwent a simultaneous Opening-wedge HTO with Arthroscopic ACL reconstruction. The mean follow-up was 2 years. The patients were evaluated with IKDC and Lysholm scores, Lachman test and ROM pre and post-operatively. The HKA was compared pre and post-operatively and the complications were evaluated. The progression of OA was evaluated with serial radiographs post-operatively.Introduction

Sacroiliac joint dysfunction is a degenerative condition that can result in low back pain and is likely underdiagnosed. Diagnosis is made clinically with the patient experiencing pain in the sacroiliac joint region. Initial management is non-operative with pain management, physiotherapy, injections, and rhizolysis. If these fail then surgical management, by sacroiliac joint fusion, can be considered. The aim of this study was to review the outcomes of all patients who underwent sacroiliac joint fusion by a single surgeon in a large district general hospital between April 2018 and April 2023. A retrospective review of all patients who underwent sacroiliac joint fusion between April 2018 and April 2023 was conducted. Data was collected from clinical letters, operative notes, and the British Spinal Registry. Oswestry Disability Index (ODI) and Visual Analogue Scale (VAS) for back and leg pain were recorded as well as any post-operative complications.Objectives

During TKR it is mandatory to achieve perfect soft tissue balance and component alignment. It is necessary to access all tight structures for proper releases. We aim to analyze the results of Trivector arthrotomy approach for TKRs. It is a retrospective study of 1050 cases between 2010-2020. All cases were performed by a single surgeon. Approach includes dividing distal 30% of vastus medialis along with medial retinaculum - 1cm medial to patella and patellar tendon distally up to Tibial tuberosity and raised as a single flap.Introduction & Aim
Methods
Unicompartmental knee replacement (UKR) is a conservative option for degenerative disease, with mobile (Oxford UKR) and fixed bearing (Physica ZUK) the most commonly used devices. The primary reasons for revising UKRs include disease progression (36.9%), loosening (31.7%), and pain (7.5%). Loosening typically occurs due to osteolysis caused by wear particles from the polyethylene (PE) inserts. There is limited published literature which has quantified volumetric material loss from the PE inserts of cemented fixed-bearing UKRs. This study aimed to quantify bearing wear and backside deformation of these PE components. At our national retrieval centre, we measured changes volumetric bearing wear and backside deformation of 31 explanted fixed-bearing Physica ZUK UKR PE inserts using a peer-reviewed methodology based on coordinate measuring machine analysis. These explants had been revised for any indication [Females (19) and Males (12)]. The location of the wear scars was identified and mapped. We compared the volumetric wear from the bearing surface with contemporary total knee replacement (TKR) inserts.Objectives

Video recording to teach and assess both technical and non-technical skills is well-established within medical education. Trainees’ clinical and practical competencies are evaluated using Procedure-Based Assessments (PBAs). However, there is limited research describing how these PBAs truly reflect trainee performance. We sought to: assess the duration between the procedure and PBA completion assess the perceived viability of supplementing assessments using intra-operative camera footage and clarify medico-legal considerations for the use of cameras in theatre. We undertook a survey of Orthopaedic trainees in the East of England Deanery, United Kingdom. A six-item questionnaire was designed and provided to trainees (paper and online) to assess the time between procedure and filling in PBA forms, level of consultant input, time to PBA sign-off and trainees’ views on current PBA methods, operative video recording and retrospective access to clinical footage.Introduction

Minimally invasive surgery (MIS) has gained popularity for hallux valgus, compared to the traditional scarf osteotomy (OS). Though evidence suggests similar clinical outcomes, there is paucity of randomised controlled studies. This study aimed to assess the feasibility of conducting a randomised controlled trial comparing the patient recorded and clinical outcomes for the surgical management of Hallux Valgus between OS and MIS Chevron Akin (MICA). Patients suitable for surgical correction were invited to participate. Post-op rehabilitation was standardised for both groups. Patients completed a validated questionnaire (Manchester Oxford Foot questionnaire and EQ-5D-5L) pre-operatively and post-operatively at 6 months and 1 year. Radiological parameters and range of motion were measured pre-and post-operatively.Objectives

Neurological injuries are most common complication, which has refrained many surgeons from opting elbow arthroscopy for indicated surgeries. The objective of this study was to evaluate the safety of anterolateral (AL) and posterolateral (PL) portals and chances of injury to the radial nerve and posterior interosseous nerve around the elbow joint during elbow arthroscopy. A cadaveric study was conducted on 16 non dissected cadavers (32 elbow specimens) between the period of January 2021 to June 2022. Four portals were established using 4 mm Steinmann pins which are Proximal AL Portal, Mid-AL Portal, Distal AL Portal and PL Portal. The measurements of each portal were taken for each nerve and compared with each other.Objective

