After surgery for a rotator cuff tear, it takes about three months to fully recover from the surgery with aggressive treatment. Surgery for rotator cuff tears is mainly for those cases where the rotator cuff injury is very serious and affects the patient’s normal shoulder lifting function. The surgery is usually performed under good anesthesia and is usually performed using a shoulder arthroscope to repair and reconstruct the rotator cuff. After surgery, the affected limb must be strictly suspended for protection in the early stage, and the shoulder must not be lifted prematurely, otherwise the tendon may be ruptured again.
