The purpose of this study was to report our clinical outcome of a large series of metal-on-metal hip resurfacing arthroplasty (HRA) using the hybrid Biomet ReCap-Magnum system. This is a single-designer surgeon series with an average of 5 ± 1 years. Seven hundred forty consecutive hybrid HRAs were performed in 653 patients. Kaplan-Meier survivorship with any revision as an end point was 96.4% at 7 years. Twenty-five (3.4%) cases were revised: 8 due to acetabular component loosening, 6 due to femoral neck facture, 4 due to failure of femoral component fixation, 2 due to deep infection, 2 due to adverse wear, 1 due to psoas tendonitis, 1 due to recurrent dislocation, and 1 due to unexplained pain. Biomet ReCap and Magnum HRA components with hybrid fixation methods showed excellent survivorship for a minimally selected young patient cohort at 7 years.
本研究旨在报告使用 Biomet ReCap-Magnum 混合系统进行的大量金属对金属髋关节表面置换术（HRA）的临床结果。这是一项单设计师外科医生系列研究，平均随访时间为 5 ± 1 年。在 653 名患者中，共进行了 740 例连续的混合 HRA。以任何翻修为终点的 Kaplan-Meier 生存率为 7 年时的 96.4%。25 例（3.4%）进行了翻修：8 例因髋臼组件松动，6 例因股骨颈骨折，4 例因股骨组件固定失败，2 例因深部感染，2 例因不良磨损，1 例因腰大肌腱炎，1 例因复发性脱位，1 例因不明原因疼痛。对于经过最小选择的年轻患者队列，使用混合固定方法的 Biomet ReCap 和 Magnum HRA 组件在 7 年内具有出色的生存率。
