Arthroscopic Knot Tying in Shoulder Repair Surgery

Locking, Jamming, and Ratchet Mechanisms of Sliding Surgical Knots Topologically Revisited

“…Jamming loop knot [34] Jamming [18] Sliding a These knots have previously been classified variously b Also known as modified midshipman's hitch [39], and taut-line hitch [11] c These knots have only one turn of the working end around the standing part Fig. 5 The 11 previously alleged lockable (A-E), ratchet (F-J), or jamming (K) knots that turned out to be purely sliding knots that do not lock or jam.…”

“…Development of such understanding is hampered by inconsistent, or even controversial, use of terms, such as ''locking,'' ''jamming,'' and ''ratchet'' in the categorization of knots [see ''Glossary Box''] [4,7]. Thus, it is unclear whether Nicky's knot and the Giant knot are ratchet or lockable sliding knots, and whether the Tennessee Slider and Field knot are locking or purely sliding knots [2,4,[7][8][9][10][11][12][13]. Likewise, the HU knot, Vale knot, and Triad knot were claimed by their originators to be lockable knots but they seem to lack any internal locking mechanism, and the Dundee knot, which obviously features a locking mechanism, was called a jamming knot [14][15][16][17][18].…”

Comparative study of knot performance and ease of manipulation of monofilament and braided sutures for arthroscopic applications

“…This instrument is recommended by Burkhart for rotatorcuff repair [4]. Eugene Wolf's hangman knot-tying technique as described by Snyder was used for tying the Duncan knot and the Snyder knot [9]. The knots were tied around a 1.6 cm-diameter rigid plastic rod (5 cm circumference) made from polytetrafluoroethylene (TEFLON) with a low friction surface and mounted in an Arthrex "wooden shoulder" arthroscopy practice box (Arthrex, Naples, FL, USA).…”
