We sought to compare success and re-tear rates of surgically treated full-thickness tears of the rotator cuff in men and women older than 18 years of age to develop a guideline intended for orthopedic surgeons and other health care providers who assess, counsel and care for these patients. We searched Medline, Embase and Cochrane databases through to Apr. 20, 2021, and included all English-language randomized trials comparing single-row versus double-row fixation via arthroscopic approaches; latissimus dorsi transfer (LDT) versus partial rotator cuff repair, lower trapezius transfer (LTT), and superior capsular reconstruction (SCR); and early versus late arthroscopic rotator cuff repair for traumatic tears. We also considered observational studies comparing LDT with LTT and partial repair and studies comparing early versus late treatment of traumatic rotator cuff tears. Outcomes of interest were functional outcomes, pain outcomes, and re-tear rates associated with these interventions. We rated the quality of the evidence and strength of recommendations using the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) approach. This guideline will benefit patients seeking surgical intervention of full thickness rotator cuff tears by improving counselling on surgical treatment options and outcomes. It will also benefit surgical providers by expanding their knowledge of various surgical approaches. Data presented could be used to develop frameworks and tools for shared decision-making.
