Shoulder instability can be classified according to its direction—anterior, posterior, or multidirectional; its magnitude—dislocation, subluxation, or micro-instability; and its etiology—traumatic or atraumatic. This chapter focuses on the management of traumatic anterior shoulder instability without associated glenoid bone loss. Surgical treatment requires consideration of clinical history, risk factors for recurrence, and injury patterns. Recurrent instability is generally the primary indication for surgical intervention, while surgical management of first-time dislocations remains debated but is considered in patients with a high risk of recurrence. Injury patterns, particularly Bankart lesions and Hill-Sachs defects, play a crucial role in determining the choice between conservative and surgical treatment, as well as the selection of specific surgical techniques such as remplissage. Our preferred surgical approach is an arthroscopic Bankart repair with capsular shift using a knotless anchor technique with vertical mattress stitches and suture tape. Hill-Sachs remplissage is added when a considerable bone defect is present. Arthroscopic Bankart repair is generally considered a safe procedure with a low overall complication rate. However, surgeon awareness is crucial to prevent unsatisfactory outcomes and manage potential complications such as postoperative stiffness, infection, nerve injuries, chondrolysis, and osteoarthritis. Clinical results are generally favorable, with proper patient selection and evolving techniques, such as the addition of remplissage, having shown promising results in reducing recurrence risk and improving functional outcomes. Postoperative functional scores, range of motion, and return to sports rates are encouraging, particularly for the young and active patient population typically affected by this condition.
