Abstract
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.
