本研究的目的是回顾性调查 109 名患者使用高度交联聚乙烯 (HXLPE) 进行的 113 例全髋关节置换术在中期（至少 7 年）随访后的结果。手术时的平均年龄为 57 岁。术前诊断为股骨头坏死81髋，其他诊断32髋。没有出现部件松动的情况。 12 髋（10.6/0）发现髋臼骨溶解。 HXLPE 平均线性磨损率为 0.031 +/- 0.012 毫米/年。我们分析了 HXLPE 磨损率与影响 HXLPE 磨损的几个变量之间的关系。只有杯位置与 HXLPE 的磨损率显着相关 (P < .05)。使用HXLPE进行全髋关节置换术的结果显示，中期随访后磨损率降低，骨质溶解发生率低，效果良好。
The purpose of this study was to investigate the results of 113 total hip arthroplasties in 109 patients using highly cross-linked polyethylene (HXLPE) after midterm (minimum 7 years) follow-up retrospectively. The mean age at the time of operation was 57 years. Preoperative diagnosis was osteonecrosis in 81 hips and other diagnosis in 32 hips. There was no component loosening. Acetabular osteolysis was found in 12 hips (10.6 /0). Mean linear HXLPE wear rate was 0.031 +/- 0.012 mm/y. We analyzed the relationship between HXLPE wear rate and several variables influencing HXLPE wear. Only the cup position was related with wear rate of HXLPE significantly (P < .05). The results of total hip arthroplasties using HXLPE showed excellent results with decreased wear rate and low incidence of osteolysis after midterm follow-up.
