Abstract

A total of 55 consecutive cementless total hip arthroplasties were done for osteoarthritis by 1 surgeon, who was not a designer of the implant, using 1 surgical technique and Porous-Coated Anatomic (Howmedica, Rutherford, NJ) hip implants. Of hips, 53 were prospectively evaluated, and 39 were followed for an average of 12.3 years (range, 10-16 years). Eight patients (8 hips) died, and 6 of 53 hips (11.3%) required revision for aseptic loosening at an average of 6.5 years. Five of 53 (9.4%) acetabular components were revised at an average of 7.9 years. Four of 53 (7.6%) femoral components were revised at an average of 5.1 years. Survivorship of these total hip arthroplasties was 98 +/- 3.9 at 5 years, 88.9 +/- 9.2 at 10 years, and 86.7 +/- 9.9 at 13 years with revision as the endpoint.

摘要

一位并非植入物设计者的外科医生采用一种手术技术，使用多孔涂层解剖型（豪美迪克公司，新泽西州卢瑟福）髋关节植入物，为骨关节炎患者连续实施了55例非骨水泥型全髋关节置换术。其中53例髋关节接受了前瞻性评估，39例平均随访12.3年（范围为10至16年）。8例患者（8个髋关节）死亡，53个髋关节中有6个（11.3%）因无菌性松动平均在6.5年时需要翻修。53个髋臼组件中有5个（9.4%）平均在7.9年时进行了翻修。53个股骨组件中有4个（7.6%）平均在5.1年时进行了翻修。以翻修为终点，这些全髋关节置换术在5年时的生存率为98±3.9，10年时为88.9±9.2，13年时为86.7±9.9。