The use of All-Poly Tibia has been in practice since the early 1970's. Recently due to the reports on wear and osteolysis in other articulations, this component has generated significant interest. In the current study we aim to report early medium-term results of All-poly Tibial components in elderly (>70 years) patients. Study of 455 cases done between 2005-2020. All the cases were performed by a single surgeon. All-Poly Tibial component implantations were performed using Standard mechanical jigs and the same posterior-stabilized implant was used for all cases.Introduction & Aim

We identified an unusual pattern of backside deformation on polyethylene (PE) inserts of contemporary total knee replacements (TKRs). The PE backside's margins were inferiorly deformed in TKRs with NexGen central-locking trays. This backside deformation was significantly associated with tray debonding. Furthermore, recent studies have shown high rate of tray debonding in PS NexGen TKRs. Subsequently, a field safety notice was issued regarding the performance of this particular device combination and the Option tray has been withdrawn from use. Therefore, we hypothesised that the backside deformation of PS inserts may be greater than that of CR inserts. At our national implant retrieval centre, we used peer-reviewed techniques to analyse changes in the bearing wear rate and backside surface deformation of NexGen PE inserts using coordinate measuring machines [N=84 (CR-43 and PS-41) TKRs with non-augmented-trays]. Multiple regression was used to determine which variable had the greatest influence on backside deformation. The amount of cement cover on trays was quantified as a %of the total surface using Image-J software.Objectives

Acetabular fractures with quadrilateral plate involvement have been shown to have a high rate of complications. Anatomic suprapectineal plating systems have been developed to manage these injuries with good short-term outcomes, however long-term maintenance of anatomical reduction and functional outcomes is yet to be established. Efficacy of maintenance of reduction and functional outcomes at a minimum of 5-years follow-up is the aim of this study. A retrospective cohort study examining patients aged over 16 years following fixation of acetabular fractures with quadrilateral plate involvement at a trauma centre in the United Kingdom. All patients had acetabular fracture fixation with an anatomically designed suprapectineal plate. Patients were admitted from March 2014 to January 2017. Primary outcomes included objective radiological outcomes such as reduction quality, maintenance of reduction, metalwork failure, complications (such as reoperation, neurological deficit and mortality) and subjective patient-related outcome measures (PROMs) using the Oxford Hip Score and EuroQol EQ5D Score at a minimum of 5-years post-operatively.Objectives

The rise in the adoption of outpatient arthroplasty has been attributed to its cost-effectiveness, although safety concerns persist. In this meta-analysis, we compare inpatient and outpatient joint arthroplasty with a primary focus on readmission and complication rates, using exclusively high-quality prospective data. Cost-effectiveness was used as a secondary outcome measure. A literature search was performed in Medline, Embase and Cochrane Library from inception to October 2023. A predefined strategy was used to conduct a systematic review and meta-analysis. Twelve studies were deemed eligible for inclusion. These were critically appraised using RoB analysis and MINORS criteria. Overall readmission rate, readmission rate for THA, readmission rate for TKA, complication rate and cost-analysis were selected as outcomes of interest. Forest plots were extracted using RevMan 5.3.5 software.Background

Systematic reviews of randomized controlled trials (RCTs) are the highest level of evidence used to inform patient care. However, it has been suggested that the quality of randomization in RCTs in orthopaedic surgery may be low. This study aims to describe the quality of randomization in trials included in systematic reviews in orthopaedic surgery. Systematic reviews of RCTs testing orthopaedic procedures published in 2022 were extracted from PubMed, Embase, and the Cochrane Library. A random sample of 100 systematic reviews was selected, and all included RCTs were retrieved. To be eligible for inclusion, systematic reviews must have tested an orthopaedic procedure as the primary intervention, included at least one study identified as a RCT, been published in 2022 in English, and included human clinical trials. The Cochrane Risk of Bias-2 Tool was used to assess random sequence generation as ‘adequate’, ‘inadequate’, or ‘no information’; we then calculated the proportion of trials in each category. We also collected data to test the association between these categories and characteristics of the RCTs and systematic reviews.Aims

Orthopedic implants play a tremendous role in fixing bone damages due to aging as well as fractures. However, these implants tend to get colonized by bacteria on the surface, leading to infections and subsequently prevention of healing and osteointegration. Recently, Roupie et al. showed that a nisin layer-by-layer based coating applied on biomaterials has both osteogenic and antibacterial properties. The Prior to the implantation procedure, Aim
