Background: The purpose of this study was to report the clinical outcomes of arthroscopic stabilization for recurrent anterior glenohumeral instability in basketball players.
Methods: Subjects consisted of 39 basketball players who underwent arthroscopic stabilization for recurrent anterior glenohumeral instability from 2004 to 2010. There included 18 males and 21 females with an average age of 21.7 (14-34) years old. All patients underwent arthroscopic Bankart repair using suture anchor technique, which included 16 bony Bankart repairs, one capsular repair and one HAGL repair. In addition, arthroscopic iliac bone grafting with capsulolabral reconstruction was performed in 5 patients and Hill-Sachs remplissage in one patient. Rotator interval closure was performed in all except 2 patients. The causes of first time dislocation and clinical outcomes were evaluated retrospectively.
Results: Sixty-nine percent of the first time dislocations occurred during basketball play. The cause of the injury was during contact play such as competition for loose or rebound balls, mostly as well as during non-contact play: shoot blocks; pass cuts; over-handed passes. Postoperative Rowe score was significantly improved from 27 to 98, as well as JSS-SIS being improved from 50.4 to 91. 26 in patients who we could check by questionnaire had returned to basketball. However, 2 patients (5.2%) suffered re-injury during Basketball play and one patient underwent revision surgery.
Conclusion: Arthroscopic stabilization for recurrent anterior glenohumeral instability in basketball players yielded successful outcomes. The ratio of dislocation during contact play was almost equal to that during non-contact play.
