Avascular Necrosis (cont.)

Avascular Necrosis Prognosis

The underlying cause as well as the amount and location of bone affected by avascular necrosis to some degree determine the outcome. Larger areas of avascular necrosis often cannot be repaired by joint-preserving methods and ultimately joint replacement is necessary.

When an underlying disease or condition is the cause, optimal treatment of that disease or condition can decrease the chances of worsening the avascular necrosis or involvement of other areas of bone.
