Schematic surgical procedure for double rip-stop technique with medial row knots (DRSK). a) Two screws (BioComposite Corkscrew FT Anchor 4.5 mm, loaded with No. 2 FiberWire; Arthrex, Naples, Florida, USA) were used for the medial row and the sutures perforated the tendon at 13 mm to 15 mm medial to the end. b) One suture limb from each anchor passed the tendon to form a loop, followed by c) passing the sutures laterally on the articular surface, where the first rip-stop was formed. d) The suture limb then passed through the loop to form the second rip-stop. c) On the articular surface of the infraspinatus tendon, as well as on the e) bursal surface, two rip-stops were made, respectively. e) Two square knots were tied for each medial anchor. f) Two anchors (BioComposite Pushlock 3.5 mm; Arthrex) were used for the lateral row with a knotless technique. g) The enlarged final fixation configuration of DRSK. h) Side view of the configuration of DRSK. Blue arrows denote the rip-stop of the articular side, and black arrows denote the rip-stop of the bursal side.
