Adhesions three months after rotator cuff injury can be recovered with physical therapy and strengthening exercises. Severe cases can also be treated by arthroscopic release. After rotator cuff injury surgery, the injured upper limb needs to be suspended and braked to promote the healing of the injured rotator cuff, and adhesion of the shoulder joint will occur after prolonged braking. Shoulder muscle stiffness can be improved through shoulder hot compress, massage and acupressure to promote functional recovery. Functional shoulder exercise is an important exercise to promote the recovery of adhesion. In the early stage of exercise, you can choose to passively move the shoulder joint and exercise with pain, and with the recovery of shoulder joint function and reduction of adhesion, you can change to active exercise, such as climbing wall movement, hanging bar and other exercise methods. If the adhesion of shoulder joint is serious and cannot be recovered after a long time of exercise, the adhesion band can be loosened under arthroscope. If adhesion occurs in the joint three months after rotator cuff injury, it is recommended that the patient go to the hospital and receive regular treatment under the guidance of the doctor.
