Method for anterior cruciate ligament reconstruction using cross-pin implant with eyelet
First Claim
1. A method of surgery comprising the steps of:
- forming an opening having side walls in a bone;
forming a transverse hole through the side walls of the bone;
inserting a graft having a loop into the opening;
inserting a flexible strand through an eye formed in a distal end of an implant;
pulling the implant through the transverse hole formed through one of the side walls and into the opening by pulling on the flexible strand; and
fixating the graft in the opening by drawing the implant through the loop of the graft by pulling on the flexible strand, such that the implant spans the opening and is supported by the side walls of the bone.

Abstract
A surgical implant for securing ligament grafts into a joint. The implant is formed entirely of allograft cortical bone, and has a tapered tip with a suture eye. A length of suture is knotted or looped through the eye. The suture is used to draw the implant transversely through a looped graft construct to fix the graft by spanning a bone socket, for example. In a preferred embodiment, the implant is used for knee ligament repair by forming a longitudinal socket in a bone. A flexible strand is drawn with the pin through the bone. A looped portion of the flexible strand is diverted so as to protrude out of the entrance to the longitudinal socket. The ends of the flexible strand remain accessible on either side of the bone. The ligament graft is captured within the strand loop protruding from the entrance to the socket. The strand is retracted into the socket, drawing the graft into the socket by pulling on the accessible ends of the flexible strand. The graft is fixed in the socket using the transverse implant.

14. A method of anterior cruciate reconstruction surgery of the knee, comprising the steps of:
-
forming an opening in a femur, the opening having an entrance facing a joint of the knee;
forming a transverse hole through a side wall of the femur and into the opening in the femur;
coupling a graft over to a first flexible strand outside of the knee;
lifting the graft through a tunnel in the tibia and into the opening of the femur by pulling on the first flexible strand; and
securing the graft in the opening of the femur by advancing an implant provided with an eye transversely into the opening and under the graft, by pulling on a second flexible stand inserted through the eye of the implant.- View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22)
