Embodiments of a knot pusher and methods of use thereof are disclosed, that are usable for pushing a knot formed from a suture, two limbs of the suture extending from the knot. The knot pusher comprises a distal head defining top and bottom walls terminating in a distal knot pushing surface. The distal head includes at least two side grooves defined between the top and bottom walls that extend proximally from the knot pushing surface. Each of these side grooves is operable to receive one of the limbs of suture. The distal head additionally comprises at least one suture guide coupled to the top and bottom walls for guiding the one of the limbs of suture into one of the side grooves.
