“…based on previous studies [3,10,15,16]. The 50-N load was selected to simulate the tension on the sutures tied over a cortical bone bridge in ligament-reconstruction procedures [14], while the 200-N cyclic load was chosen because it locates in the ranges of force on the ACL during level walking (169 N) [5] and the load on the ulnar collateral ligament during throwing (290 N) [4].…”

“…Several studies have evaluated the biomechanical properties of the needleless suture techniques [2,10,12,15]. Krappinger et al [12] compared the modified Prusik knot with the whipstitch, and found that the modified Prusik knot had similar mechanical properties as the whipstitch technique.…”

“…Krappinger et al [12] compared the modified Prusik knot with the whipstitch, and found that the modified Prusik knot had similar mechanical properties as the whipstitch technique. Su et al [15] proposed the modified finger-trap for securing tendon grafts, and showed that the modified finger-trap provided better biomechanical properties than the Krackow stitch. Hong et al [10] evaluated the tendon graft holding strength of the modified Prusik knot, Wittstein suture loop, and modified rolling hitch; their results showed similar elongation after cyclic loading and loading to failure.…”

“…A reliable soft tissue suture technique is essential for ligament-reconstruction surgery, because adequate fixation allows for rehabilitation programs before completion of biologic fixation in the graft tunnel [1,3,6,13,15]. The whipstitch is a common suture technique for preparing and fixing tendon grafts [14].…”

“…Several needleless grasping sutures, namely the modified Prusik knot, Wittstein suture loop, rolling hitch, modified finger-trap, and modified rolling hitch, have been proposed in recent years owing to inherent disadvantages of the previous techniques, including tendon damage caused by passing a needle, time consumption, and the potential risk of needlestick injury [7,8,12,15,17]. These needleless techniques have been shown to reduce cost, decrease exposure to needles, and shorten surgical time [7,8,10,12,17].…”

Background Numerous needleless techniques for tendon graft fixation that feature several advantages have been reported. However, there are few studies that have compared the holding strength between the needleless techniques (rolling hitch and modified rolling hitch) and traditional suture methods. Questions/purposes To compare the tendon graft-holding strength of the rolling hitch and modified rolling hitch with the Krackow stitch in an in vitro porcine biomechanical model. Methods Thirty fresh-frozen porcine flexor profundus tendons were randomly divided into three groups of 10 specimens. The experimental procedure was designed to assess elongation of the suture-tendon construct across the needleless tendon-grasping techniques and the Krackow stitch. All suture configurations were completed with a braided nonabsorbable suture. Each tendon was pretensioned to 100 N for three cycles, cyclically loaded from 50 to 200 N for 200 cycles, and then finally loaded to failure. Elongation, load to failure, and mode of failure were recorded for each specimen.
