We describe 3 cases of an all-arthroscopic technique for repair of a humeral avulsion of the glenohumeral ligament (HAGL) lesion and the postoperative clinical outcomes. From a technical perspective, the most critical part of the surgeries was the anchor insertion at an optimal position on the humerus in order to achieve proper tension of the glenohumeral ligament. The arm-free beach-chair position, which facilitates maximum internal rotation, use of a 70 degrees angled arthroscope, and an anterior-inferior trans-subscapularis tendon portal were considered key factors to accomplish this procedure.
