VANGUARD X P
Total Knee System
Note: To confirm the valgus angle, the alignment handle
can be inserted into the adjustable distal adaptor and a 1/4"
alignment rod can be inserted and extended to the center of
the femoral head.
• Remove the valgus wing by removing the IM rod and
pulling the valgus wing and valgus block adaptor
distally away from the distal cut block, leaving the distal
cut block in place.
• Use a 1.37 mm saw blade to complete the distal
resection through the selected 0 slot (Figure 13).
eXPert Advice:
• When resecting the distal femur, flex the knee beyond 90
degrees to avoid cutting the ACL when the saw blade exits
the posterior bone.
• It is strongly recommended to resect only 2-3 mm of
cartilage/bone from the femoral notch to respect the
natural joint line when the ACL is intact.
• Check the resected distal femur using a flat instrument
surface to confirm a flat resection.
• Recut or file as necessary to achieve proper resection.

Option 2: Fixed Distal Femoral
Resection Guide
• Choose the appropriate left or right valgus wing (from
32-485004 to 32-485007) and assemble it onto the
IM rod by sliding it through the central hole.
• Slowly introduce the IM rod to the femoral canal to
depressurize the canal.
• Slide the valgus wing until it rests flush with the
distal femur:
- The “left” or “right” engraving on the block must face
distally corresponding to the leg being prepared.
• Slide the distal cut block and valgus block adaptor
(from 32-485014 to 32-485017) into the anterior holes
of the valgus wing until the resection block contacts
the anterior femur.
• Pin the distal cut block into place using 1/8" quick
release drill pins in the center pin holes of the block
(Figure 12).
