The 4-S modification of the Roeder knot: how to tie it

H T Sharp et al. Obstet Gynecol. 1997 Dec.

Abstract

Background: The 4-S modification of the Roeder knot may be tied laparoscopically as a single-throw knot.

Technique: It is tied by adding a fourth wrap around the suture loop and securing the loop in place with a square knot rather than a single half-hitch.

Experience: We have used this knot in laparoscopic surgeries for more than 2 years and have not observed knot slippage.

Conclusion: This modification results in a knot comparable in strength to the strongest laparoscopic multiple-throw square knots.
