Purpose: To analyze the clinical results of cementless total hip arthroplasty (THA) for the treatment for osteonecrosis of the femoral head in renal transplant recipients.
Materials and Methods: Twenty-one cementless THA were performed in 15 renal transplant recipients with advanced osteonecrosis of the hip. The average interval from the transplant to arthroplasty was 43 months (range, 7-122 months). The mean age at the time of arthroplasty was 35 years (range, 25-58 years). The average preoperative Harris hip score was 40 points (range, 31-57 points). The mean follow-up period was 45 months (range, 24-101 months).The articulations were metal-on-polyethylene bearing in 1 case, metal-on-metal in 6 cases, and ceramic-on ceramic in 14
cases.
Results: The average postoperative Harris hip score was 91 points (range, 82-94 points), and there were no problems such as wound healing or infections despite the immunosuppressed state. Radiographically, there was one case of femoral and acetabular osteolysis, which had used metal on polyethylene articulation, 80 months after surgery. There was neither aseptic loosening nor dislocation after an average 45 months. Heterotopic ossification was detected in 1 case.
Conclusion: The early results of a cementless THA in this young group of renal transplant recipients is encouraging.
