The recognition of and discussion of operative techniques for subscapularis tendon tears have lagged behind those for the posterosuperior rotator cuff. The advancement of shoulder arthroscopy has provided the opportunity to see the articular side of the rotator cuff and has led to increased recognition of subscapularis tears. Double-row fixation of the posterosuperior rotator cuff has become popular because of improved biomechanical strength, footprint restoration, and tendon healing compared with single-row fixation. Double-row fixation of the subscapularis, however, has been challenging because of the small anterior space overlying the subscapularis. Whereas the subacromial space allows freedom of movement, the limited subcoracoid space makes visualization, instrument manipulation, and knot tying more difficult. We describe a new technique for double-row fixation of the upper subscapularis footprint using a knotless technique without an additional anchor, which eases some of the aforementioned difficulties. The technique is indicated for partial-or full-thickness tears of the upper 50% of the subscapularis tendon and therefore applies to the majority of tears involving the subscapularis tendon.
