Purpose: To compare the implant position and patient-reported outcomes (PROs) regarding joint awareness using the Forgotten Joint Score (FJS) following between fixed-bearing (FB) and mobile-bearing (MB) unicompartmental knee arthroplasty (UKA) with a minimum of five years' follow-up.
Methods: One hundred fifteen consecutive UKAs (58 FB UKAs and 57 MB UKAs) performed were retrospectively evaluated. We compared the radiographic parameters including component positions and relationships as well as lower extremity alignment. Post-operative clinical outcomes were assessed using Knee Society Score (KSS), the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) score, Tegner activity score, and FJS.
Results: The MB UKA group showed more convergent componentry relationship between femoral and tibial components (p < 0.001). The joint line of the MB UKA group was restored significantly better (p < 0.05). In addition, the positioning of femoral and tibial components of the MB UKA group showed less deviation from the weight-bearing line (WBL) (p < 0.05). Although there were no differences in KSS, WOMAC, and Tegner activity scores between the groups, the MB UKA group showed significantly better FJS than did the FB UKA group at five years post-operatively (p < 0.05).
Conclusion: The MB UKA group had a more convergent componentry relationship, less deviation from WBL, better joint-line restoration, and reduced joint awareness than did the FB UKA group at five years follow-up.

Background: Tibial bone fractures in the malleolar regions are a major concern during the early postoperative period of total ankle replacement (TAR), affecting patient outcomes such as stability and recovery. Design, placement, and anatomic misalignment of implant components can contribute to malleolar fractures. The aim of this study is to understand the influence of implant design features, including keel, peg, stem, and bar type design, and bone-implant interfacial conditions on malleolar fracture following TAR.

Introduction: Intertrochanteric fractures are common in older adults and pose significant challenges in terms of morbidity and mortality. Accurate reduction and optimal implant positioning during operative stabilisation of these fractures reduce the rates of complications and reoperations while improving functional outcomes in this population. This study aimed to assess the effects of a structured educational intervention on the radiographic outcomes, reduction quality, and revision rates of intertrochanteric fractures.

Removal of spontaneously fractured leads with their proximal ends migrated into the vascular space has not been analysed in detail thus far. The study aimed to compare the effectiveness of different approaches and auxiliary tools for removing fractured leads with migrated proximal ends. Retrospective analysis of 72 cases from a database containing 3847 TLEs (transvenous lead extraction).

: Hip fractures are prevalent among the elderly and impose a significant burden on healthcare systems due to the associated high morbidity and costs. The increasing use of intramedullary nails for hip fracture fixation has inadvertently introduced risks; these implants can alter bone elasticity and create stress concentrations, leading to peri-implant fractures. The aim of this study is to investigate the outcomes of peri-implant hip fractures, evaluate the potential causes of such fractures, determine the type of treatment provided, assess the outcomes of said treatments, and establish possible improvement strategies.

: A common problem in pediatric orthopedics is leg length discrepancy (LLD). In adulthood, this may result in overload and degenerative changes in the lumbar spine, hip, and knee joints of the longer limb, and the fixed equinus position of the foot of the shorter limb. Surgical treatment using temporary epiphysiodesis with eight-plate implants is a minimally invasive, safe, and patient-tolerated procedure in LLD.
