Diamond‐Unit Crisscross Mattress Suture for Double‐Row Rotator Cuff Repair: An All‐Arthroscopic Technique

Abstract This article describes the diamond‐unit crisscross mattress suture technique for double‐row rotator cuff repair using an all‐arthroscopic approach. This method combines knotted fixation at the medial row and knotless fixation, offering uniform tendon footprint coverage while reducing anchor usage. The technique is straightforward to perform and does not require additional sutures. By using a single lateral‐row anchor, it improves the contact and stability between the tendon and bone. This technique is intended for selected small‐ to medium‐sized tears, particularly those with irregular or degenerative margins.
