Unicompartimental knee arthroplasty is a successful procedure for the treatment of localized osteoarthritis to one compartment of the knee with good long-term results. However, several modes of failure of unicompartimental knee arthroplasty have been described, namely aseptic or septic loosening, progression of disease, wear, and instability. Metallosis after unicompartimental knee arthroplasty is rarely reported and is most often related with polyethylene wear or break. We report on a case of rapid failure of unicompartimental knee arthroplasty in oxidized zirconium associated with metallosis secondary to the dislocation of the polyethylene.
单髁膝关节置换术是治疗膝关节单髁局限性骨关节炎的一种成功手术方法，长期效果良好。然而，已有多种单髁膝关节置换术失败的模式被描述，即无菌性或感染性松动、疾病进展、磨损和不稳定。单髁膝关节置换术后金属沉着症鲜有报道，且大多与聚乙烯磨损或破裂有关。我们报告一例氧化锆单髁膝关节置换术快速失败的病例，该病例与聚乙烯脱位继发的金属沉着症有关。
