Comparison of Surgical Techniques for Anterior Shoulder Instability

Study objectives Primary Objective To compare the clinical and functional outcomes of arthroscopic Bankart repair and Dynamic Anterior Stabilization (DAS) in patients with chronic anterior shoulder instability and subcritical glenoid bone loss (10-20%). Secondary Objectives To evaluate postoperative shoulder stability, recurrence of instability, functional outcomes, complications, and return to daily and sports activities following the two surgical techniques. To assess the relationship between the extent of glenoid bone loss and postoperative clinical and functional outcomes. To identify clinical and morphological factors associated with postoperative outcomes and recurrence of anterior shoulder instability. We evaluate every patient at 1 month, 3 months, 6 months, 12 months, and 24 months. For evaluation, the Constant Shoulder Score, ASES Score, Visual Analog pain scale, and Oxford instability score
