Resect Distal Femur
TECHNIQUE TIP 2.C
- It is recommended to use new saw blades for femoral resections.
- Areas where the bone transitions from high to low density, such as
from cortical to cancellous bone, may cause the saw blade to skive
and result in an inconsistent cut. Use caution when resecting in these
regions and operate the saw at high speed but advance the saw
slowly to ensure a consistent cut.
- The flatness of the distal femoral resection is critical to ensuring
sufficient contact between the Persona Trabecular Metal femoral
implant and the bone. Evaluate the flatness of the distal femur
resection with a flat surface, such as the distal resection cutting
guide, especially around the intercondylar notch, prior to sizing.
Modify the distal femoral surface, if necessary, to ensure
subsequent guides and the implant fit properly.

• After completing the cut, remove pins and the cutting head.
• Squeeze the button on the resection guide (Fig. 11) to
release and remove the alignment guide and resection guide
assembly from the cutting head. The modular T-handle is used
to remove the IM Rod, prior to the distal femoral resection.
• Alternatively, the T-handle can be used to remove the IM
Rod while the button on the resection guide is squeezed to
facilitate rapid removal of the IM rod, the alignment guide and
the resection guide at the same time. If necessary, the round
end of the Slaphammer Extractor can be used in conjunction
with the central hole in the T-Handle to remove the IM rod.
• Cut the distal femur through the cutting slot in the cutting
head, using a 1.27mm (0.050 in.) oscillating saw blade
(Fig. 12) . If the optional uncaptured technique is used,
the distal femur should be cut on the outside surface
of the capture.
Note: The flatness of the distal femoral resection is
critical to ensuring adequate contact between the
Persona
Trabecular Metal femoral implant and the bone. Evaluate
the flatness of the distal femur resection prior to sizing.
