Arthroscopic repair is as effective as open repair for isolated Bankart lesions of the shoulder and may improve range of motion.

Patients: 60 patients (mean age, 26 y, 87% men) with traumatic anterior instability of the shoulder, no shoulder symptoms or surgery before the first traumatic dislocation, ≤4 episodes of anterior dislocation of the shoulder, no clinical evidence of multidirectional instability, and radiological evidence of ≤30% loss of substance of the humeral head. All patients underwent arthroscopy to confirm a Bankart lesion of the anterior aspect of the glenoid labrum, the absence of other capsular and tendon injuries, and the absence of glenoid fractures. Follow-up study was 100%.
