formed in the proximal end of each anchor half 90 92 respectively then as shown in fig4 the anchor 96 is slid upwardly along the tendon bundles 20 until the anchor 96 bottoms out against the angular surface in the tibial hole 16 as with the first embodiment again as in the first embodiment this positioning will cause the distal end 98 of the anchor 96 to be located in close proximity to the distal end 86 of the tibial tunnel 16 so that good aperture fixation will result then as illustrated in fig5 the tendons are appropriately tensioned and the screw 28 is inserted and tightened together with the retainer cup 94 until seated this action of inserting and tightening the screw 28 and screw retainer cup 94 will cause the anchor portions 90 92 to move laterally outwardly in order to engage the tendon bundles 20 between the anchor portions 90 92 and adjacent tibial bone as in the sheath anchor embodiment fig5 and 52 illustrate the anchor 96 in its fully installed condition after the tendon ends 88 are trimmed flush and the procedure is otherwise completed fig5 57 illustrate in somewhat greater detail and in an assembled configuration a cone anchor 96 of a type very similar to that illustrated in the embodiment of fig4 52 like elements are denoted by like reference numbers a modified tibial anchor embodiment 100 is illustrated in fig5 60 this embodiment is similar to prior disclosed embodiments to the extent that there.
