HAGL lesion occurring after successful arthroscopic Bankart repair.

Recurrent traumatic anterior shoulder instability following surgical repair may be associated with implant failure and an array of capsulolabral pathology including separation of the labrum (Bankart lesion), humeral avulsion of the glenohumeral ligaments (HAGL lesion), and capsular rupture. We detail a previously unreported case of a HAGL lesion occurring in a shoulder with an intact arthrosopic Bankart repair following an additional traumatic event. Anatomic repair of this subsequent injury resulted in an excellent outcome. The patient returned to his high-demand ski racing activities without any shoulder limitation.
