Femoral Sizing
(cont.)
Note:
Assessing the A/P femoral axis, the
epicondylar axis, flexion gap and the tibial shaft
axis can further optimize femoral rotation.
Due to the tight space, hyperflex the knee to place
the A/P sizer flush with the resected femoral distal
surface.
Drill the two 4-in-1 cutting block location holes
utilizing the 1/8 inch quick release drill pins (Figure 16A).
Leave the pins in place.
The femoral component size can now be read from
the central scale (Figure 16B).
Vanguard ID Tip:
If the size indicated is in-
between sizes, use the smaller of the two sizes,
in order to not overstuff the patellofemoral joint
space.
Remove the pins and the A/P sizer.
