This study evaluated the 5- to 19-year clinical and radiographic results of cementless acetabular revision. Between 1986 and 1998, 130 hips (125 patients) underwent cementless acetabular revisions. Ten patients were lost to follow-up; 6 patients died. One hundred nine patients (114 hips) were reviewed at a mean follow-up of 8.8 years. The mean Harris hip score improved from 62.1 to 90.7 at final follow-up. Two hips underwent repeat revision. Twenty-two hips developed cavitary osteolysis. Kaplan-Meier survivorship at 121 months was 98.2% with repeat revision for any reason as the end point and 89.5% with repeat revision or radiographic loosening as the end point. Cementless acetabular revision provides favorable clinical and radiographic results, and the initial disease and age may adversely affect the outcomes.
本研究评估了非骨水泥型髋臼翻修术5至19年的临床和影像学结果。1986年至1998年间，130例髋关节（125例患者）接受了非骨水泥型髋臼翻修术。10例患者失访；6例患者死亡。对109例患者（114个髋关节）进行了评估，平均随访时间为8.8年。末次随访时，Harris髋关节评分平均从62.1提高到90.7。2个髋关节接受了再次翻修。22个髋关节出现了空洞性骨溶解。以因任何原因进行再次翻修为终点，121个月时的Kaplan-Meier生存率为98.2%；以再次翻修或影像学松动为终点，生存率为89.5%。非骨水泥型髋臼翻修术可提供良好的临床和影像学结果，初始疾病和年龄可能对结果产生不利影响。
