anteromedial portal referring next to fig5 graft 2 is pulled distally to visualize the whip stitching 6 8 and to position the femoral retroscrew 50 between the two strands of the folded graft 2 the graft 2 is pulled slowly so that it is seated fully in the femoral socket 40 while advancing the screw 50 into the femoral socket 40 between the graft strands a probe not shown may be used to orient the two bundles of graft 2 anatomically into the respective notches of femoral tunnel 40 the distal end of the whip stitching 6 8 should be flush with the opening of tunnel 40 prior to insertion of screw 50 the graft 2 is tensioned in the femoral socket 40 and graft strands are positioned into the notches of the femoral tunnel 40 the femoral retroscrew 50 is positioned between the graft strands and axially aligned with the tunnel 40 in 90 u00b0 of knee flexion the diameter of femoral retroscrew 50 should be equal to or 1 mm larger than the diameter of the drilled femoral socket the femoral retroscrew 50 separates the folded graft 2 into two anatomical bundles the concentrically positioned screw 50 under the looped graft 2 substantially increases femoral pull out strength of the graft 2 as compared to prior techniques referring to fig7 the knee is cycled and the driver 48 is reloaded with a 2 fiberstick u2122 56 and reinserted up the tibial tunnel 36 anterior to the graft 2 the.
