Subscapularis Tears: Arthroscopic Repair of the Forgotten Rotator Cuff Tendon

Despite being the largest rotator cuff tendon of the shoulder, the function and clinical relevance of subscapularis pathology has been largely ignored in the literature. Although more recent studies have focused on subscapularis tears, all have reported on techniques of open repair. The advent of arthroscopy and arthroscopic repair techniques has opened new frontiers for the diagnosis and repair of torn rotator cuff tendons, including the subscapularis. In this article, the authors review the senior author's surgical rationale, technique, and preliminary results of arthroscopic subscapularis repair.
