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

Abstract

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.
