Early success has been reported using a long-stem cemented femoral component in total hip arthroplasty (THA). The same patient group reported by the authors' institution at five years were reviewed again at ten years postarthroplasty. Certain trends can now be defined, including gradual deterioration in the Harris hip score, tendency toward failure of acetabular fixation (8.4% loosening rate requiring revision), and increased calcar resorption. Overall, the cemented femoral component has performed admirably, with a 97% success rate at ten-years' post-THA (3.1% revision rate). In this study, success was defined as arthroplasties that did not require revision. Ninety percent of observed patients were rated as good or excellent using the Harris hip score. The Clayton femoral component provides excellent durability by virtue of design.
据报道，在全髋关节置换术（THA）中使用长柄骨水泥型股骨组件取得了早期成功。作者所在机构报告的同一组患者在置换术后五年时进行了研究，此次在置换术后十年时再次进行了回顾。现在可以确定某些趋势，包括Harris髋关节评分逐渐恶化、髋臼固定失败的倾向（8.4%的松动率需要翻修）以及股骨距吸收增加。总体而言，骨水泥型股骨组件表现出色，在THA术后十年的成功率为97%（翻修率为3.1%）。在本研究中，成功定义为不需要翻修的关节置换术。使用Harris髋关节评分，90%的观察患者被评为良好或优秀。Clayton股骨组件凭借其设计提供了出色的耐用性。
