Dramatic Failure of an OXINIUM Total Knee Arthroplasty With a Massive Pseudotumor Formation

Year: 2024

Type: article

Abstract: Since the early 2000s, oxidized zirconium implants have emerged as a valuable option in total hip and knee arthroplasty due to their wear resistance and suitability for patients with metal hypersensitivity. The surface of these components is created through a heating and oxidation process of a zirconium alloy, resulting in a thin layer with favorable wear properties. However, there have been few reports of severe metallosis resulting from inadvertent wear of oxidized zirconium components through various mechanisms, including dissociation of the polyethylene liner and joint instability. We present a case involving a dramatic failure of an oxidized zirconium total knee arthroplasty, necessitating a staged revision arthroplasty.
