Rotator cuff injuries can be treated by minimally invasive arthroscopic shoulder surgery, which is less risky when there are no other comorbidities. The surgical risk of rotator cuff injury is related to the degree of rotator cuff injury, the patient’s physical condition, tolerance to anesthesia and other factors. Currently, open surgery for rotator cuff injury is rarely used, and rotator cuff repair surgery under shoulder arthroscope is the main treatment, and has been widely used. Surgery is less traumatic, faster recovery, and less risky if there are no other comorbidities in rotator cuff injury. However, rotator cuff injury surgery also has certain risks, such as anesthesia accidents, intraoperative injuries to nerves, blood vessels and neighboring organs, cardiac, pulmonary and cerebrovascular accidents during surgery, etc. Doctors will generally assess the patient’s situation before surgery, so patients do not have to worry too much. Any surgical treatment has risks, the size of the risk is difficult to predict, it is recommended that patients choose regular hospital treatment in order to minimize the risk.
