Adverse reactions to metal debris in relation to metal-on-metal hip arthroplasty has been heavily discussed in the literature. In contrast, few cases have been reported in the context of total knee arthroplasty. A 77-year-old woman presented with a painful total knee arthroplasty. At the time of revision surgery, intra-articular cream-coloured fluid and material was found in association with a well-fixed prosthesis. Synovial and capsular samples were obtained for histological assessment and a diagnosis of aseptic lymphocytic vasculitis associated lesion was confirmed. The patient went on to have an uncomplicated recovery following a two-stage revision to a constrained knee prosthesis.

Farmers may be at a higher risk of developing hip osteoarthritis (OA) due to the high demands of their occupation. To the authors' knowledge, the gait patterns of farmers that may be associated with hip joint degeneration have yet to be analyzed. Therefore, this study compares gait mechanics between farmers and non-farmers (controls).

Purpose: Studies evaluating the long-term survival rate, patient satisfaction, and conversion to total hip arthroplasty (THA) are limited. The aim of this study was to evaluate satisfaction and hip survival at a minimum 10-year follow-up in patients following hip arthroscopy for femoroacetabular impingement syndrome (FAIS).

Methods: A total of 164 patients underwent hip arthroscopy for FAIS between 2007 and 2012; of these, 76 (49 men and 27 women; mean age, 40.

Background This is a retrospective service evaluation of outcomes of polytrauma patients sustaining knee dislocations and subluxations within a major trauma center (MTC). Polytrauma patients with knee dislocations are complex to manage and often sustain multiple life-threatening injuries. Although treatments have progressed, no consensus remains on management timing and strategy.
