For rotator cuff tears, the treatment mainly includes conservative treatment and surgical treatment, as follows: a. Conservative treatment. Mild rotator cuff tears, where the patient does not have clinical symptoms of weakness and the shoulder joint activity is not affected, can be treated conservatively. Short-term immobilization of the upper extremity reduces rotator cuff tissue tension and promotes repair. If it is a refractory tear, it is difficult to repair through arthroscopic surgery and only conservative treatment can be considered. By exercising the strength and power of the muscles around the rotator cuff joint to partially replace the function of the rotator cuff tissue, the patient can still adhere to normal life, but cannot exercise strenuously. Second, surgical treatment, common rotator cuff tears cause pain, limited activity and weakness symptoms, and surgical treatment needs to be considered. Usually minimally invasive arthroscopic surgery is used clinically to repair the rotator cuff tissue, which can restore the function of the rotator cuff. Patients are provided with postoperative shoulder rehabilitation training to restore the range of motion of the shoulder joint.
