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.
自21世纪初以来，氧化锆植入物因其耐磨性以及对金属过敏患者的适用性，已成为全髋关节和膝关节置换术中一种有价值的选择。这些部件的表面是通过锆合金的加热和氧化过程形成的，从而产生一层具有良好耐磨性能的薄层。然而，很少有报告指出，氧化锆部件通过各种机制意外磨损会导致严重的金属沉着病，包括聚乙烯衬垫分离和关节不稳定。我们报告了一例氧化锆全膝关节置换术出现严重失败的病例，需要进行分期翻修置换术。
