Surgical Technique
Step Three: Cut the Distal Femur
While the adjustable IM alignment guide is being
inserted by the surgeon, the scrub nurse should attach
the mini distal femoral cutting guide to the 0° distal
placement guide (Figure 3a). A 3° distal placement
guide is available which will resect the femur in 3° of
flexion.
Ensure that the attachment screw is tight.
Insert the distal placement guide with the cutting
guide into the adjustable IM alignment guide until
the cutting guide rests on the anterior femoral cortex
(Figure 3b). The mini distal femoral cutting guide is
designed to help avoid soft tissue impingement.
Using the 3.2 mm drill bit, drill holes through the two
standard pin holes marked “0” in the anterior surface
of the mini distal femoral cutting guide, and place
headless holding pins through the holes (Figure 3c).
Additional 2 mm adjustments may be made by using
the sets of holes marked -4, -2, +2, and +4. The
markings on the cutting guide indicate, in millimeters,
the amount of bone resection each will yield relative to
the standard distal resection set by the adjustable IM
alignment guide and standard cut plate.
