Research progress on suture and fixation approach of arthroscopic rotator cuff repair in suture-bridge technique

With advances in arthroscopic surgery, arthroscopic repair for rotator cuff tears is often used by surgeons. Surgical methods have already developed from simple single-row fixation and double-row fixation to complicated suture-bridge fixation. Although arthroscopic suture-bridge rotator cuff repair has been proposed to be advantageous over single-row and double-row fixation in biomechanical constructs, the failure of rotator cuff repair is still higher. Different suture methods of medical row anchor in arthroscopic suture-bridge technique may change the suture-tendon loading and decrease the retear of suture-tendon. And different fixation methods of lateral row anchor in arthroscopic suture-bridge technique may decrease the anchor pull-out. These will be useful to decrease the failure of arthroscopic suture-bridge technique. There will be a good outcome if optical suture and fixation approach can be chosen according to the quality and retraction of rotator cuff, suture tension and the bone quality of the greater tuberosity in arthroscopic suture-bridge technique.
