Rotator cuff tear is consensus amongst orthopaedic surgeons and physical therapists regarding rotator cuff repair rehabilitation protocols. The timing and duration of treatments and exercises are based on biologic and biomedical factors involving the rotator cuff. For approximately two to three weeks following surgery, a patient experiences shoulder pain and swelling; no major therapeutic measures are instituted in this window other than oral pain medicine and ice. All in all, those patients at risk of failure, should undergo a more conservative approach to rehabilitations. That is followed by the "proliferative" and "maturation and remodeling" phases of healing, which ensues for the following six
Rotator cuff arm, moving it outward and away from the trunk, the rotator cuff compresses the glenohumeral joint, an action known as concavity compression, in order to allow the large deltoid muscle to further elevate the arm. In other words, without the rotator cuff, the humeral head would ride up partially out of the glenoid fossa, lessening the efficiency of the deltoid muscle. The anterior and posterior directions of the glenoid fossa are more susceptible to shear force perturbations as the glenoid fossa is not as deep relative to the superior and inferior directions. The rotator cuff's contributions to concavity compression and
