Introduction. Osteochondral defects (OCDs) of the talus were identified as a “TOP 10” research priority in foot and ankle surgery by the James Lund Alliance in partnership with BOFAS, BOA and NIHR. To develop a research strategy, the views of BOFAS members regarding OCDs of the talus were surveyed. The results are reported here. Methods. A questionnaire concerning the presentation, investigation and management of OCDs was formulated with input from the BOFAS National Clinical Study Group and ratified by the Scientific Committee. It concerned primary OCDs of the talus that had failed non-surgical management. It was distributed to BOFAS members via email using _Microsoft Forms_. Results. There were 90 responses. Data on presenting symptoms, investigations, initial management and decision making was collected. Surgical treatment was grouped according to defect size: small or large and shallow or deep. This gave 4 categories. For the purposes of the study a large defect had a width >15mm and a deep defect had a depth >5mm. For small, shallow lesions 85 respondents chose microfracture as the first line surgical treatment. For large shallow lesions 59 respondents chose microfracture, 18 chose bone marrow stimulation plus scaffold e.g. AMIC or ACIC and 6 chose bone marrow stimulation plus a biological agent e.g. cBMA or PRP. For small deep lesions microfracture was again most popular (69 respondents). For large deep lesions microfracture was chosen by 43 respondents, AMIC/ACIC by 23 and OATs by 7. Further data was collected on post op rehabilitation. Discussion. The study demonstrates that microfracture is the most popular first line treatment for primary OCDs of the talus of any size. That said, a wide range of treatments are in practice. This information will facilitate the development of high-quality studies to identify the most appropriate evidence-based treatment for OCDs of the talus

Aims. First metatarsal Pronation is increasingly recognised as an important component of Hallux valgus (HV) and can contribute towards intraoperative malreduction, postoperative recurrence and patient reported outcome measures (1,2,3). There are numerous radiological ways to measure metatarsal rotation on plain radiographs and weight bearing CT (WBCT), however there are no clinical tests to evaluate metatarsal pronation pre- or intra-operatively. This study therefore aimed to examine the relationship between clinical pronation of the toe and metatarsal pronation. Methods. Single-centre, retrospective analysis over 5 years. Measurements were performed on WBCT images with digital reconstructions to add soft tissues. First metatarsal rotation was measured using the Metatarsal Pronation Angle as previously described (4). Toe rotation was measured by the Phalangeal Condylar Angle (PCA), the angle between the condyles of the proximal phalanx and the floor, and the Nail Plate Angle (NPA), the angle of the base of the nail plate to the floor in the coronal Plane. These were obtained from 50 feet in Hallux valgus patients, and 50 control patients with CTs done for osteochondral lesions without hallux valgus or hindfoot malalignment. Results. The HV group comprised 41 women and 9 men, mean age 52.4. Control group, 23 women and 23 male, mean age 40.25. Inter and Intra Observer reliability both excellent (ICC >0.95) for all measurements. When comparing HV vs control, MPA was 11.7 vs 6.0 (p<0.001), PCA 31.8 vs 4.7 (p<0.001), NPA 18.3 vs 6.0 (p<0.0001). NPA correlated with PCA. NPA and PCA correlate with Hallux valgus Angle (p<0.001), but not with MPA (p 0.567). Conclusion. These results suggest that clinical toe pronation increases as HV angle increases but not with metatarsal pronation, which therefore cannot be used as a clinical marker. Toe pronation is similar at the base and at the nail, suggesting rotation happens at the MTPJ

Aims

Unicompartmental knee arthroplasty (UKA) is associated with an accelerated recovery, improved functional outcomes, and retention of anatomical knee kinematics when compared to manual total knee arthroplasty (mTKA). UKA is not universally employed by all surgeons as there is a higher revision risk when compared to mTKA. Robotic arm-assisted (ra) UKA enables the surgeon to position the prosthesis more accurately when compared to manual UKA, and is associated with improved functional outcomes and a lower early revision risk. Non-randomized data suggests that, when compared to mTKA, raUKA has a clinically meaningful greater functional benefit. This protocol describes a randomized controlled trial that aims to evaluate the clinical and cost-effectiveness of raUKA compared to mTKA for individuals with isolated medial compartment osteoarthritis (OA).

