Background: The purpose of this study was to compare the clinical results between the collision and contact sports, and between the arthroscopic and open methods. Methods: In the case collision sports, twenty-three shoulders(group CLA) underwent arthroscopic Bankart repair(AB method), 25 shoulders(group CLB) had modified Bankart and Bristow procedure(BB method), and in contact sports, 19 shoulders(group CTA) had AB method, 10 shoulders(group CTB) had BB method. The mean age of the patients at the time of surgery was 20.3 years old, and the mean follow-up period was 61.7 months. Indication for AB method was that the glenoid bone loss was 25% or less and we can lift up AIGHL to the articular surface. We evaluated clinical outcome by JSS score, level of return to sports activities, the recurrence rate of dislocation, satisfaction levels and complications. Results: Postoperative JSS score improved in all groups. Although almost all patients returned to sports, the rate of return to pre-injury sports activity levels, of re-dislocation and satisfaction levels in group CLA were the worst of all the groups. Satisfaction levels in group CLA was significantly worse than group CLB. Discussion: Although in the contact sports group, clinical outcomes had no significant difference between AB and BB methods, in the collision sports group, clinical outcomes in AB method were significantly worse. We think BB method is better than AB method for traumatic anterior shoulder instability in collision sports athletes.
