This study aimed to report the outcome of total hip arthroplasty (THA) with a modular femoral component in patients younger than 50 years with osteonecrosis of femoral head. 64 osteonecrotic hips in 55 patients were available for clinical and radiographic analyses at minimum follow-up of 15-years. The mean Harris hip score improved from 36 points preoperatively to 92.7 points at final follow-up. 62 (95.3%) hips demonstrated stable bone ingrowth. No hips showed loosening or required revision for aseptic loosening. Survivorship with an end point of stem revision for any reason was 93.8% and for aseptic loosening was 100% at 16.8years. We believe that cementless THA with a modular stem is a promising procedure for young and active patients with osteonecrosis of the femoral head.
