After exclusion of 15 infected cases, 165 consecutive primary Charnley hip replacements for arthrosis were examined 5 and 10-13 years postoperatively. The failure rates during the first 5 years and between the 5- and 10-year follow-ups were 6 and 5 percent, respectively. Failures were more common in men. Among the hips followed for at least 10 years, 43 and 50 percent of the stems were radiographically loose at the 5- and 10-year follow-ups, respectively; the corresponding figures for the socket were 8 and 12 percent. No hips with radiographically intact components at 5 years were clinical failures at the 10-year follow-up.
排除15例感染病例后，对165例连续进行的因骨关节炎行Charnley髋关节初次置换术的患者在术后5年以及10至13年进行了检查。前5年和5至10年随访期间的失败率分别为6%和5%。失败在男性中更为常见。在至少随访10年的髋关节中，在5年和10年随访时，分别有43%和50%的股骨柄在X线片上显示松动；髋臼的相应数字为8%和12%。在5年时X线片显示假体组件完整的髋关节在10年随访时无临床失败病例。
