In theory, extrinsic anterolateral acromial impingement of the rotator cuff can contribute to cuff tearing. Thus, acromioplasty may be performed concomitantly with arthroscopic rotator cuff repair (ARCR). A review of recent randomized controlled trials confirms that patient long-term outcomes after ARCR is superior when acromioplasty is performed, when compared to no concomitant acromioplasty, while complication and retear rates are similar.
