Abstract
Techniques and reconstruction systems for ligament repair and fixation. A bone tendon graft is prepared by folding the bone block over a suspensory fixation device (for example, a knotless suture construct such as a knotless, adjustable, self-cinching suture loop/button construct, a suture, crosspin, or screw, etc.). A flexible strand is then used to suture the bone plug to the tendon so that the overall graft is shortened significantly and the suspensory fixation device is securely attached. The technique does not require passage of the suspensory fixation device through the bone block which makes the graft passage easier since the graft is pulled from the tip. The technique also allows shortening of the overall graft.
Claims23
A pre-assembled tensionable construct comprising:
- a button,
- a suture construct with a knotless, adjustable closed suture loop connected to the button, and
- a bone tendon construct attached to the suture loop without passage of the suture loop through any portion of the bone tendon construct,
- wherein the bone tendon construct includes
- a bone block integral with a tendon, wherein the bone block is rotated over a portion of the suture loop and onto the tendon to establish a crease within a folded portion of the bone tendon construct, the folded portion of the bone tendon construct is located at an interface between the bone block and the tendon, and the portion of the suture loop is positioned within the crease within the folded portion of the bone tendon construct;
- and
- a plurality of sutures through the bone block and through the tendon to secure the bone block to the tendon.
A reconstruction system for tissue repairs, comprising:
- a button;
- a loop connected to the button;
- a bone tendon graft including a bone block integral with a tendinous portion, the bone tendon graft attached to the loop without passing the loop through either of the bone block or the tendinous portion, the bone block rotated over a portion of the loop onto the tendinous portion to establish a crease within a folded portion of the bone tendon graft, the folded portion located at an interface between the bone block and the tendinous portion,
- and wherein the portion of the loop is positioned within the crease;
- and
- a flexible strand separate from the loop and extending through the bone block and the tendinous portion to secure the bone block to the tendinous portion.
A reconstruction system for tissue repairs, comprising:
- a button;
- a loop connected to the button;
- a bone tendon graft attached to the loop and including a bone block integral with a tendinous portion attached to the bone block,
- wherein the bone tendon graft is attached to the loop without passing the loop through either of the bone block or the tendinous portion of the bone tendon graft,
- wherein the bone tendon graft includes a folded portion located at an apex of the bone tendon graft,
- wherein a portion of the loop is positioned within a crease located immediately inward from the apex and at an interface between the bone block and the tendinous portion;
- and
- a suture pattern extending through both the bone block and the tendinous portion for securing the bone block to the tendinous portion,
- wherein the suture pattern is separate from any portion of the loop,
- wherein each stitch of the suture pattern is located further from the apex than the portion of the loop that is positioned within the crease.
