and Chamfer Resections
By hand, place the 4-in-1 cut guide on the femur by
aligning the two pins on the back of the guide with
the previously drilled positioning holes (Figure 42).
Impact the face of the guide until the guide is flush
with the femur. Place the resection guide through
the anterior slot of the cut guide to ensure the
desired anterior resection (Figure 43). If inadequate
bone will be removed from the anterior cortex, drill
through the two holes on the face of the cut guide
(Figure 44a). Use the slaphammer to axially
remove the cut guide (Figures 45a and 45b). Place
the next smaller-sized femoral cut guide on the
femur in the newly drilled “posteriorized” drill
holes (Figures 44a and 44b). Verify the anterior
and posterior resection levels with the resection
guide to assure that the desired resections will
be attained. If too much posterior bone will
be resected the original femoral cut guide can
be used.
Technique Tip:
If the 2 mm shift holes are to be
used, assure that the desired holes on the distal
femur are used. The resection guide can be used
as final verification of the anticipated anterior and
posterior resections.
Technique Tip:
If there is a risk of anterior
notching, the 4-in-1 cut guide can be removed,
rotated 180 degrees and be replaced on the distal
femur. Holes can then be drilled through the
2 mm shift holes on the face of the 4-in-1 guide.
The 4-in-1 guide then needs to be removed, rotated
180 degrees and be placed on the distal femur in
the anteriorized holes. This will result in a 2 mm
anterior shift of the 4-in-1 femoral resections. Using
the resection guide, verify that the desired anterior
and posterior resections will be attained.
Optional Instrument
The shift block can be used to internally or externally
rotate the 4-in-1 cut guide 2 degrees and/or shift 1
mm in the anterior or posterior direction. Refer to
Appendix C: Optional Instruments: Shift Block, for use.
