A single surgeon performed 2,559 metal-on-metal hip resurfacing arthroplasties in 2,109 patients. The Corin Cormet 2000 (393 cases) and Biomet Recap implants (2,166 cases) were used in our series. In this study, the adverse wear failure (AWF) rate was 0.27%. At 10 years postoperatively, our Kaplan-Meier cumulative revision rate for AWF was 1% for all patients, 0.2% for men, 2.6% for women, and 9% for patients with a diagnosis of dysplasia. All AWF failures had component sizes ≤48 mm. All had metal ion levels above 15 ug/ml. All had acetabular inclination angles (AIA) ≥50° on standing pelvis radiographs. All had severe metallosis found at the time of revision. Six of the seven AWF cases were in women. There were no failures from pseudotumours without AWF (metallosis) in this series.
一位外科医生为2109例患者实施了2559例金属对金属髋关节表面置换术。本系列研究中使用了Corin Cormet 2000（393例）和Biomet Recap假体（2166例）。在本研究中，不良磨损失败（AWF）率为0.27%。术后10年，所有患者AWF的Kaplan-Meier累积翻修率为1%，男性为0.2%，女性为2.6%，发育异常诊断患者为9%。所有AWF失败病例的假体尺寸均≤48mm。所有患者的金属离子水平均高于15μg/ml。所有患者站立位骨盆X线片上的髋臼倾斜角（AIA）≥50°。所有患者翻修时均发现严重金属沉着病。7例AWF病例中有6例为女性。本系列中无无AWF（金属沉着病）的假瘤导致的失败病例。
