1. An orthopedic drill guide device comprising:

  • (a) a handle;

    (b) a tibial component; and

    (c) a threaded nut for securing the tibial component to the handle;

    said handle having an arm with a first and second end, attached to said first end of said arm is a hollow sleeve having a longitudinal axis and a means for slideably receiving and aligning with the tibial component, attached to said second end of said arm is a pilot tube with a longitudinal axis parallel to the longitudinal axis of said hollow sleeve, said pilot tube having at one end at least one bone-engaging tooth;

    said tibial component having an alignment rod with a first and second end, said alignment rod having a threaded section extending over all or part of its length beginning from said first end, said alignment rod having a longitudinal axis and engaging said slideably and receiving aligning means of the hollow sleeve of the handle in a direction parallel to the longitudinal axis of the alignment rod, said tibial component having a locating arm with a first and second end and an inner and outer edge, the first end of said locating arm being attached to the second end of said alignment rod, the second end of said locating arm being tapered to a sharp point, the inner edge of said locating arm intended to contact the posterolateral corner of the intercondylar notch of a femur bone, said inner edge contact in conjunction with the tapered point of the second end of the locating arm and a tooth of the pilot tube of the handle planarly locating said drill guide for the purpose of drilling a through-hole in a bone;

    wherein the threaded section of the tibial component alignment rod is positioned in the hollow sleeve of the handle so that the means for slideably receiving and aligning the alignment rod with the hollow sleeve is engaged, the sharp pointed second end of the tibial component locating arm is positioned to engage one surface of a tibial bone and the bone engaging tooth of the tubular pilot of the handle is positioned to engage a second surface of the tibial bone, the nut being threaded onto the alignment rod threads to compressively secure the handle and tibial component to the bone for the purpose of aligning and drilling a through-hole in said tibial bone.
