This study examined long-term survivorship of primary total hip arthroplasty (THA) using cementless Harris-Galante porous femoral and Harris-Galante porous I or II acetabular components. Of 113 hips (101 patients) studied, 60 hips (53 patients) were available for follow-up at a mean of 17.2 years after surgery. A total of 10 hips had documented revision, and 2 hips had failed radiographically. The average Harris hip score was 82. Radiographically, 12 hips demonstrated eccentric wear, 8 had osteolysis, and 1 had a broken tine. The overall survival rate was 87.7%; the mean volumetric wear rate was 74.96 mm(3); and the mean polyethylene linear penetration rate was 0.153 mm/y, similar to that of well-cemented THA in other series. This long-term outcome for an early-generation cementless THA is promising and provides a standard by which to judge the newer generation of cementless implants.
本研究采用非骨水泥 Harris-Galante 多孔股骨和 Harris-Galante 多孔 I 或 II 髋臼组件,评估初次全髋关节置换术(THA)的长期生存率。在研究的 113 髋(101 例患者)中,60 髋(53 例患者)在手术后平均 17.2 年时可进行随访。共有 10 髋有记录的翻修,2 髋影像学失败。平均 Harris 髋关节评分 82 分。影像学上,12 髋显示偏心磨损,8 髋有骨溶解,1 髋有叉骨断裂。总体生存率为 87.7%;平均容积磨损率为 74.96mm³;平均聚乙烯线性穿透率为 0.153mm/y,与其他系列中骨水泥固定 THA 的相似。这种早期非骨水泥 THA 的长期结果很有前景,为判断新一代非骨水泥植入物提供了标准。
