Arthroscopic Repair of Humeral Avulsion of the Glenohumeral Ligament Lesion.

Humeral avulsion of the glenohumeral ligament (HAGL) is a lesion associated with anterior shoulder instability. Although uncommon, HAGL lesions are a significant contributor to shoulder pain and dysfunction and, if missed, can even be a cause of failed Bankart repair. HAGL lesions should generally be repaired surgically; however, given their low prevalence, there is no consensus on the optimal surgical approach. The purpose of this Technical Note is to describe our preferred surgical technique for the fixation of an HAGL lesion using an all-arthroscopic approach and a knotless suture anchor construct.
