The subscapularis muscle, which is the strongest muscle of the rotator cuff, plays important roles in shoulder biomechanics and stability. The emergence of a significant percentage of subscapular tendon tears in rotator cuff tears with advancing arthroscopic techniques has brought the importance of subscapular repair to the agenda along with different dynamics to the arthroscopic perspective. Patient training will reduce postoperative patient morbidity in addition to physical examination, imaging, and medical and surgical approaches to the treatment.
