For athletes of non-contact sports, we have been performing the arthroscopic Bankart procedure using TwinFix anchors since 1998. Here, we report the therapeutic results of this surgery. The subjects were nineteen patients consisting of eighteen males and one female. The age at the time of surgery ranged from eighteen to forty-two years old (mean: 27.8). Types of sport were: baseball in five cases (all were infield players); golf in three; skiing in two; volleyball in two; tennis in two; soccer in two; and others in three. Eight of the nineteen patients were at a competition level. In preoperative physical examination, anterior apprehension test and relocation test were observed in all patients, but no patients had multidirectional instability. On radiographic findings, the Bankart lesions were observed in all the patients but a small bony Bankart lesion was obtained in five patients. Regardless of the condition of instability, the residual glenoid labrum was properly detached from the scapula neck in all the patients and the arthroscopic Bankart procedure was performed using TwinFix anchors. The number of these anchors was determined based on the area of the detached glenoid labrum. The follow-up period was between two years and four years and five months (mean: two years and ten months) and the therapeutic results were evaluated according to the JOA score and JSS shoulder instability score. No patient developed a dislocation or subluxation after surgery. None of the anchors was pulled out or broken. In the postoperative range of motion, the external rotation was restricted by about 6.3 degrees on average compared to the non-affected side. Return to the original sport was permitted six months after surgery. All the patients could return to their original sport at the level before the injury one year after surgery. Excellent results were obtained without recurrent instability by the arthroscopic Bankart procedure using TwinFix anchors in athletes of non-contact sport.