Aims

The Bracing Adolescent Idiopathic Scoliosis (BASIS) study is a randomized controlled non-inferiority pragmatic trial of ‘full-time bracing’ (FTB) compared to ‘night-time bracing’ (NTB) for the treatment of adolescent idiopathic scoliosis (AIS). We anticipated that recruiting patients to BASIS would be challenging, as it is a paediatric trial comparing two markedly different bracing pathways. No previous studies have compared the experiences of AIS patients treated with FTB to those treated with NTB. This qualitative study was embedded in BASIS to explore families’ perspectives of BASIS, to inform trial communication, and to identify strategies to support patients treated in a brace.

Aims

Autologous bone graft (ABG) is considered the ‘gold standard’ among graft materials for bone regeneration. However, complications including limited availability, donor site morbidity, and deterioration of regenerative capacity over time have been reported. P-15 is a synthetic peptide that mimics the cell binding domain of Type-I collagen. This peptide stimulates new bone formation by enhancing osteogenic cell attachment, proliferation, and differentiation. The objective of this study was to conduct a systematic literature review to determine the clinical efficacy and safety of P-15 peptide in bone regeneration throughout the skeletal system.

Aims. Older adults with hip fractures are at high risk of experiencing complications after surgery, but estimates of the rate of specific complications vary by study design and follow-up period. The aim of this systematic review was to determine the prevalence of complications in older adults after hip fracture surgery. Methods. MEDLINE, Embase, CINAHL, and CENTRAL databases were searched from inception until 30 June 2023. Studies were included if they reported prevalence data of complications in an unselected, consecutive population of older adults (aged ≥ 60 years) undergoing hip fracture surgery. Results. A total of 95 studies representing 2,521,300 patients were included. For surgery-specific complications, the 30-day prevalence of reoperation was 2.31%, surgical site infection 1.69%, and deep surgical site infection 0.98%; the 365-day prevalence of prosthesis dislocation was 1.11%, fixation failure 1.77%, and periprosthetic or peri-implant fracture 2.23%. For general complications, the 30-day prevalence of acute kidney injury was 1.21%, blood transfusion 25.55%, cerebrovascular accident 0.79%, lower respiratory tract infection 4.08%, myocardial infarction 1.98%, urinary tract infection 7.01%, and venous thromboembolism 2.15%. Conclusion. Complications are prevalent in older adults who have had surgery for a hip fracture. Studies reporting complications after hip fracture surgery varied widely in terms of quality, and we advocate for the routine monitoring of complications in registries and clinical trials to improve the quality of evidence.

Aims

The aim of this study was to evaluate the suitability, against an accepted international standard, of a linked hip fracture registry and routinely collected administrative dataset in England to embed and deliver randomized controlled trials (RCTs).

Aims

While cementless fixation offers potential advantages over cemented fixation, such as a shorter operating time, concerns linger over its higher cost and increased risk of periprosthetic fractures. If the risk of fracture can be forecasted, it would aid the shared decision-making process related to cementless stems. Our study aimed to develop and validate predictive models of periprosthetic femoral fracture (PPFF) necessitating revision and reoperation after elective total hip arthroplasty (THA).

Aims

Ultrasound-guided injection techniques are expected to enhance therapeutic efficacy for skeletal muscle injuries and disorders, but basic knowledge is lacking. The purpose of this study was to examine the diagnostic accuracy of ultrasound for abnormal skeletal muscle lesions, and to examine the distribution patterns of solution and cells injected into abnormal muscle lesions under ultrasound guidance.

Aims

The primary aim of this study is to compare mobility status of patients receiving oral oxycodone with those receiving subcutaneous alfentanil as analgesic methods prior to mobilization to help physiotherapy compliance after hip fracture surgery. The secondary aims are to assess postoperative pain, health-related quality of life, in-hospital length of stay, total use of analgesia over postoperative days 1 and 2 (POD 1 and POD 2), complication rates within 30 days, and 30-day mortality rates.

Aims

This study aims to define a set of family-centred core outcomes for infants undergoing brace treatment to facilitate consistent reporting for future high-quality research.
