title: Clinical studies of second revision in total hip replacement.
abstract: Eleven patients (12 hips) underwent the second revision of total hip replacement. The mean age at the second revision was 61 years (range: 31 to 79); 2 patients were men and 9 women. Loosening of components was the most common reason for the revision surgery. Supplemental ring or wire-mesh reinforcement was used for the revision of the acetabular that had poor bone stock. On the acetabular side, an allograft was used in 4 hips; on the femoral side, a long stem was used in 11 hips. The mean operative time was 298 minutes (range: 195 to 525), and the mean bleeding volume was 2278 ml (range: 810 to 4800) which was about twofold more than that of the primary operation. The mean length of follow up after the second revision was approximately 5 years. In the clinical results, the mean total Japan Orthopaedic Association score was 56 points before the second revision and it was 70 points during the follow-up period. Pain score was especially improved after the second revision. On final roentgenographic examination there was noted a clear zone in three acetabular components and five femoral components. As yet, we have not experienced any case requiring a third revision.
