Background. The controversy concerning the benefits of unisegmental cervical disc arthroplasty (CDA) over anterior cervical discectomy and fusion (ACDF) is still open because some randomised clinical trial (RTC) comparing ACDF with CDA have been highly inconclusive. Most of these studies mixed disc prosthesis with dissimilar kinematic characteristics. To date, a compilation of the clinical and radiologic outcomes and adverse events of anterior cervical discectomy and fusion (ACDF) compared with a single cervical disc arthroplasty (CDA) design, the Bryan disc has partially accomplished. Methods. This is a systematic review of
The orthopaedic unit at the Golden Jubilee National Hospital consists of eight consultant orthopaedic surgeons who have a varied practice with regard to navigated TKA with some surgeons using navigation for all cases, some for what are deemed difficult cases and others using it rarely or not at all. One mechanical jig-based system and two different navigation systems are in routine use. The results from the two navigated (nav 1 and nav 2) and non-navigated (non-nav) systems were audited and compared with published studies to determine whether the reported results from randomised controlled trials were reproduced in our routine practice. The primary outcome measure was the mechanical femorotibial (MFT) angle as measured by Hip-Knee-Ankle (HKA) radiographs. This is a standard outcome measure that allowed ready comparison with other studies. Demographic data and post-operative MFT angles were collected retrospectively for each patient. The HKA digital radiographs (stored on a Picture Archive and Communication system) were taken six to twelve weeks post-operatively. The MFT angle was measured using a standardised protocol, which used the method of Mose to find the centre of the femoral head, the highest point in the femoral notch as the centre of the knee and the middle of the talus for the centre of the ankle. Repeated measurements were taken to identify intra- and inter-observer error. There were 86 patients in the nav 1 series, 95 in nav 2 and 95 in non-nav. Mean age was nav 1 = 70, nav 2 = 69 and non-nav = 71. Mean BMI was nav 1 = 34, nav 2 = 31.5 and non-nav = 30. Male to female ratio was nav 1 = 51:35, nav 2 = 44:51 and non-nav = 30:65. Intra- and inter- observer comparison showed a maximum difference of 1° for the measurement of MFT angle. For series nav 1 74% of TKAs had a MFT angle in the range ±3°, for series nav 2 this was 85% and for the non-nav series it was 68%. Much of the literature on
Aims. Rotator cuff tear (RCT) is the leading cause of shoulder pain, primarily associated with age-related tendon degeneration. This study aimed to elucidate the potential differential gene expressions in tendons across different age groups, and to investigate their roles in tendon degeneration. Methods. Linear regression and differential expression (DE) analyses were performed on two transcriptome profiling datasets of torn supraspinatus tendons to identify age-related genes. Subsequent functional analyses were conducted on these candidate genes to explore their potential roles in tendon ageing. Additionally, a secondary DE analysis was performed on candidate genes by comparing their expressions between lesioned and normal tendons to explore their correlations with
Aims. This systematic review places a recently completed multicentre randomized controlled trial (RCT), UK FROST, in the context of existing randomized evidence for the management of primary frozen shoulder. UK FROST compared the effectiveness of pre-specified physiotherapy techniques with a steroid injection (PTSI), manipulation under anaesthesia (MUA) with a steroid injection, and arthroscopic capsular release (ACR). This review updates a 2012 review focusing on the effectiveness of MUA, ACR, hydrodilatation, and PTSI. Methods. MEDLINE, Embase, PEDro, Science Citation Index, Clinicaltrials.gov, CENTRAL, and the World Health Organization (WHO) International Clinical Trials Registry were searched up to December 2018. Reference lists of included studies were screened. No language restrictions applied. Eligible studies were
Aims. There has been an increasing use of early operative fixation for scaphoid fractures, despite uncertain evidence. We conducted a meta-analysis to evaluate up-to-date evidence from randomized controlled trials (RCTs), comparing the effectiveness of the operative and nonoperative treatment of undisplaced and minimally displaced (≤ 2 mm displacement) scaphoid fractures. Methods. A systematic review of seven databases was performed from the dates of their inception until the end of March 2021 to identify eligible
Aims. Early large treatment effects can arise in small studies, which lessen as more data accumulate. This study aimed to retrospectively examine whether early treatment effects occurred for two multicentre orthopaedic randomized controlled trials (RCTs) and explore biases related to this. Methods. Included
