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.
