This will depend on several factors, including your level of strength before the operation and the severity of the rotator cuff tear. Some period of immobilization of the shoulder joint is needed to protect the newly placed sutures from being disrupted. After one to two weeks, physical therapy begins. Initially, the therapy is gentle so as not to affect the rotator cuff repair. After four to six weeks, more active lifting with the arm begins. Several months after the rotator cuff repair, physical therapy will become more intense in an effort to strengthen the rotator cuff muscles. Complete recovery usually requires at least four to six months.
