Osteonecrosis of the femoral head is a debilitating condition characterized by progressive degeneration of bone that eventually leads to collapse of the femoral head in the majority of patients. Femoral head-sparing procedures have been more successful in pre-collapse stages of osteonecrosis than in post-collapse stages, although some patients with early post-collapse disease have had no additional progression of the disorder. Nevertheless, the effects of collapse on the articular cartilage are not well understood, and radiographic staging of femoral head collapse does not address the condition of the articular cartilage.
