Arthroscopic Suture-Bridge Repair of the Subscapularis Tendon—“Inside and Outside the Box” With Preservation of the Comma Sign

The subscapularis muscle and its tendon are of major importance in the kinematics of the glenohumeral joint. Therefore, a diligent repair of subscapularis tears is essential. We describe our reliable standardized arthroscopic suture bridge technique to repair subscapularis tears under intra- and extraarticular visualization and with preservation of the “comma sign.” This technique provides excellent exposure of the subscapularis tendon, allows its complete release in the subcoracoid space and ensures a safe and stable repair.
