There are two basic techniques for tying the surgical square knot: the one-hand technique and the two-hand technique. The techniques differ in the fingers that are used. Different grips are presented as well as real time demonstrations and step-by-step guidance for each technique. Instrument tying of square knots is also demonstrated. This presentation works best when combined with face-to-face instruction and included handout.
