Snyder's knot (SxS//SxS//S) is another variation of the Revo knot (26 ). It consists of two reversed half
hitches on an identical post followed by post switching and two reversed half hitches followed by a post
switch with an additional half hitch.

 Throw an overhand loop around the post (Fig. 18A ).
 Pull the loop into the joint with the knot pusher on the loop limb (Fig. 18B )
 Withdraw the knot pusher while maintaining tension on the post limb.
 Throw an underhand loop around the same post (Fig. 18C )
 Pull the loop into the joint and seat the knot with the knot pusher. Once the two hitches are
seated, past-point to cinch the knot down (Fig. 18D ).
 Switch posts and throw an overhand loop around the new post (Fig. 18E ).
 Pull the loop into the joint, seat the knot with the knot pusher, and past-point to cinch the knot
down (Fig. 18F ).
 Next, throw an underhand loop around the post (Fig. 18G ).
 Pull the loop into the joint, seat the knot with the knot pusher, and past-point to cinch the knot
down (Fig. 18H ).
 Switch posts and throw an overhand loop around the new post (Fig. 18I ).
 Pull the loop into the joint, seat the knot with the knot pusher, and past point to cinch the knot
down (Fig. 18J ).

The tensile properties of Snyder's knot were shown to be statistically similar to those of hand-tied square
knots. In addition, Snyder's knot has a higher load to clinical failure than the Overhand knot, the Duncan
loop and the Roeder knot when using Ticron suture; however, a statistically significant difference was not
found (26 ). Another study showed that the biomechanical properties of Snyder's knot were significantly
inferior to the Double-twist knot and the Tennessee Slider (31 ).
