Eight Level I and II publications (6 RCTs and 2 prospective cohort studies) were included in this meta-analysis which compared double-and single-row arthroscopic rotator cuff repair. The pooled results indicated that functional outcomes measured were superior in those who had received double-row repair, however this was primarily in patients presenting with large tears. Postoperative cuff integrity and a reduced risk of partial-thickness retear were also associated with double-row repair. For small tears that were less than 3 cm there were no differences in outcomes between double and single row repairs.
