After femoral head replacement surgery, the recovery can be promoted through exercise, but according to the patient’s degree of recovery and individual tolerance, exercise should be carried out in a gradual manner, commonly used exercise methods include muscle contraction exercises, flexion exercises, joint extension and flexion exercises, bedside standing exercises, walking exercises and so on. Femoral head replacement surgery, i.e. femoral head replacement surgery, is commonly used in the treatment of femoral head necrosis. After the surgery, the tissues around the hip joint, such as tendons and ligaments, can be prevented from adhesion through exercises, the type and intensity of which should be determined by the patient’s recovery process. If the patient recovers well, he/she can get out of bed on the second day after the surgery with the aid of a walker, and can also perform muscle contraction exercises and flexion exercises in bed. If the recovery is not good, you can do joint extension and flexion exercises in bed, and then stand and walk at the bedside as your recovery progresses. Usually, about two weeks after surgery, nearly 50% of the patients can walk without a booster or crutches, and about two months after surgery, patients with good recovery can walk long distances. However, due to individual tolerance and other factors, the individual exercise program should follow the principle of timely and appropriate amount, and should not be rushed. After femoral head replacement, patients should exercise according to their own recovery condition and under the guidance of physicians. In the process of exercise, patients should not be overly anxious to prevent excessive intensity, which may affect the postoperative recovery effect.
