title: Total hip arthroplasty in the treatment of osteonecrosis of the femoral head: then and now.
abstract: The objective of this review is to summarize and analyze the survivorship and the reported results of the use of total hip arthroplasty (THA) in patients with osteonecrosis of the femoral head. In the past, THA was thought to have poor survivorship and poor clinical and radiological results in patients with this diagnosis. However, more recent reports have suggested an improvement in the survivorship, radiological results, and outcomes of THAs when performed for this condition. Surgeons have incorporated THA into their practice patterns to the point that an increasing percentage of patients with this particular diagnosis are currently being treated with it. When collapse and/or arthrosis of the necrotic femoral head are present, THA seems to be the most reliable and proven option for its treatment.
