The purpose of the present study was to evaluate the outcome of primary uncemented total hip arthroplasty in patients younger than 50 years using the Taperloc (Biomet, Warsaw, Ind) femoral component. We evaluated 94 hips in 79 patients at a mean follow-up of 16 years (range, 11-18.5 years). The average age of the patients at the time of surgery was 36 years (range, 20-49 years). Three femoral components had been revised, none for aseptic loosening. Complete clinical and radiographic follow-up was obtained on the 91 hips that had not undergone femoral component revision. The mean Harris hip score increased from 54 points (range, 20-72) before surgery to 93 points (range, 68-100) at the time of this review. Radiographically, 89 stems (98%) were determined to have fixation by bone ingrowth, 2 (2%) demonstrated stable fibrous ingrowth, and no femoral component was loose. Distal femoral osteolysis was identified in 1 hip (1%). These findings indicate that excellent clinical and radiographic results can be achieved in young patients with the Taperloc femoral component at a mean follow-up of 16 years.
本研究旨在评估使用 Taperloc（Biomet，印第安纳州华沙）股骨组件的初次非骨水泥全髋关节置换术在 50 岁以下患者中的治疗效果。我们对 79 例患者的 94 髋进行了评估，平均随访 16 年（范围 11-18.5 年）。患者的平均手术年龄为 36 岁（范围 20-49 岁）。有 3 个股骨组件进行了翻修，均非无菌性松动所致。未进行股骨组件翻修的 91 髋获得了完整的临床和影像学随访。Harris 髋关节评分由术前的 54 分（范围 20-72）增加至本次随访时的 93 分（范围 68-100）。影像学上，89 个柄（98%）被确定为骨长入固定，2 个（2%）显示稳定的纤维性长入，无股骨组件松动。1 髋（1%）发现股骨远端溶骨。这些发现表明，在平均随访 16 年的情况下，Taperloc 股骨组件可使年轻患者获得良好的临床和影像学结果。
