Arthroscopic subscapularis augmentation of the classic Bankart repair leads to satisfactory clinical and functional mid-term outcomes in patients with recurrent anterior shoulder instability and less than a subcritical glenoid bone loss.

Purpose: The long-term failure rate of the arthroscopic Bankart repair may reach unacceptable values, raising the need to augment this classic procedure. Arthroscopic subscapularis augmentation is the tenodesis of the upper part of the subscapularis tendon to the anterior glenoid rim. The aim of the study was to evaluate the mid-term clinical and functional outcomes of patients operated with arthroscopic subscapularis augmentation of the classic Bankart repair due to recurrent anterior shoulder instability.
