How long does physiotherapy take to work for avascular necrosis of the hip?

Physiotherapy for avascular necrosis of the hip may ease movement and improve support over weeks, but it cannot restore damaged bone and must follow your specialist’s weight-bearing advice. The plan depends on the stage of the condition, pain, hip stability and whether a procedure or other treatment is being considered.

A physiotherapist may teach safe walking strategies, use of a mobility aid, gentle range-of-motion work and strengthening that does not overload the hip. The purpose is to preserve function and reduce avoidable strain while your orthopaedic team monitors the joint. Pain relief alone does not show whether the bone condition is changing.

Follow the advised limits on weight bearing and do not add impact exercise, deep bending or long walks without clearance. Use the prescribed aid correctly and report changes in walking tolerance. Keep appointments with the clinician managing the hip, because rehabilitation needs to change if imaging, symptoms or treatment plans change.

Arrange prompt review for rapidly increasing hip or groin pain, a new limp, inability to bear the advised load, or a sudden loss of hip movement. Seek urgent care after a fall with severe pain or inability to stand. New calf swelling, chest pain or breathlessness also requires urgent assessment.

Ask how much weight the hip can safely take, which exercises are appropriate, whether an aid is needed, how progress will be monitored, and what symptoms should trigger an earlier orthopaedic review.
