A femoral guide for precisely positioning a guide wire on a femur bone surface. A lumen allows a guide wire extending through the lumen to contact the bone surface at a location spaced a predetermined distance from an edge of the bone surface. With the guide wire driven into the bone, a bone tunnel can be formed substantially concentrically along the guide. Methods of precisely forming bone tunnels include the steps of engaging a bone surface edge with a tongue of the femoral guide, insertion of a guide wile through a femoral guide lumen, driving the guide wire into the bone through the lumen and forming a bone tunnel along the guide wire where a bone tunnel longitudinal axis is disposed from the edge engaged by die tongue a distance substantially equal to the distance that the tongue is disposed from the longitudinal axis of the lumen.

Femoral guide and methods of precisely forming bone tunnels in cruciate ligament reconstruction of the knee

A femoral guide for precisely positioning a guide wire on a bone surface of the femur includes a body having a lumen for receiving a guide wire and a tongue protruding from the body for engaging an edge or reference point on the bone surface with the tongue being spaced a predetermined distance from a longitudinal axis of the lumen. The lumen includes an opening allowing a guide wire extending through the lumen to contact the bone surface at a location spaced from the edge substantially the predetermined distance with the tongue engaging the edge. A stylus on the body can be driven into the bone to secure and stabilize the femoral guide prior to driving the guide wire into the bone through the lumen. With the guide wire driven into the bone, a bone tunnel can be formed substantially concentrically or coaxially along the guide wire such that a longitudinal axis of the bone tunnel will be disposed from the edge substantially the predetermined distance. Methods of precisely forming bone tunnels include the steps of engaging an edge of a bone surface with a tongue of the femoral guide, inserting a guide wire through a lumen of the femoral guide, driving the guide wire into the bone through the lumen and forming a bone tunnel in the bone along the guide wire such that a longitudinal axis of the bone tunnel will be disposed from the edge engaged by the tongue a distance substantially equal to the distance that the tongue is disposed from a longitudinal axis of the lumen.
