Outcome of Physiotherapy Treatment on a 28-Year-Old Male Diagnosed With Avascular Necrosis.

Avascular necrosis (AVN) of the femoral head is a chronic condition that primarily affects patients under the age of 40. While the precise etiology of AVN remains unknown, the condition is defined by a vascular insult to the femoral head's blood supply, which can cause the femoral head to collapse and then undergo degenerative alterations. As the condition worsens, the articular surface may collapse depending on how much of the femoral head is affected.
