Arthroscopic Repair of Humeral Avulsion of the Glenohumeral Ligament Lesion With Capsular Plication in the Lateral Decubitus Position

Humeral avulsion of the glenohumeral ligament (HAGL) lesions can lead to persistent shoulder instability. While rare, HAGL lesions may present as a concomitant injury following shoulder dislocation events. Traditionally, an open approach has been used to repair the inferior glenohumeral ligament and restore shoulder stability. Modern arthroscopic techniques and instrumentation have permitted a minimally invasive approach for treating HAGL lesions. While technically demanding, arthroscopic repair of HAGL lesions has demonstrated favorable outcomes with less soft-tissue disruption. The following Technical Note describes a safe and effective method for the arthroscopic repair of HAGL lesions. Our technique highlights the use of the lateral decubitus position, a 70° arthroscope, a curved anchor device, and a 90° SutureLasso device.
