Severe metallosis after unicompartmental knee arthroplasty

Vicente Sanchis-Alfonso. Knee Surg Sports Traumatol Arthrosc. 2007 Apr.

Abstract

We report on a case of a patient who had femoral osteolysis and severe metallosis of the knee joint resulting from the secondary abrasive wear of the metal-backed tibial component of a unicompartmental knee arthroplasty due to massive wear of tibial polyethylene. The failure was diagnosed 11 years after implantation. This metallosis affected the intra-articular tissues and the subchondral bone.
