Aseptic lymphocytic vasculitis-associated lesion in a well-fixed total knee arthroplasty: a case report.

ABSTRACT

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.
