Femoral osteonecrosis does not heal on its own, but the condition can be treated to provide symptomatic relief. There are stages of femoral head necrosis. Stage I and II can be treated conservatively or surgically to achieve healing, but they cannot heal on their own. In this stage, the area of femoral head necrosis is small, the blood circulation is still in good condition, and the joint surface is not damaged, so interventional surgery or medication can intervene in the process of femoral head necrosis and maintain the function of the joint as much as possible. Once the head of the femur enters the third stage of necrosis and beyond, it is irreversible and difficult to reverse, no matter what means are taken. If the femoral head has collapsed and the acetabulum is worn out, the person can only undergo joint replacement at this time. Patients with osteonecrosis of the femoral head should strictly follow the doctor’s instructions and can take treatments such as reducing weight bearing, oral medication and, if necessary, surgery to control the development of osteonecrosis of the femoral head.
