Over-pointing technique: an approach to past-pointing arthroscopic knots on alternating suture posts without alternating the knot pusher

Abstract

As arthroscopic reconstructive surgery evolves, new techniques that improve operative efficiency while maintaining proven technical principles will enhance a surgeon's skill repertoire. A secure arthroscopic knot requires placing a series of reversed half-hitches on alternating posts and has traditionally involved alternating the knot-passing device between suture limbs to "past-point" each half-hitch, ensuring overall knot security. To increase the speed of knot-tying, a technical variation of keeping the knot pusher on the same suture limb throughout the knot-tying process, while still alternating posts, can be used. This technique involves alternately "pushing" and "pulling" sequential half-hitches into place. It is important to note that although conventional past-pointing is performed when "pulling" a half-hitch, it cannot be performed when purely "pushing" a half-hitch. In this article we describe a novel technique of "over-pointing" to be performed when pushing half-hitches into place. This is meant to be a complement to past-pointing by use of the knot pusher to advance the half-hitch and tighten the knot by over-riding the knot, effectively providing the equivalent of past-pointing by "pulling" the knot tight. In this way, a knot can be constructed without removing the device from the initial post strand of suture, saving time while maintaining the principles of secure knot-tying.
