Position Femoral Pin Guide
• Do not remove osteophytes from the femur.
• Position the Pin Guide on the distal femur (Fig. 17) .
• Pin Guide will be captured by the anterior and proximal
ridge of the femur. The guide fits over the edge on the
proximal bone to increase locking.
• The A/P axis reference line on the Pin Guide can be used
to assess alignment. The most distal end of the guide is
parallel to the epicondylar axis and can also be used as
reference.
• Apply anterior proximal pressure to the Pin Guide and verify
a secure fit. Applying posterior pressure may destabilize the
Pin Guide.
Drill and Pin the Anterior Pin Holes
• Drill and pin the medial and lateral pin holes of the Pin
Guide using the Universal Disposable Drill (2001-00-00)
(Fig. 18) .
Drill Distal Pin Holes
