Phase 1: 1 to 4 weeks after surgery, without braking, the affected limb is suspended by the neck in a forearm sling and the upper arm is kept in a neutral position at the shoulder joint. Effective analgesia was administered to ensure smooth postoperative rehabilitation exercises. Finger clenching, finger extension, wrist flexion and dorsiflexion exercises; passive shoulder joint activities such as anterior flexion, lateral external rotation, abduction 90 degree external rotation, pendulum and other movements could be performed 1 d after surgery. After 4 d postoperative period, the shoulder joint could be internally retracted, abducted and internally rotated. 3 weeks later, muscle strength training was started, such as supine deltoid training, shoulder shrugging, “chest expansion” and internal and external rotation isometric training. Phase 2: 5 to 8 weeks after surgery, the forearm sling was removed and light movements over the head could be performed, shoulder joint assistance activities such as bar gymnastics, pulley, shoulder ladder training; active activities of the shoulder joint in all directions; standing deltoid training; proprioceptive training. Phase 3. 9 to 12 weeks after surgery, start to restore normal shoulder joint activities. Focus on resistance muscle training, such as Theraband, training ball, standing position dumbbell, etc. Sports are best started gradually after 3 months postoperatively. During the patient’s exercise, introduce the role of rehabilitation exercise on joint activities and muscle tissues, and the basic requirements of rehabilitation exercise, i.e., initiative, adaptability, planning, science, and timing, to encourage patients to actively and positively carry out rehabilitation training to ensure the surgical effect. After the patients were discharged from the hospital, they were regularly followed up by telephone, and were instructed and supervised to train the functions of the affected limbs in daily life, such as using the affected limbs to carry dishes, pick up vegetables, brush teeth, tie pants, etc., so as to gradually achieve self-care.
