Ligament reconstruction graft anchor apparatus

DETAILED DESCRIPTION I claim: 1.
A ligament reconstruction graft anchor assembly for securing a graft ligament to a bone having a tunnel formed therein, comprising: a body member having a first end, a second end, a central opening and an external screw thread; graft fixation means secured to said first end of said body member, said graft fixation means being rotatable relative to said body member; and said body member having means for receiving a driver, said means for receiving extending through said body member from said first end to said second end.
2.
An anchor assembly for securing a replacement ligament graft in an opening in a bone structure, said anchor assembly comprising: a sleeve member having a first end and a second end, an axial extending passageway therein and an external screw thread; an insert member positioned in said passageway and secured to said sleeve member, said insert member having means for receiving a driver at both of its ends; and a ring member rotatably affixed to said insert member, said ring member having graft fastening means thereon.
3.
The anchor assembly of claim 2 further comprising annular groove means formed in said anchor assembly between said sleeve member and said insert member, and wherein said ring member is rotatably affixed in said groove means.
4.
A graft anchor assembly for securing a graft to a bone having a tunnel formed therein, comprising: a body member having a first end, a second end, and an external screw thread; graft fixation means secured to said first end of said body member, said graft fixation means being rotatable relative to said body member and including fastening means for enabling the graft to be fixedly attached to said graft fixation means; said graft fixation means comprising continuously cylindrical ring means integrally and rotatably coupled to said body member; means for engaging a driver to enable rotatable placement of said body member in the bone tunnel while said graft fixation means is rotatably secured to said body member and the graft is fixedly attached to said graft fixation means to minimize torquing the graft; and said first end of said body member comprising flange means and said graft fixation means including holding means positioned over said flange means, said holding means including a rim of said ring means which extends radially inwardly to slidably engage said body member
