Suture anchors are superior to transglenoid sutures in arthroscopic shoulder stabilization.

摘要

PURPOSE: We retrospectively compared 2 groups of high-demand patients with post-traumatic anterior shoulder instability to determine whether arthroscopic stabilization was superior with transglenoid suture or suture anchors. METHODS: In a retrospective comparative study we investigated the results of 246 high-demand patients, with post-traumatic anterior shoulder instability, who underwent arthroscopic capsulolabral reconstruction: 165 (mean age, 27.5 years; mean follow-up, 80 months) were evaluated after treatment with transglenoid sutures, and 81 (mean age, 26.6 years; mean follow-up, 27 months) were treated with suture anchors in a consecutive period. We compared both techniques with regard to recurrence rate, postoperative complications, range of motion, sport activity, work, and patient satisfaction. RESULTS: In the anchor group recurrent dislocation after surgery occurred in 7 patients (8.7%), all within 18 months postoperatively. This finding was significantly (P = .009) better than that in the transglenoid group, in which recurrent postoperative dislocation occurred in 57 patients (34%), in a period of 0 to 115 months after surgery. Postoperative complications were seen in 4 of 81 patients in the suture anchor group, whereas a significantly (P = .01) higher rate was found in the transglenoid suture group, with 36 complications in 35 of 165 patients. CONCLUSIONS: The data presented in this study suggest that the modern suture anchor technique results in a better outcome after shoulder stabilization, with fewer complications and lower recurrence rates, than the transglenoid repair. We conclude that the suture anchor technique should be a preferred method for arthroscopic shoulder stabilization surgery. LEVEL OF EVIDENCE: Level III, retrospective, comparative therapeutic study.
