What this Trial Is About
This clinical trial will determine the outcome trajectories of common surgeries (arthroscopic Bankart repair with remplissage of a Hill-Sachs lesion, open Bankart, Latarjet) with post-operative rehabilitation and identification of prognostic factors among patients with acute or recurrent anterior shoulder instability with subcritical bone loss. The results of the study assist in optimizing time to return to military duty, work and sports, and patient-reported physical function for military personnel and civilians with traumatic anterior shoulder instability and 10-20% glenoid bone loss. This study will provide a critical clinical advancement of a previously unaddressed and common clinical scenario.
