Biomechanical and Clinical Comparison of Suture Techniques in Arthroscopic Rotator Cuff Repair

* Numerous single-row and double-row repair suture techniques are used in performing arthroscopic rotator cuff repair. However, to our knowledge, there remains no clear consensus on the optimal suture technique for rotator cuff repair. * Biomechanical studies have found double-row fixation to be stronger than single-row fixation techniques and massive cuff stitch or modified Mason-Allen techniques to have the strongest fixation of single-row techniques. * Some clinical studies have shown improved healing rates for double-row repair suture techniques for larger tear size (>3 cm), but the majority of clinical studies have shown no difference in outcome scores among different suture techniques. * Obtaining healing in rotator cuff repair is multifactorial. Suture technique is one of many elements that may play a role in obtaining rotator cuff healing and successful clinical outcomes.
