Abstract
From March 1992 to November 1998, 57 patients sustained 58 acute, initial, traumatic anterior shoulder dislocations at the United States Military Academy. Six patients selected nonoperative treatment. Three patients underwent primary open repair after diagnostic arthroscopy revealed no Bankart lesion amenable to repair with the bioabsorbable tissue tack. The remaining 48 patients with 49 anterior dislocations were treated with arthroscopic primary repair. There were 45 men and 3 women with an average age of 20 years (range, 17 to 23) and an average follow-up of 37 months (range, 24 to 60). The average Rowe score was 92 (range, 30 to 100). The average single assessment numeric evaluation patient rating was 95.5% (range, 50% to 100%). The average Short Form-36 score (physical function) for the stable shoulders was 99 (range, 95 to 100). Forty-three shoulders remained stable (88%). There were six failures (12%). Factors associated with failure included a history of bilateral shoulder instability, a 2+ sulcus sign, and poor capsulolabral tissue at the time of repair. All patients with stable shoulders returned to their preinjury levels of athletic activity. With follow-up of 5 years, we have observed significantly better results compared with nonoperative treatment in young, active adults at the United States Military Academy.
