Does total hip replacement treat avascular necrosis of the hip?

Avascular necrosis occurs when reduced blood supply damages the femoral head, the ball at the top of the thighbone. Early disease may be managed with options aimed at protecting the joint, but collapse can lead to arthritis, stiffness and persistent pain. Replacement removes the damaged ball and reshapes the socket with artificial components, addressing the failed joint rather than restoring its original blood supply.

Ask an orthopaedic specialist to stage the condition using your symptoms, examination and imaging. Mention steroid exposure, alcohol use, previous injury or other medical conditions because these can affect assessment and treatment planning. Before and after surgery, use the recommended walking aid, protect the hip as directed and complete rehabilitation exercises.

Arrange review when groin or hip pain, stiffness or limping is worsening, even if the symptoms began gradually. After surgery, urgent advice is needed for sudden severe pain, a shortened or rotated leg, wound drainage, fever, calf swelling or breathing difficulty.

Ask whether the femoral head has collapsed, whether joint-preserving treatment remains suitable, and why replacement is being recommended. Discuss implant choices, movement precautions, rehabilitation milestones and management of the underlying risk factors.
