VANGUARD X P
Total Knee System
• The marks on the gauge indicate a slope difference of
1 degree increments.
• The goal is to be within 1 degree of coplanar
- If the medial and lateral sections are not coplanar
(Figure 37) by more than 1 degree:
º Use the flat rasp to shave off more bone.
º Use the oscillating saw blade to remove excess bone
until cut surfaces are coplanar within 1 degree
(Figure 38).
Tibial Preparation
Tibial Resection with Intact/
Functional ACL (cont.)
Slope Check
• Use the tibial slope gauge (32-700041) to ensure the tibial
slope on both the medial and lateral plateaus is coplanar
for adequate fixation and function of the system
(Figure 36).
• Apply pressure on the posterior region of the
instrument paddles to ensure they are lying flat on
the tibial surface.
