Successful surgery can only be combined with a well-designed postoperative rehabilitation program to obtain the most ideal results. 1.On the day after surgery: Place the hip joint in a mild external booth with a pillow between the knees, or use a thong shoe to prevent the affected limb from rotating so that the toes face upward. Use lower limb intravenous pump or massage both lower limbs to promote blood circulation; use analgesic drugs appropriately to reduce pain stimulation and ensure patients rest; 2. Day 1 after surgery: ① Encourage patients to breathe deeply and cough to prevent lung infection; ② Active ankle flexion and extension exercises, repeat 50-100 times/group, 4-6 groups per day; ③ Isometric contraction of quadriceps and gluteus (alternately tense and relax muscles), repeat 50-100 times/group, 4-6 groups per day ③ Isometric contraction of quadriceps and gluteus (alternately tensing and relaxing the muscles), repeat 50-100 times/group, 4-6 groups per day; ④ In supine position, stretch the affected hip flexors by flexing the opposite hip joint; ⑤ You can lie in bed semi-recumbent appropriately, not more than 30 minutes each time; ⑥ After the drainage tube is removed, start to move out of bed under the guidance of the physician or rehabilitation teacher, and practice standing with a walker or holding a double crutch (please consult the surgeon when to put weight on the affected limb). 3.Day 2~3 after surgery: practice walking on the basis of the above exercises, move the walker or double crutches forward first, then move the body forward, then lift the affected limb, let the heel hit the ground first, then gradually put the whole foot flat on the ground, and finally move the healthy side limb; 4.Day 3~4 after surgery: perform forward flexion, back extension and abduction exercises of the affected hip in the standing position, 10-15 times/group for each movement, 4-6 groups per day; pay attention to the movements The amplitude should be increased slowly, and the knee should not be higher than the waist when flexing the hip (flexing the hip more than 90°), and avoid inward movement; 5. 7~10 days after surgery: You can increase the practice of going up and down the stairs, with the assistance of others, and follow the principle of “going up the stairs to the healthy limb first, and going down the stairs to the affected limb first”; 6. 2~3 weeks after surgery: In addition to the above functional exercises, gradually increase the amount of exercise. 6.2~3 weeks after surgery: In addition to the above functional exercise, gradually increase the amount of exercise, if possible, you can practice in situ bicycling, maintaining a speed of 15~20km/h, in order to ride a bike with a sense of fatigue.
