Ten-year results of the Charnley hip in arthrosis

Abstract

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.
