Structural bone grafts in acetabular reconstruction of total hip arthroplasty have come into more common usage with the increasing number of revision arthroplasties. The authors present the outcome of 40 bone grafts with follow-up periods of 2–8 years. Primary and revision arthroplasties with both cemented and noncemented fixation are included. Factors that had a statistically significant relationship to failure of the bone graft included fit and fixation of bone graft to host, fit and fixation of prosthesis to host, union of bone graft to host, and the presence or absence of the confluence of the anterior and posterior columns of the acetabulum. Other findings of interest were a higher failure rate of multiple grafts as compared to a single graft and freeze-dried femoral heads. Migration of the socket of more than 3 mm is statistically related to failure of the socket
