Eleven cases (12 hips) underwent second revision of a 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 a component was the most common reason for the revision. Supplemental rings or wire-mesh reinforcements were used for 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) . The mean length of follow up after the second revision was approximately 5 years.
The clinical results were a mean total JOA score of approximately 70 in the maximum period of follow up. In the final roentgenographic examinations there was a clear zone with 3 acetabular components and 5 femoral components, and loosening of 1 acetabular component and 2 femoral components. We have yet to experience a third revision.
