Abstract
We reviewed 9 patients (10 hips) who had undergone a revision total hip replacement (revision THR) during the period from 1988 to 1992. Age at revision THR ranged from 64 to 75 years (average, 70 years).
In this follow-up study, the average pre-revisional and post-revisional JOA scores were 38 and 63 points respectively.
We evaluated the acetabular defects according to Hedley. We had 3 hips to be contained defect, and 5 hips to be noncontained defect. Of them all, 8 hips required additional acetabuloplasty with bone graft to provide bone stock. In 4 hips, revision surgery was performed by cemented acetabular cup.
