ABSTRACT:
A femoral tunnel entry drill guide for drilling a transverse hole from the side of a patient's knee to intersect a femoral section of a bony ligament tunnel formed in an arthroscopic surgical procedure. The drill guide of the invention has spaced apart parallel reference and external rods, an end of each connecting to ends of a web member forming a U-shaped device, the opposite rod ends bent at equal arcuate angles from the rod longitudinal axis. Each rod bent end has a transverse hole formed laterally therethrough, which holes align, and the external rod bent end transverse hole is threaded to receive a guide sleeve turned therethrough that has a straight bore for receiving a drill turned therethrough. Which reference rod bent end includes a longitudinal slot formed form the rod end to intersect the transverse. The reference rod bent end is fitted through a port formed through the skin of the knee, below the patella, and into the femoral tunnel section end in the intra articular joint. After entry, the drill guide reference rod is pivoted as the reference rod bent end slides into the femoral tunnel section, with a hole drilled through the external rod bent end transverse hole and into the distal femur to intersect the reference rod bent end transverse hole.
