This ovine cadaver biomechanical study tests whether double-row rotator cuff repair (arthroscopic Mason–Allen stitches laterally + horizontal mattress stitches medially) outperforms single-row repair under cyclic and ultimate loading, and whether suture material (braided polyester vs. polyblend polyethylene) affects construct strength.
When planning rotator cuff repair, prioritize construct configuration over suture brand: double-row fixation with a Mason–Allen/medial mattress stitch pattern provides substantially better cyclic fatigue resistance and shifts failure mode from tendon pull-through to suture breakage.
In degenerated tissue where pull-through is the chief concern, a second medial anchor row — not a premium suture. Is the more impactful upgrade.
