The Subscapularis Interlocking Stitch for the Arthroscopic Treatment of Subscapularis Tendon Tears at the Shoulder

Abstract Restoration of subscapularis function is essential for long-term maintenance of good clinical results for both traumatic and nontraumatic rotator cuff tears. The anatomic repair of partially and completely torn tendons from the footprint at the lesser tuberosity is the goal of surgical repair. The described technique, with a combination of an interlocking stitch and additional mattress sutures using a double-loaded suture anchor, provides reduction of the retracted tendon, sufficient pullout strength, and compression of the tendon to the footprint to facilitate healing.
