Claim:
A fixation device for securing a transplant in a bone tunnel, comprising: a strap having a plurality of protrusions disposed along its length; a fastening member having an aperture therein for passing the strap; and a connection element disposed at a distal end of said strap for engaging a transplant; said connection element further comprising a shoulder adapted to engage a notch within the bone tunnel, said shoulder having a width that is greater than a diameter of a first tunnel section in the bone and that is smaller than a diameter of a second tunnel section in a bone disposed distally of said first tunnel section; said fastening member further comprising a distal side, a longitudinal axis of said aperture being substantially parallel to a longitudinal axis of said bone tunnel when said fastening member distal side lies substantially flush against an outer surface of the bone; said fastening member further comprising a self-locking element having a camming surface adjacent to a locking surface positioned to engage at least one of said plurality of protrusions and a stem, said camming surface defining a portion of said aperture and said locking surface being parallel to the distal side of said fastening member, wherein said camming surface is positioned at a 45 degree angle with respect to the distal side of said fastening member, said stem flexibly connecting said self-locking element to said fastening member; wherein upon insertion of said strap within said aperture, said plurality of protrusions cause said stem to flex slightly inward until said plurality of protrusions engage said locking surface.
