A survivorship analysis of 1,151 Charnley low-friction total hip arthroplasties performed as a primary procedure showed the following 15-year failure probabilities: hip revision 13%, cup revision 8%, femoral revision 12%, radiographic femoral loosening 13%, and radiographic cup loosening 49%. Pain scores diminished gradually with time so that at 15 years, the probability of a Charnley pain score less than 5 was 70%. The data suggest that the Charnley low-friction hip arthroplasty has a finite life span.
对1151例作为初次手术进行的Charnley低摩擦全髋关节置换术进行的生存分析显示了以下15年的失败概率：髋关节翻修13%，髋臼翻修8%，股骨翻修12%，影像学股骨松动13%，以及影像学髋臼松动49%。疼痛评分随时间逐渐降低，因此在15年时，Charnley疼痛评分低于5分的概率为70%。数据表明，Charnley低摩擦髋关节置换术具有有限的使用寿命。
