“…Ease of knot placement is to advance the knot along the post using minimal force. 21,23,26,33,38,44,46,49,69,70,78 A recent study 79 on biomechanical characteristics of 9 arthroscopic sliding knots indicated the Dines knot as the best knot to place, requiring less force in forward and backward sliding, the Nicky and Tuckahoe knots as superior in all loop security characteristics, and the Tennessee as the best in knot security and knot mass. 21,22 Knot security refers to slip resistance under distractive load once the knot is completed and locked with successive half-hitch throws.…”

Most arthroscopic rotator cuff reconstruction techniques require a method of securing the tendon to the bone to obtain a stable construct. The available options include knotless technology and suture welding, but the most common method uses suture anchors and knots. Tissue quality, surgical technique, repair material, and tension overload influence the stability of tissue repair. Arthroscopic knots are technically demanding because they are tied through cannulas with long-handled knot pushers. The strength of the repair is also influenced by the suture material used. In this study, we review the state-of-the-art of arthroscopic knots and suture materials being used for arthroscopic rotator cuff repair.

“…After adding three RHAPs, the knot security will depend mostly from the half‐hitch throws. Most of them are not significantly different in load to failure and clinical use . However, loop security of initial sliding locking knot without RHAPs is different significantly between each knot types .…”

“…In arthroscopic surgery, strong repair construction relies on several factors. Arthroscopic knot is one of the most important factors to determine the outcome . The ideal arthroscopic knot should have optimal loop and knot security, low knot profile, easy to tie, and low incidence of premature or unintended locking.…”

“…Loop security of a sliding knot originates from its ability to resist backsliding when tension is released on the post strand after locking is confirmed by pulling the non—post limb. Knot security refers to the strength of the completed knot after it is locked with successive three reversing half‐hitch throws …”

“…Most of them are not significantly different in load to failure and clinical use . However, loop security of initial sliding locking knot without RHAPs is different significantly between each knot types . Success of a sliding locking knot depends on the initial sliding knot that can inherently maintain under tension without slack until it is seated by subsequent locking half‐hitches .…”

There are many types of sliding knots and suture materials used in arthroscopic surgery. The purposes of this study are (i) to evaluate the loop security of standard sliding knots when using different types of high-strength suture materials and (ii) to compare the loop security of a new sliding knot (Chula knot) to other standard sliding knots. Four configurations of sliding locking knots (Weston, SMC, Tennessee and Chula knots) were tied using three commonly used suture materials: MagnumWire, Hi-Fi, and FiberWire. The suture loops were mounted on two metallic hooks of the universal testing machine. Then, the suture loop was pulled apart until failure. The Weston knot demonstrated the greatest load to failure in all suture materials. By using MagnumWire, the load to failure was as follow: Weston 53.2 N, Chula 48.8 N, SMC 39.2 N, and Tennessee 29.3 N. By using Hi-Fi, the load to failure was as follow: Weston 58.8 N, Chula 51.5 N, SMC 38.1 N, and Tennessee 28.7 N. By using FiberWire, the load to failure was as follow: Weston 38.8 N, Chula 29.7 N, SMC 23.2 N, and Tennessee 21.9 N. Weston knot has the highest loop security in all suture materials. Weston-HiFi combination demonstrate the strongest loop security. Conversely, the weakest combination is Tennessee-FiberWire. Chula knot has similar properties to other commonly used arthroscopic sliding knots. Our findings indicate that surgeons should be careful in selecting proper knot-suture combinations. © 2016 Orthopaedic Research Society. Published by Wiley Periodicals, Inc.
