Subscapularis Tears in Large to Massive Rotator Cuff Tear

Do concomitant subscapularis tears in large to massive rotator cuff tears affect postoperative functional and structural outcomes? Background and purpose: The subscarpularis tendon is essential force maintaining normal glenohumeral biomechanics. However, there are few studies which have addressed the outcomes of tears extending to the subscapularis tendon in massive rotator cuff tears. The purpose of this study was to assess the clinical and structural outcomes of arthroscopic reapair of massive rotator cuff tears involving the subscapulrais.
