Factors influencing UK arthroplasty surgeons' decision-making between total and medial unicompartmental knee surgery: A vignette-based behavioural experiment.

Purpose: Surgical options for end-stage knee osteoarthritis (OA) include total and medial unicompartmental knee replacement (TKR and UKR). Deciding which surgery to perform is complex and ill-defined, yet it has important implications for patients and the health service. The study aimed to identify clinical and surgeon factors predicting surgeons' preferences.

The prevalence of, and risk factors for distal femoral cortical irregularity in the adolescent population.

Introduction: There is uncertainty around the pathogenesis and prevalence of distal femoral cortical irregularities (DFCI). We aimed to assess the prevalence of DFCI in a cohort of adolescents that underwent MRI and identify and assess associated risk factors.

Methods: A historical cohort study of adolescents (age 10 - <20 years) undergoing MRI scans was conducted.

Femoral tunnel enlargement after medial patellofemoral ligament reconstruction is common and can be monitored using plain radiographs.

Introduction: medial patellofemoral ligament reconstruction (MPFLr) is a common surgical procedure for treating patellar instability. Grafts can be fixed to the femur using a bone-tunnel technique with an interference screw. However, this may lead to femoral tunnel enlargement (FTE) post-operatively.
