摘　　要：Objective： To study retrospectively 20 hip revison patients treated by cementless total hip arthroplasty with structural allograft. Methods： Twenty patients suffering from aseptic loosening of an uncemented cup complicated by a large defect underwent cementless total hip arthroplasty with structural allograft and were followed up for at least 5 years. Clinical results were evaluated by Harris score and leg length measurements. Radiographic analysis included implants migration, graft absorbance, osteolysis and liner wear. Results： No cup loosening or graft reabsorption was found at final follow-up. Clinical improvements in pain and functional status were demonstrated during the follow-up period. The mean Harris hip scores improved from 29 preoperatively （range 20-41） to 81 postoperatively （range 73-89）. Conclusion： Our study shows that cementless total hip arthroplasty with allograft is a good way for massive defect in aeetabular bone stock.
