Abstract
A method of reconstructing a ruptured anterior cruciate ligament in a human knee. Femoral and tibial tunnels are drilled into the femur and tibia. A transverse tunnel is drilled into the femur to intersect the femoral tunnel. A filamentary loop is threaded through the femoral tunnel and tibial tunnel and partially through the transverse tunnel. A replacement graft is formed into a loop and moved into the tibial tunnels using a surgical needle and suture. A flexible filamentary member is simultaneously moved along with the loop into the femoral and transverse tunnels. The filamentary member is used as a guide wire in the transverse tunnel to insert a cannulated cross-pin to secure a top of the looped graft in the femoral tunnel.
