In one embodiment, the present invention is a method of positioning and securing a graft to bone including the steps of: positioning the graft into a bore hole in the bone; positioning a guide wire into the bore hole in the bone; positioning a slide instrument between the guide wire and the graft; positioning a driver, and an anchor secured thereto, over the guide wire; directing the anchor along the guide wire and towards and into the bore hole; and imparting a rotational force to the anchor to secure the anchor between a sidewall of the bore hole and a portion of the graft.

1. A method for positioning and securing a graft in a prepared bone hole, the method comprising: advancing at least a first portion of the graft into the bone hole;passing a flexible guide wire into the bone hole;positioning a slide instrument between the graft and flexible guide wire such that the slide instrument separates the bone hole into a first side and a second side, such that the graft is positioned within the first side of the bone hole and the flexible guide wire is positioned within the second side of the bone hole;positioning a cannulated driver, having a flexible portion, and a cannulated anchor, engaged with a distal end of the cannulated driver, over the guide wire such that the guide wire is positioned within the cannulated anchor and at least a portion of the cannulated driver;directing the cannulated anchor along the guide wire and into the second side of the bone hole; andfixedly securing the graft in the bone hole by positioning the anchor between a portion of a bone wall of the bone hole and at least part of the first portion of the graft, wherein the part of the first portion of the graft is compressed between another portion of the bone wall of the bone hole and the anchor. 2. The method of claim 1, wherein the slide minimizes contact between the anchor and an at least second portion of the graft. 3. The method of claim 1, wherein the bone hole is a bone tunnel formed in a distal portion of a femur. 4. The method of claim 3, wherein the graft is a replacement anterior cruciate ligament (ACL) graft. 5. The method of claim 1, wherein the anchor is a threaded interference screw, wherein the directing and fixedly securing steps include rotating the threaded interference screw such that the threads of the threaded interference screw engage both the part of the first portion of the graft and the portion of the bone wall of the bone hole. 6. The method of claim 1, wherein a notch is formed along at least part of the portion of the bone wall of the bone hole either prior to the step of advancing the graft or after the step of positioning the slide, wherein the notch maintains the position of the anchor against the portion of the bone wall of the bone hole. 7. A method of positioning and securing a graft to bone comprising: positioning the graft into a bore hole in the bone;positioning a guide wire into the bore hole in the bone;positioning a slide instrument between the guide wire and the graft;positioning a driver, and an anchor secured thereto, over the guide wire;directing the anchor along the guide wire and towards and into the bore hole; andimparting a rotational force to the anchor to secure the anchor between a sidewall of the bore hole and a portion of the graft. 8. The method of claim 7, wherein the slide includes a first channel and a second channel, wherein the guide wire is positioned within the first channel and the graft is positioned within the second channel such that the guide wire and graft remain separated from one another. 9. The method of claim 8, wherein, as the anchor is directed towards and into the bore hole, the anchor and graft remain separated from one another. 10. The method of claim 9, wherein as the anchor is directed further into the bore hole, the anchor is directed past the slide to contact the portion of the graft. 11. The method of claim 8, wherein the first channel includes a concave surface and the second channel includes a concave surface positioned in a direction opposite the first channel. 12. The method of claim 8, wherein the first channel includes a concave surface and the second channel includes a convex surface, wherein the convex surface is bounded between first and second channel edges. 13. The method of claim 7, wherein prior to directing the anchor towards and into the bore hole, forming a notch along at least a portion of the length of the bore hole, such that the anchor is directed along the notch within the bore hole. 14. The method of claim 7, wherein the guide wire includes a curve along at least a portion of its length between a point where the guide wire enters the bore hole and an end of the guide wire, positioned outside the bone. 15. The method of claim 14, wherein the driver includes a portion of a shaft that is flexible such that the driver can be directed over the curve in the guide wire. 16. The method of claim 7, wherein the anchor is an interference screw including a threading along at least a portion of its outer surface, wherein upon imparting the rotational force, the threading engages the sidewall of the bore hole and the portion of the graft. 17. The method of claim 16, wherein the graft comprises a bone-tendon-bone graft, and the portion of the graft engaged by the threading of the interference screw is bone. 18. The method of claim 7, wherein the bore hole is a bone tunnel and the bone is a femur, wherein the graft is a replacement anterior cruciate ligament graft. 19. A method of positioning and securing a graft to bone comprising: positioning a flexible guide wire into a bore hole in the bone, the flexible guide wire having a length;positioning the graft into the bore hole in the bone;positioning a driver, and an anchor secured thereto, over the flexible guide wire, the driver including a shaft, at least a portion of which is flexible;directing the anchor along the flexible guide wire and into the bore hole; andimparting a rotational force to the anchor to secure the anchor between a sidewall of the bore hole and a portion of the graft. 20. The method of claim 19, further including the step of positioning a slide between the flexible guide wire and the graft prior to the step of positioning the driver and anchor over the guide wire. 21. The method of claim 20, wherein the slide includes a first channel and a second channel, wherein the guide wire is positioned within the first channel and the graft is positioned within the second channel such that the guide wire and graft remain separated from one another.
