Rotator cuff injuries have traditionally been managed by either single-row or double-row arthroscopic repair techniques. Novel and more complex single-row methodologies have recently been proposed as a biomechanically stronger alternative. However, no rigorous meta-analysis has evaluated the effectiveness of complex single-row against double-row repair. This meta-analysis aims to evaluate clinical outcomes in patients with full-thickness rotator cuff injuries treated with both simple and complex single-row, as well as transosseous-equivalent double-row procedures. An up-to-date literature search was performed using the pre-defined search strategy. All studies that met the inclusion criteria were assessed for methodological quality and included in the meta-analysis. Pain score, functional score, range-of-motion and Re-tear rate were all considered in the study.Abstract
