Abstract
Introduction: To evaluate the surgical outcome of the arthroscopic repair of the capsulolabral lesion using suture anchors in a large series of patients who were followed-up for mid-term. Methods: We prospectively evaluated 167 consecutive patients (age, 25±6.4 years) with traumatic recurrent anterior shoulder instability after an arthroscopic Bankart repair using suture anchors. We used three outcome measurement tools (UCLA, ASES, and Rowe scales) preoperatively and at the time of follow-up (mean, 44 months; range, 24-75 months). The recurrence rate, range-of-motion, and risk factor for postoperative recurrence were evaluated. Results: Seven patients (4.2%) had recurrent instability (1 dislocation, 2 subluxation, and 4 patients with positive anterior apprehension test). The mean shoulder scores were improved (T-test, p<0.05). One hundred and thirty patients (78%) had excellent, 29 (17%) good, 6 (4%) fair, and 2 (2%) poor scores (Rowe scale). The mean loss of external rotation was 2.0±4.08. Patients' activity increased after the surgery (p<0.001). One hundred and fifty-two patients (91%) returned to more than 90% of previous activities. The degree of glenoid defect (greater than 30%) was related with the postoperative recurrence (Gehan's test, p<0.0001). In patients with postoperative instability, the recurrent episode was less frequent and shoulder function was related with the activity level (Fisher's Exact test, p=0.029). Revision arthroscopic Bankart repair stabilized 3 out of 4 patients. Conclusion: Unlike to the previous reports on the results of the arthroscopic repair, arthroscopic capsulolabral repair using suture anchors provided satisfactory outcomes in terms of the recurrence, activity, and range-of-motion.
