A biomechanical comparison of arthroscopic sliding and sliding-locking knots

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

“…In their study, the highest load to failure values were seen with the Weston knot (168 N) [7]. Our testing setup using a Weston knot also tied with Force Fiber TM resulted in a similar load to failure of 145.2 N. However, in our study, the load to failure values for the racking hitch with three half hitches averaged 359.6 N. This is more than twice the force reported by Elkousy et al [7].…”

Although a portion of the improved performance may be attributed to the knot configuration, a possible explanation of these observed differences is that a racking hitch knot is tied with a doubled suture.…”

“…Elkousy et al [7] also tested load to failure characteristics with different knot configurations. In their study, the highest load to failure values were seen with the Weston knot (168 N) [7].…”

An in vitro analysis of the mechanical properties of 16 arthroscopic knots

“…To date, there has not been a systematic study that has examined the commonly used arthroscopic knots described in the literature and determined which knots have the best biomechanical parameters, as determined by (1) load to ultimate failure, (2) load to clinical failure (load at 3 mm elongation), (3) resistance to elongation under cyclic loads, and (4) ultimate displacement, (5) stiffness, (6) loop security (i.e., loop circumference at 5 N load), and (7) mode of failure using both absorbable and non-absorbable suture. In addition, a number of suture materials are available from which to choose.…”

Análise da resistência de fios cirúrgicos utilizados no reparo do manguito rotador

“…O fio Force Fiber ® apresentou ponto de ruptura em 279 ± 41N com o nó San Diego, 254N ± 41N com o nó Weston e 224 ± 70N com o Duncan (15) . Elkousy et al, avaliando os nós Weston, Square, Duncan e Nicky's, concluíram que todos têm resistência similar (16) .…”
