FIGURE 10. (Continued)

 Place the arthroscopic knot pusher on the thumb of the dominant hand.
 Hold the loop limb in the non-dominant hand (Fig. 10A ).
 Measure four fingerbreadths from the aperture of cannula along the post with the dominant hand
(Fig. 10B ).
 Position your dominant hand at this distance and wrap the remainder of the post around the ring
finger and small finger of the dominant hand (Fig. 10C ).
 Throw a half hitch (overhand) with the loop limb (non-dominant hand) around the post limb
(dominant hand) (Figs. 10D , E , F , G , H , I ).
 Thread the loop limb through the lumen of the knot pusher. Grasp the distal end of the loop limb
with your nondominant hand (Fig. 10J ).
 Maintain tension on both the loop limb and the post limb.
 Use the arthroscopic knot pusher, held in the dominant hand, to slide the knot through the cannula
and down to its final position (Figs. 10K , L , M ).
