Effect of Acromioplasty on Postoperative Pain Following Rotator Cuff Repair

Abstract

Background: The surgical treatment of rotator cuff tears traditionally involves rotator cuff repair (RCR) with concomitant acromioplasty. However, there is some doubt as to whether acromioplasty is of value to this procedure. Questions/Purpose: We sought to evaluate whether RCR with acromioplasty provided better outcomes than RCR without acromioplasty in a cohort of more than 1000 patients. Methods: This retrospective cohort study involved 1320 patients with rotator cuff tears who subsequently received a primary arthroscopic RCR, with acromioplasty (n = 160) or without acromioplasty (n = 1160), performed by a single surgeon. Acromioplasty was performed if there was significant mechanical impingement on the rotator cuff. To assess outcomes, all patients completed a standardized, modified L’Insalata questionnaire in which they reported the level and severity of pain at rest and during activities. An examiner assessed shoulder strength and range of motion before and 1 week, 6 weeks, 12 weeks, and 6 months after surgery. Results: Patients who had RCR with concurrent acromioplasty had a greater level of pain and more frequent pain 1 week after surgery. However, at 6 months there were no differences between patients who underwent RCR with or without acromioplasty in any patient-reported outcome (level of pain with overhead activity, at rest and during sleep; frequency of pain with activity, sleep and extreme pain, difficulty of activity overhead and behind back, level of shoulder stiffness; and overall shoulder satisfaction). The postoperative re-tear rate in both groups was 13%. Conclusion: This study showed no additional benefit to acromioplasty in patients undergoing RCR.
