The knot is completed ( Fig 1L) by forming the second half-hitch using a regular one-handed tie. The black suture is passed to the other hand ( Fig 1J) to provide counter traction and to tighten the throw as the white suture is pulled away ( Fig 1K). This knot is a simple modification of the square knot.It requires an additional twist when tying the first half of the knot which makes it incredibly secure. It’s also one of the more popular knots used for jewelry making. The white (proximal) suture is picked up using the index and middle fingers ( Fig 1G), and pulled through the loops ( Fig 1H-I), assisted by the thumb simultaneously pushing the loops. The surgeon’s knot is a surgical knot used to bind suture threads. 1E), which is subsequently grasped by the ring and little fingers ( Fig 1F). The index and middle fingers are then slightly separated to release the black suture end ( Fig. A total of three loops produce a surgeon’s knot, as displayed in the figure and video, while two loops produce the standard square knot. Loops are formed around these fingers by pronating the hand to bring the thumb behind the suture ( Fig 1B), followed by supination ( Fig 1C). The black (distal) suture end is held between the index and middle fingers ( Fig 1A). This technique ( Fig 1, Video 1) is adapted from the concept of instrument tying.
