Arthroscopic Suture Material and Knot Type

Abstract

The SMC knot using MaxBraid provides the strongest knot/suture combination of knots and sutures tested.

Optimization of the Racking Hitch Knot: How Many Half Hitches and Which Suture Material Provide the Greatest Security?

“…Although there are no universal conclusions regarding the suture with the best repair characteristics, braided polyester sutures often have shown higher load to failure than alternative choices [2,9,10]. Abbi et al [1] reported that knots tied with FiberWire 1 had the highest load to failure values, averaging 275.97 N. Swan et al [11] also looked at the effect of suture type on load to failure using Force Fiber TM , FiberWire 1 , and Ethibond Excel TM . Swan et al [11] observed the highest load to failure using Force Fiber TM suture across all three knots tested in their trial.…”

Swan et al [11] observed the highest load to failure using Force Fiber TM suture across all three knots tested in their trial. They observed a similar magnitude load to failure for their surgeon's knot tied with Force Fiber TM (230.1 N) as we observed for a racking hitch with one half hitch (273.2 N).…”

Differential growth on sutures of tendon cells derived from torn human rotator cuff

“…The results showed that the nondegradable polyester sutures tested (Ethibond), which are the most commonly used sutures for rotator cuff repair, 25 supported the best cell survival and growth in vitro. Microscopy images showed excellent cell morphology and alignment on Ethibond.…”

Shortcuts in Arthroscopic Knot Tying

“…5 In the search for the optimal arthroscopic knot, a number of biomechanical studies have evaluated different knot configurations and suture materials. 2,3,[12][13][14]17 Although there is no consensus regarding the ideal knot configuration or suture material, basic knot-tying principles have been identified that improve knot and loop security. Reversing the direction of half-hitches and switching the post limb between throws each increase knot security by increasing friction and internal interference.…”
