Femoral Sizing
• Assemble the selected right or left A/P sizer feet to the
A/P sizer body (32-485050).
• Feet options are:
- Adjustable A/P sizer dial feet, left (32-700374) and
right (32-700373) with the ability to set external
rotation from 0 to 10 degrees (Figure 14).
- Fixed 3 degree A/P sizer feet, left (32-700372) and
right (32-700371) (Figure 15).
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" quick release drill pins (32-467619) (Figure 16A).
• Leave the pins in place.
• The femoral component size can now be read from the
central scale (Figure 16B).
eXPert Advice: If the size indicated is in-between sizes,
use the smaller of the two sizes, in order to not overstuff
the patellar femoral joint space.
• Remove the pins and the A/P sizer.
