Knee osteochondral allograft transplantation (OCAT) has been associated with good short- to mid-term outcomes, however, treatment failures occur more frequently than desired. This study used data from a lifelong outcomes registry to analyze knee OCAT treatment failure rates, variables associated with knee OCAT treatment failures, and outcomes after revision or arthroplasty surgery for knee OCAT treatment failures ..read more

This study aimed to compare the regeneration status of articular cartilage, clinical, and radiologic outcomes between varus knee patients with and without preoperative tibial varus deformity (PTVD) after medial opening-wedge high tibial osteotomy (OWHTO ..read more

One of the remaining issues in total knee arthroplasty (TKA) is achieving sufficient rotational arc during deep flexion range of the knee for specific postures such as the ‘seiza’ or cross-legged sitting. This study aimed to evaluate whether there was a change in the actual in vivo rotational arc during deep flexion range before and after a design change of polyethylene (PE) inserts ..read more

Uncemented trabecular metal (TM) monoblock tibial components in total knee arthroplasty (TKA) have shown excellent clinical results for up to 10 years. However, these studies were performed in highly specialized units, with few surgeons and often excluding knees with secondary osteoarthritis (OA), severe malalignments and previous surgery. The purpose of this study was to investigate implant survivorship and clinical and radiological outcome of the uncemented TM high-flex posterior stabilized (PS) monoblock tibial component in routine clinical practice ..read more

Chronic pain is a major challenge for some people after total knee replacement (TKR). The changing impact of this complication during the first post-operative year remains unclear. This analysis aimed to examine how physical activity and health-related quality of life (HRQoL) evolved over the first year after TKR for patients with and without post-operative chronic knee pain ..read more

A multi-ligament knee injury (MLKI) is defined by the complete disruption of at least two stabilizing ligaments of the knee, and can occur with or without true knee dislocation, defined as the complete loss of tibiofemoral articulation [34,39]. Acute knee dislocation is a rare injury, accounting for 0.2% of orthopedic injuries annually [8,16,20,37]. MLKI are classically characterized using the Schenck anatomic classification system, based on the number of disrupted ligaments [13]. The Schenck classification has been previously utilized to identify associations of MLKI subtypes with rates of ne ..read more

At present, extended reality technologies such as virtual reality (VR) have gained popularity in orthopedic surgery. The first aim of this study was to assess the precision of VR and other imaging modalities – computed tomography (CT), magnetic resonance imaging (MRI) – to localize bony landmarks near the knee joint. Secondly, the impact of the educational level of the assessor – medical master students, orthopedic residents, and orthopedic surgeons – on the precision with which landmarks near the knee joint could be localized was analyzed ..read more

Augmented feedback strategies have been demonstrated to enhance jump-related biomechanics. Nevertheless, its effect on classical ballet is still unknown. The purpose of this study was to investigate whether a multimodal augmented feedback session is effective for improving lower limb and trunk kinematics during a classical ballet single-leg jump ..read more

Knee dislocations (KDs) are rare in orthopaedic trauma but can have devastating effects. Failing to diagnose a concomitant vascular injury can lead to amputation. Different methods are used for the diagnosis of a vascular injury and the best approach is under debate.This study aims to examine the risk factor(s) of vascular injury in patients with KDs, examine variables that differ between obese patients and non-obese patients with KDs, and analyse the modalities used to identify vascular injuries in the KD population ..read more
