ABSTRACT
Metallosis is a known yet rare late complication of unicompartmental and total knee arthroplasty (TKA), usually secondary to either metal-backed patellar component failure, mobile-bearing polyethylene dislocation, or catastrophic polyethylene failure and wear through. The majority of literature surrounding metallosis has been published in relation to total hip arthroplasty (THA) metal on metal bearing wear or mechanically assisted crevice corrosion.This case report describes the development of metallosis in a 77-year-old male patient with advanced (Kellgren-Lawrence Grade 4) osteoarthritis with associated valgus deformity, who underwent index TKA with a semiconstrained revision knee system due to intraoperative medial collateral ligament laxity. The taper junction between the titanium alloy stem and cobalt chromium femoral component was the source of diffuse intra-articular metallosis.
