Despite overall good survivorship and clinical outcomes in the short term after total hip arthroplasty (THA) with use of alumina ceramic-on-highly cross-linked polyethylene (HXLPE) in patients younger than 30 years of age, there is a paucity of long-term data to evaluate the fixation of the components and the prevalence of osteolysis. We reviewed the records of 45 patients (54 hips) who had been included in a previous report to evaluate the long-term functional outcomes as well as radiographic and computed tomographic scan findings (particularly with regard to component fixation and osteolysis) after a mean duration of follow-up of 17.8 years. One femoral stem was revised because of aseptic loosening, and 2 acetabular components were revised because of recurrent dislocation. The survival rate at 17.8 years was 98% for the femoral component and 96% for the acetabular component. LEVEL OF EVIDENCE:: Therapeutic Level IV. See Instructions for Authors for a complete description of level of evidence.
尽管在 30 岁以下的患者中使用氧化铝陶瓷-高交联聚乙烯（HXLPE）进行全髋关节置换术（THA）后，总体上有良好的存活率和短期临床结果，但缺乏长期数据来评估组件的固定和溶骨的发生率。我们回顾了之前报告中纳入的 45 名患者（54 髋）的记录，以评估平均随访 17.8 年后的长期功能结果以及影像学和计算机断层扫描结果（特别是关于组件固定和溶骨）。由于无菌性松动，1 个股骨柄进行了翻修，由于反复脱位，2 个髋臼组件进行了翻修。17.8 年后，股骨部件的存活率为 98%，髋臼部件的存活率为 96%。证据水平：治疗水平 IV。有关证据水平的完整描述，请参阅作者说明。
