Outcomes of arthroscopic Bankart repair in collision versus noncollision athletes.

Abstract

The purpose of the study was to compare the recurrence rate of arthroscopic Bankart repair with suture anchors in collision vs noncollision athletes. Sixty-four patients who underwent arthroscopic shoulder stabilization using suture anchors for recurrent anterior dislocation were identified. Forty-three patients (22 collision and 21 noncollision) were evaluated at a minimum 24-month follow-up. The recurrence rate was reported, and functional outcomes (American Shoulder and Elbow Society, Western Ontario Shoulder Index, and Short Form 12) were evaluated. Statistical analysis was performed using chi-square test and Student's t test with a 95% confidence interval and a significance level set at a P value less than .05. The overall dislocation recurrence rate was 4.6% (2 of 43 patients); the dislocation recurrence rate in collision athletes was 9% (2 of 22 patients), and no redislocations occurred in noncollision athletes. No statistical differences existed in Western Ontario Shoulder Index score (73.5% in collision and 73.4% in noncollision athletes; P=.831), American Shoulder and Elbow Society score (91.2 in collision and 80.7 in noncollision athletes; P=.228), and Short Form 12 score (108.5 in collision and 101.2 in noncollision athletes; P=.083). Average external rotation loss was 6.8° in collision and 5.5° in noncollision athletes (P=.864). Ninety percent of collision athletes vs 95% of noncollision athletes were satisfied. Seventy-three percent of collision and 81% of noncollision athletes were able to return to sport at their preinjury levels. Collision athletes had higher recurrence rates after arthroscopic shoulder stabilization compared with noncollision athletes, but no statistical difference was found. Functional outcomes according to American Shoulder and Elbow Society, Western Ontario Shoulder Index, and Short Form 12 were similar.