The principal of “function priority, early rehabilitation, and return to sports” is now the goal for sports injury rehabilitation. Neuromuscular electrical stimulation for anterior cruciate ligament (ACL) reconstruction is a rising procedure for early rehabilitation. This paper systematically assessed the effects of neuromuscular electrical stimulation on postoperative ACL reconstruction to provide guidance for physiotherapist and patient when designing a suitable rehabilitation protocol. To evaluate the interventional outcomes of neuromuscular electrical stimulation following ACL reconstruction, we searched PubMed, EMbase, the Cochrane Library, Web of Science and CNKI to collect all randomized controlled trials (RCTs) comparing the effects with neuromuscular electrical stimulation and without intervention on rehabilitation after ACL reconstruction up to January 30, 2022. Two investigators independently performed literature screening, data extraction, bias assessment of risk, and used RevMan 5.3 software to conduct a meta-analysis. A total of six
There remains much debate regarding the optimal method for surgical management of patients with long head of biceps pathology. The aim of this study was to compare the outcomes of tenotomy versus tenodesis. This systematic review and meta-analysis was registered on PROSPERO (ref: CRD42020198658). Electronic databases searched included EMBASE, Medline, PsycINFO, and Cochrane Library. Randomized controlled trials (RCTs) comparing tenotomy versus tenodesis were included. Risk of bias within studies was assessed using the Cochrane risk of bias v2.0 tool and the Jadad score. The primary outcome included patient reported functional outcome measures pooled using standardized mean difference (SMD) and a random effects model. Secondary outcome measures included pain (visual analogue scale VAS), rate of Popeye deformity, and operative time. 860 patients from 11
Abstract. Objectives. There is debate regarding the optimal surgical technique for fixing femoral diaphyseal fractures in children aged 4 to 12 years.

Abstract. Introduction. This study aimed to assess the effect of PRP on knee articular cartilage content (thickness and/or volume) and establish if there is a correlation between changes in cartilage and clinical outcomes in patients with knee osteoarthritis. Methodology. A systematic review was performed following the Cochrane methodology. Studies were included if they reported on cartilage content with MRI or Ultrasound before and after the injection. A random-effects model meta-analysis was performed. Results. 11 studies (n=786) from 1,453 records met the inclusion criteria, with five (n=444) being
In recent literature, the fragility index (FI) has been used to evaluate the robustness of statistically significant findings of dichotomous outcomes. This metric is defined as the minimum number of outcome events to flip study conclusions from significant to nonsignificant. Orthopaedics literature is frequently found to be fragile with a median FI of 2 in 150
Aims. Intra-articular (IA) injection may be used when treating hip osteoarthritis (OA). Common injections include steroids, hyaluronic acid (HA), local anaesthetic, and platelet-rich plasma (PRP). Network meta-analysis allows for comparisons between two or more treatment groups and uses direct and indirect comparisons between interventions. This network meta-analysis aims to compare the efficacy of various IA injections used in the management of hip OA with a follow-up of up to six months. Methods. This systematic review and network meta-analysis used a Bayesian random-effects model to evaluate the direct and indirect comparisons among all treatment options. PubMed, Web of Science, Clinicaltrial.gov, EMBASE, MEDLINE, and the Cochrane Library were searched from inception to February 2023. Randomized controlled trials (RCTs) which evaluate the efficacy of HA, PRP, local anaesthetic, steroid, steroid+anaesthetic, HA+PRP, and physiological saline injection as a placebo, for patients with hip OA were included. Results. In this meta-analysis of 16
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
Considerable debate exists regarding which agent(s) should be preferred for venous thromboembolism (VTE) chemical prophylaxis following joint replacement. We assessed the practice of surgeons regarding VTE chemical prophylaxis for primary THR and TKR, pre and post issuing of updated NICE guidance in 2018. A survey, circulated through the British Hip Society and regional trainee networks/collaboratives, was completed by 306 UK surgeons at 187 units. VTE chemical prophylaxis prescribing patterns for surgeons carrying out primary THR (n=258) and TKR (n=253) in low-risk patients were assessed post publication of 2018 NICE recommendations. Prescribing patterns before and after the NICE publication were subsequently explored. Questions were also asked about surgeon equipoise for participation in future
