Do functional outcomes and cuff integrity correlate after single- versus double-row rotator cuff repair? A systematic review and meta-analysis study.

Purpose: The purpose of this study is to perform a systematic review and meta-analysis of all available level I prospective randomized controlled trials comparing arthroscopic single-row (SR) with double-row (DR) rotator cuff repairs by both clinical outcomes and radiological re-tear rates.

Methods: PubMed, EMBASE, Google Scholar, and Cochrane databases search was done for level I RCTs comparing clinical and radiological outcomes after SR versus DR rotator cuff repair. Clinical outcomes included UCLA, ASES, Constant, WORC, and SANE scores; structural outcomes included MRI, MRA, or US.
