Abstract:
1. A method of repairing a knee, comprising: drilling a longitudinal tibial tunnel through a top section of a tibia; drilling a longitudinal femoral tunnel through a bottom section of an adjacent femur such that the tibial tunnel and the femoral tunnel are substantially in alignment; drilling a substantially transverse tunnel through the femur, such that the transverse tunnel intersects the femoral tunnel, and is in communication therewith, the transverse tunnel having first and second open ends; threading a filamentary member which comprises and endless loop through the tibial and femoral tunnels to the transverse tunnel extending a portion of the loop out of the transverse tunnel with a passing pin member, cutting the loop to form a first end and a second end and engaging the second end of the filamentary member with the passing pin member, such that a first end of the filamentary member extends out from one open end of the transverse tunnel and the second end of the filamentary member is maintained in a section of the transverse tunnel by the passing pin member, and a bottom loop of the filamentary member extends out through a bottom opening of the tibial tunnel; folding an anterior cruciate ligament replacement graft having opposed ends to form a graft loop having a top, a bottom, and an opening; engaging the graft with a suture which is attached to a surgical needle such that the suture passes through the graft loop opening; engaging the graft with the filamentary member such that it passes through the graft loop opening; pulling the graft loop up and into the femoral and tibial tunnels by pulling on the needle and suture, whereby the filamentary member is simultaneously moved into the femoral tunnel, such that the top of the graft is in the femoral tunnel, and the graft loop opening is in alignment with the transverse tunnel; moving the passing pin member and the second end of the filamentary member out of the second open end of the transverse tunnel and manipulating the filamentary member such that it is tensioned to form a substantially straight configuration that is substantially in alignment with the transverse tunnel to serve as a guide wire; and securing the upper end of the graft loop in the femoral tunnel by passing a cannulated bone pin over the filamentary member and through the graft loop opening, and mounting the bone pin in the transverse tunnel.
