Abstract:
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 acetabular bone stock.
