Rotator cuff repair is a common cause of shoulder pain, weakness, limitations to daily activity, and time off from work. The prevalence full thickness tears in the general population is about 20% and markedly increased after the age of 50: Patients in the seventh decade have a 50% prevalence of rotator cuff tears which increases to over 80% in patients in the eighth decade of life. The shoulder is a minimally constrained ball and socket joint. The shallow glenoid allows for a wide range of motion. Passive motion is determined by bony anatomy, ligamentous and capsular restraints, and musculotendinous structures that surround the shoulder. Shoulder motion can be grossly divided into scapulothoracic and glenohumeral motion. The scapula provides a stable base for muscle activation and load transfer. Abnormal scapular thoracic motion can affect rotator cuff and shoulder function, which increases the risk of impingement syndrome . Rotator cuff muscles provide essential balance to the glenohumeral joint via compression of the humeral head on the glenoid. The supraspinatus originates on the posterior aspect of the scapula, superior to the spine, and inserts on a footprint of the greater tuberosity of the humerus. The infraspinatus originates on the posterior aspect of the scapula, inferior to the spine, and also inserts on the greater tuberosity of the humerus.
