Abstract
From 1976 to 1981, 43 total hip replacements had been perfomed in 35 patients in our clinic. Of these, we were able to follow 17 joints in 13 patients for more than 10 years. Clinical assessment using the JOA hip score and radiological assessment using Nagaya's method were carried out pre and post-operatively. The incidence of a clear zone was 80% on the acetabular side and 82% on the femoral side. The rate of loosening of stage III and IV was 42% on the acetabular side and 53% on the femoral side. The revision rate was 29%. The average JOA hip score at 5 years was 84 points, decreasing to 75 points at 10 years. JOA hip score results were comparatively better than that of X-ray findings.
