摘要

自 21 世纪初以来，氧化锆植入物因其耐磨性和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的重要选择。这些组件的表面是通过对锆合金进行加热和氧化处理而形成的，形成的薄层具有良好的耐磨性能。然而，关于氧化锆组件因意外磨损而导致严重金属中毒的报道并不多，其机制多种多样，包括聚乙烯衬垫解离和关节不稳定。我们介绍了一例氧化锆全膝关节置换术的严重失败病例，患者不得不进行分期翻修关节置换术。

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

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.

期刊介绍： Arthroplasty Today is a companion journal to the Journal of Arthroplasty. The journal Arthroplasty Today brings together the clinical and scientific foundations for joint replacement of the hip and knee in an open-access, online format. Arthroplasty Today solicits manuscripts of the highest quality from all areas of scientific endeavor that relate to joint replacement or the treatment of its complications, including those dealing with patient outcomes, economic and policy issues, prosthetic design, biomechanics, biomaterials, and biologic response to arthroplasty. The journal focuses on case reports. It is the purpose of Arthroplasty Today to present material to practicing orthopaedic surgeons that will keep them abreast of developments in the field, prove useful in the care of patients, and aid in understanding the scientific foundation of this subspecialty area of joint replacement. The international members of the Editorial Board provide a worldwide perspective for the journal''s area of interest. Their participation ensures that each issue of Arthroplasty Today provides the reader with timely, peer-reviewed articles of the highest quality.
