Practicing knee extension is as important or even more important as flexion. Early pain is normal, not because of pain and not lose activity, the best practice period (within one week after operation), and affect the function of knee joint. The purpose of postoperative rehabilitation is to restore the function and self-care ability of patients by early functional training.

Ankle pump action: after the onset of anesthesia can begin foot and ankle flexion and extension activities, each 2 to 3 minutes, every hour of 2 ~ 3 times.

Exercise of the four part of the femoral head: after the operation, the first day of the beginning of the exercise of the femoral head to maintain muscle tension in the four muscles of the head of the group of second. Try to dorsiflexion of the ankle, knee extension do leg action, for 5 seconds, 5 seconds to relax and repeat, until the thigh muscle fatigue.

Knee extension exercise: the lower limbs straight, as the exercise of the four shares of the stock, the legs lifted from the bed more than 10 cm, to maintain for 5 ~ 10 seconds, slowly put down, repeat this action until the thigh fatigue. Can do straight leg exercises held in the sitting position, the contraction of the thigh muscles, the knee extension and keep 5 to 10 seconds.

Walking frequency, step distance and speed should be uniform. When the muscle strength and endurance are increased, the walking time can be prolonged.

Up and down stairs
