Adjustable graft fixation device
Systems and methods for securing a soft tissue graft to bone are provided herein. In one embodiment, a surgical implant can include an elongate body having a longitudinal axis extending therealong and having first and second through-holes that are offset to a first side of the longitudinal axis and a third through-hole that is offset to a second side of the longitudinal axis and that is positioned between the first and second through-holes. The implant can also include a suture length extending through the first, second, and third through-holes such that a self-locking knot is formed on a first side of the body and a plurality of suture loops are formed on a second side of the body opposite the first side.
1. A method for preparing a surgical implant, comprising:
threading first and second terminal ends of a suture length through a first through-hole formed in a body such that a securing loop formed from a mid-portion of the suture length extends above the first through-hole on a first side of the body;
threading the first and second terminal ends of the suture length through a second through-hole formed in the body to create first and second fixation loops extending below a second side of the body opposite the first side;
threading the first and second terminal ends of the suture length through the first through-hole such that they extend below the second side of the body;
threading the first and second terminal ends of the suture length through a third through-hole formed in the body to create third and fourth fixation loops extending below the second side of the body, wherein the third through-hole is positioned between the first through-hole and the second through-hole and an axis of a center of the third through-hole is offset from an axis extending through centers of the first and second through-holes; and
threading the first and second terminal ends of the suture length through the securing loop formed on the first side of the body.
2. The method of claim 1 , further comprising applying tension to the first and second terminal ends of the suture length to collapse the securing loop and form a self-locking knot positioned over the first through-hole.
3. The method of claim 2 , further comprising forming at least one half hitch using the first and second terminal ends of the suture length to further secure the self-locking knot.
4. The method of claim 1 , further comprising extending a soft tissue graft through at least one of the fixation loops extending from the second side of the body.
5. The method of claim 4 , wherein the soft tissue graft is extended through the first and second fixation loops, and wherein the method further includes extending a second soft tissue graft through the third and fourth fixation loops.
6. The method of claim 1 , further comprising extending a soft tissue graft through each of the fixation loops extending from the second side of the body.
7. The method of claim 6 , further comprising twisting the third and fourth fixation loops 180° prior to extending the soft tissue graft therethrough.
