1. In combination, a secondary surgical implant and a primary surgical implant, said secondary surgical implant for use with said primary surgical implant in a bone tunnel having an axis, a predetermined diameter along the length of said tunnel, a proximal end and a distal end, said primary surgical implant engaging a ligament graft within said bone tunnel, said ligament graft being in alignment with said axis and occupying a predetermined amount of space within said tunnel such that the transverse cross-sectional area of the graft-occupied portion of said tunnel comprises a first predetermined size at a first point adjacent said primary implant, said first predetermined size being less than that of the graft-unoccupied portion of said tunnel at a second point adjacent the distal end of the tunnel, said second point being distal of said primary surgical implant and longitudinally spaced distally from said first point, said secondary implant comprising:

  • a body having a second predetermined size smaller than said predetermined diameter to enable said body to fit within said bone tunnel distal end but greater than said first predetermined size whereby said body is too large to come out of said bone tunnel past said primary surgical implant; and

    means to enable said body to be secured to said ligament graft.
