We evaluated the performance of a contemporary cementless acetabular component at a minimum of 5 years postoperatively. One hundred eighty-seven consecutive acetabular component revisions were performed using a hemispherical porous-coated component. Patients were followed prospectively with radiographs and Harris hip scores. Twenty patients died, leaving 158 patients (166 hips) available for follow-up at a mean of 91 months. No patients were lost. Eleven acetabular components (7%) required repeated revision, including 4 (2%) for aseptic loosening. Seven of the 145 unrevised acetabular components with radiographic follow-up (5%) were loose. The results of acetabular revision with this contemporary acetabular component were good but inferior to those of earlier-generation implants. This difference is likely multifactorial.
我们评估了一种新型非骨水泥髋臼假体在术后至少 5 年的性能。187 例连续髋臼假体翻修采用半球形多孔涂层假体。前瞻性随访患者的 X 线片和 Harris 髋关节评分。20 例患者死亡，158 例（166 髋）患者平均随访 91 个月，无失访。11 例髋臼假体（7%）需要再次翻修，包括 4 例（2%）因无菌性松动。145 例髋臼假体中有 7 例（5%）在 X 线随访中松动。该新型髋臼假体的髋臼翻修效果良好，但劣于早期植入物。这种差异可能是多因素的。
