ABSTRACT

Polyethylene wear is a key contributor to long-term failure in total knee arthroplasty. Oxidized zirconium alloy was created as a bearing surface for total joint arthroplasty in an attempt to address this concern. Oxidized zirconium has shown considerable improvements over existing materials in several key areas related to component longevity, including resistance to roughening, wear reduction, frictional behavior and biocompatibility. This review aims to summarize the current use of oxidized zirconium alloy in knee arthroplasty, as well as the possible advantages and downsides of this material.
