We have examined the results of 16 allografts (3 man and 13 woman) used in the revision of total hip arthroplasty (8 osteoarthritis and 8 non-osteoarthritis cases) between March 2003 and September 2004. The mean age at the time of surgery was 68 years (range: 49 to 80 years). The mean duration of follow-up was 19 months (range: 2 to 40 months). There were no differences in JOA scores before or after surgery between the OA and non-OA groups. There was no postoperative infection. Union of allograft was observed in all cases. The period required for union was significantly longer in non-OA groups (28.7 weeks) compared to OA groups (14.9 weeks). One block bone graft was resorbed after plantation, while all of the chip bone grafts had good union. These results suggested that graft-bone union can obtain better with chip bone than with block bone grafts.
