An anterosuperior rotator cuff tear as shown from the subacromial space while viewing from the anterolateral portal. There is a cuff of tissue that connects the subscapularis to the supraspinatus (asterisk). This tissue represents the “comma sign” and it is preserved throughout the repair. (Supra = supraspinatus, Subscap = subscapularis, GT = greater tuberosity, BG = bicipital groove, LT = lesser tuberosity).
