A flexible reamer for preparing a hole in a tissue includes a shaft that extends along a longitudinal axis between a proximal end and a distal end. The shaft is cannulated through and has a flexible portion along at least a portion of its length. The flexible portion includes a plurality of discrete, interlocking portions. An asymmetric tip at the distal end of the shaft has at least one flute positioned off-axis relative to a longitudinal axis of the flexible reamer.

1. A method of preparing a hole in a distal portion of a femur, the method comprising the steps of: forming an anterior-medial portal in soft tissue adjacent a knee joint;inserting a distal portion of a curved guide tool through the portal and into the joint;directing a distal tip of the distal port
1. A method of preparing a hole in a distal portion of a femur, the method comprising the steps of: forming an anterior-medial portal in soft tissue adjacent a knee joint;inserting a distal portion of a curved guide tool through the portal and into the joint;directing a distal tip of the distal portion towards the surface of the femur; anddirecting a flexible guide pin to the surface of the femur with the curved guide tool,wherein the curved guide tool is cannulated throughout its length such that a proximal portion of the curved guide tool includes a first cannulated opening and the distal portion of the curved guide tool includes a second cannulated opening,wherein the step of directing the flexible guide pin includes passing a distal portion of the flexible guide pin through the first and second cannulated openings and to the surface of the femur,wherein the curved guide tool includes a plug positioned adjacent to the first cannulated opening, the plug including an elongate portion pivotable about an axis of rotation between an open position, substantially clear of the first cannulated opening, and a closed position, substantially blocking the first cannulated opening, the elongate portion having a length extending between the axis of rotation and a free end, andwherein when the elongate portion pivots about the axis of rotation, a shape of the elongate portion remains the same. 2. The method of claim 1, wherein the plug is biased in the closed position. 3. The method of claim 2, further comprising the steps of: establishing a supply source of a clear fluid into the joint;prior to forming the anterior-medial portal, forcing the clear fluid into the joint from the supply source;upon inserting the curved guide tool through the portal, preventing the clear fluid from exiting the joint through the curved guide tool with the plug; andupon passing the flexible guide pin through the first cannulated opening, moving the plug to the open position with the distal portion of the flexible guide pin. 4. The method of claim 3, further comprising the step of removing the flexible guide pin from the first cannulated opening, wherein the plug returns to the closed position. 5. The method of claim 1, further comprising the step of passing the distal portion of the flexible guide pin through the surface of the femur and exiting out a lateral aspect of the femur. 6. The method of claim 1, wherein the step of directing the flexible guide pin to the surface of the femur occurs after the step of directing the distal tip of the curved guide tool towards the surface of the femur. 7. The method of claim 1, wherein the distal tip of the curved guide tool includes a flange, and wherein the step of directing the distal tip of the curved guide tool includes mating the surface of the femur, soft tissue on the femur, or both, with the flange. 8. The method of claim 7, wherein the flange includes at least a first offset from a longitudinal axis of the curved guide tool, the at least one offset forming a surface of the flange adapted to index with the surface of the femur, surface of the soft tissue on the femur, or both. 9. The method of claim 7, wherein the flange has a complex three-dimensional shape formed by at least a first offset. 10. The method of claim 1, wherein the steps are performed with the knee bent at 90 degrees flexion. 11. A method of preparing a hole in a distal portion of a femur, the method comprising the steps of: forming an anterior-medial portal in soft tissue adjacent a knee joint; inserting a distal portion of a curved guide tool through the portal and into the joint; directing a distal tip of the distal portion towards the surface of the femur; and directing a flexible guide pin to the surface of the femur with the curved guide, wherein the distal tip of the curved guide tool includes a flange, and wherein the step of directing the distal tip of the curved guide tool includes mating a curved portion of the flange with a corresponding portion of an unmodified curved surface of a lateral condyle of the femur, soft tissue on the lateral condyle of the femur, or both, to create a stable connection. 12. A method of preparing a hole in a distal portion of a femur, the method comprising the steps of: establishing a supply source of a clear fluid into the joint;forcing the clear fluid into the joint from the supply source;forming an anterior-medial portal in soft tissue adjacent a knee joint;inserting a distal portion of a curved guide tool through the portal and into the joint and upon inserting the curved guide tool through the portal, preventing the clear fluid from exiting the joint through the curved guide tool with a plug of the curved guide tool, wherein the curved guide tool is cannulated throughout its length such that a proximal portion of the curved guide tool includes a first cannulated opening and the distal portion of the curved guide tool includes a second cannulated opening,wherein the plug is positioned adjacent to the first cannulated opening and is pivotable between an open position, substantially clear of the first cannulated opening, and a closed position, substantially blocking the first cannulated opening, andwherein the plug is biased in the closed position;directing a distal tip of the distal portion of the curved guide tool towards the surface of the femur;directing a flexible guide pin to the surface of the femur with the curved guide tool by moving the plug to the open position with a distal portion of the flexible guide pin and passing the distal portion of the flexible guide pin through the first and second cannulated openings and to the surface of the femur, andremoving the flexible guide pin from the first cannulated opening such that the plug pivots to the closed position. 13. A method of preparing a hole in a distal portion of a femur, the method comprising the steps of: forming an anterior-medial portal in soft tissue adjacent a knee joint;inserting a distal portion of a curved guide tool through the portal and into the joint;directing a distal tip of the distal portion towards the surface of the femur; anddirecting a flexible guide pin to the surface of the femur with the curved guide tool,wherein the curved guide tool is cannulated throughout its length such that a proximal portion of the curved guide tool includes a first cannulated opening and the distal portion of the curved guide tool includes a second cannulated opening,wherein the step of directing the flexible guide pin includes passing a distal portion of the flexible guide pin through the first and second cannulated openings and to the surface of the femur,wherein the curved guide tool includes a plug positioned adjacent to the first cannulated opening, the plug including a first elongate portion and a second elongate portion, the first and second elongate portions being colinear over their respective lengths and extending in opposite directions from an axis of rotation,wherein the plug is pivotable about the axis of rotation between an open position, substantially clear of the first cannulated opening, and a closed position, substantially blocking the first cannulated opening, andwherein when the elongate portion pivots about the axis of rotation, the first elongate portion and the second elongate portion remain colinear.
