In a first embodiment, the present invention includes an instrument for use in preparing a femur for soft tissue repair or reconstruction, including a cannulated, curved guide tool having a cannulated body extending to a distal tip and a plane defined by a longitudinal axis of the cannulated body and distal tip; and a flange secured to the distal tip and extending from the distal tip in a direction transverse from the distal tip, the flange having a first curve along at least a portion of the flange and a degree of tilt, relative to the plane, along at least a portion of the flange. In an alternate embodiment, the present invention may also include a method of preparing a bone for reattachment of soft tissue thereto, including visualizing a reattachment site; selecting a guide tool from a plurality of cannulated curved guide tools, each of the plurality of guide tools having a distal tip that includes a flange; directing the distal tip of the selected guide tool towards the reattachment site; and placing the flange against the surrounding anatomy such that the distal tip is on the reattachment site.

1. An instrument for use in preparing a femur for soft tissue repair or reconstruction, comprising: a cannulated, curved guide tool having a cannulated body having a length extending between a proximal end and a distal tip defined by a rim of the cannulated body, the length also extending through a curve adjacent to the distal tip such that at least a first longitudinal axis extends through the guide tool adjacent to the distal tip and is transverse to a second longitudinal axis that extends through the guide tool adjacent to the proximal end, and wherein a plane is defined along the length of the cannulated body such that the plane is positioned through the proximal end, a point on the distal tip closest to the proximal end and the curve,wherein the curve of the cannulated body extends toward the proximal end from the rim; anda flange secured to the distal tip, extending from the distal tip and offset from the plane, the flange having a longitudinal shape defined by a first curve extending in at least a first direction along at least a first portion of the flange and a degree of tilt, relative to the plane, along at least a second portion of the flange wherein the second portion overlaps with the first portion,wherein the flange includes a surface on the second portion at an oblique angle relative to the plane and defining the tilt relative to the plane. 2. The instrument of claim 1, further comprising a second curve in at least a second direction, different from the first direction, along at least a portion of the flange. 3. The instrument of claim 2, wherein at least a portion of the flange includes both the first and second curves. 4. The instrument of claim 2, wherein the first and second curves extend along substantially the same portion of the flange. 5. The instrument of claim 2, wherein the first and second curves extend along different portions of the flange. 6. The instrument of claim 2, wherein one end of the second curve is at an angle of between 0 degrees and 30 degrees relative to the plane. 7. The instrument of claim 1, wherein one end of the first curve is at an angle between 0 degrees and 90 degrees relative to the first longitudinal axis of the guide tool adjacent to the distal tip. 8. The instrument of claim 1, wherein the degree of tilt is an angle between but not including 0 degrees and 90 degrees relative to the plane. 9. The instrument of claim 8, wherein the angle of the degree of tilt is an angle of 45 degrees relative to the plane. 10. The instrument of claim 1, wherein the flange has a complex three-dimensional shape that substantially mimics the anatomy of a distal portion of the femur such that the flange is adapted to engage the anatomy along a substantial portion of the flange. 11. The instrument of claim 10, wherein the shape substantially mimics an edge of a condyle on the distal portion of the femur. 12. The instrument of claim 1, wherein the cannulated, curved guide tool is adapted to accept a flexible drill pin through the cannulated body, wherein the flexible guide pin may exit out the distal tip and into bone. 13. The instrument of claim 12, wherein the flange extends in a direction transverse to the flexible drill pin exiting from the distal tip of the cannulated body. 14. A method of preparing a bone for reattachment of soft tissue thereto, comprising: visualizing a reattachment site; selecting a guide tool from a plurality of cannulated curved guide tools, wherein each of the plurality of cannulated curved guide tools is as recited in claim 1; directing the distal tip of the selected guide tool towards the reattachment site; and placing the flange against and around surrounding anatomy such that the flange is adapted to support the distal tip of the guide tool by wrapping around a condyle, an edge of the condyle, or adjacent to the condyle of the bone, allowing anatomy of the bone to rest within a surface of the flange, and the distal tip is on the reattachment site. 15. The method of claim 14, wherein the flange has a complex three-dimensional surface which substantially mimics the surrounding anatomy. 16. The method of claim 14, further comprising a cannulated body, of the cannulated curved guide tool, extending to the distal tip. 17. The method of claim 16, further comprising inserting a flexible drill pin through the cannulated body such that it exits from the distal tip and projects into the reattachment site on the bone.
