Which symptom is most commonly associated with avascular necrosis of the hip?

Avascular necrosis (AVN) of the hip typically presents with pain in the groin, which is a hallmark symptom of this condition. The hip joint, located in the innermost part of the body, is primarily affected by AVN due to inadequate blood supply to the bone, leading to the death of bone tissue. As the condition progresses, the pain may radiate to the thigh or knee, but it predominantly starts in the groin area. This can be attributed to the anatomical location of the hip joint and the way in which pain is referred in the body.

Understanding this symptom is crucial for early diagnosis and intervention, as early treatment can prevent further joint deterioration and improve patient outcomes. Familiarizing oneself with the typical presentation of AVN, including the characteristic groin pain, is essential for those involved in orthotic and prosthetic practices.
