title: Cementless total hip arthroplasty in patients with osteonecrosis after kidney transplantation.
abstract: This study was to determine the mid- to long-term survivorship of cementless metal-on-metal THA in 52 patients (74 hips) who underwent THA for osteonecrosis of the femoral head with a cementless THA. The mean follow-up was 10.2 years. The mean age at operation was 42.1 years (range, 25-62 years). The survivorship analysis with revision as the end point estimated a 96.6% chance of THA survival during 16.4 years. The average Harris hip score at last follow-up was 89.2 points (range, 74-100). Two patients (two hips) required revision surgery for extensive acetabular osteolysis at 9 years and acetabular liner dissociation at 2 years. The survival rates of cementless THA in these patients are encouraging. However, the possibility of metallic wear related complications are raising concern.
