Step 2.

Form the First Suture Loop

The first throw of the square knot is initiated by

the tip of the left index finger that passes its free

suture end over the fixed suture end held between

the tips of the right index finger and thumb.

The tip of the left index finger begins to flex

around (arrow) the fixed suture end held by the

right hand. Note that the left hand forms the

suture loop and passes the free suture end through

the suture loop. Consequently, knot construction

can be safely accomplished without detaching

the needle from the fixed suture end.

Step 3.

Pass Index Finger Down into

The Suture Loop

As the index finger passes into the suture loop,

flexion of the tip of the left index finger

continues until the dorsal surface of its distal

phalanx contacts the free suture end held by the

left hand. After the free suture end rests on the

dorsal surface of the tip of the left index finger,

extension of the finger will begin withdrawal

(arrow) of the free suture end up through the

suture loop.
