Most patients with advanced disease (stage III and above) require total hip arthroplasty. Total hip arthroplasty provides excellent pain relief for many years, although most young patients require repeat surgery. With high failure rates (10-50% after 5 years), patients with AVN will probably need a second total hip arthroplasty during their lifetime.

Cheung et al reported excellent long-term survival of cementless total hip arthroplasty for managing AVN of the hip. In their review of 182 total hip arthroplasties, 117 of them for AVN, 19.1- year survival was 97.1% for AVN patients and 96.2% for non-AVN patients. [36]
