Bone defect is a serious problem in revision arthroplasty. Allograft serves as a solution for restoring bone defects. This paper describes the incidence of allograft for acetabular revisions in our department and examines the clinical outcomes. Between 1992 and 1999, 72 acetabular revisions were performed. Forty-eight (67%) revisions were with bone grafts, and, in 36 grafts, allogenic bones were used. In cases with allografts that had at least one-year follow-up after operation (mean follow-up period: 3.8 years), there were no re-revisions or cases in which radiographical loosening was observed.
