Abstract

Objective: This study aimed to report the outcome of total hip arthroplasty (THA) with an extensive
hydroxyapatite (HA) coating for the fixation of a tapered femoral stem (Corail) in patients younger
than fifty years with osteonecrosis of the femoral head.
Subject and method: Seventy-four osteonecrotic hips in fifty-eight patients were available for
clinical and radiographic analyses at minimum follow-up of 10 years and at maximum follow-up 12
years.
Results: The mean Harris hip score improved from 41.68 ± 21,78 points preoperatively to 98.82 ±
2.29 points at final follow-up. Seventy-four (100%) hips demonstrated stable bone ingrowth. No hips
showed loosening or required revision for aseptic loosening.
Conclusion: We believe that cementless THA with a Corail stem is a promising procedure for young
patients with osteonecrosis of the femoral head.
