The SMC knot--a new slip knot with locking mechanism.

A new slip knot for arthroscopic surgery, the SMC knot, is described. By pulling the post strand, a self-locking loop is created. By tensioning the loop strand, the self-locking loop creates a snug knot without sliding backward. The SMC knot is simple and has a low profile. With a nonabsorbable suture, it provides great knot security.
