Assemble the Femoral Sizer with the Femoral Stylus
in the lateral hole (for both a left or right knee) and
set the stylus length to an approximate size .
>
Set the rotation to LEFT for a left knee and RIGHT
for a right knee and adjust to the desired amount of
external rotation .
>
The Femoral Sizer also sets the final rotation of the
femoral component . Additional checks for rotation
may be made by lining up the epicondyles with the
reference lines marked “EPI” or assessing Whiteside’s
line with a pin through the hole in the top of the guide .
Note: In the event of a hypoplastic femoral condyle: Pin
the Femoral Sizer through the EPI hole on the unaffected
side for stability . Rotate the Femoral Sizer and assess
rotation using the rotational checks mentioned above .

Position the assembly flush on the resected distal
femur, sliding the feet of the Femoral Sizer under
the posterior condyles . The Femoral Stylus point
should be placed at the anticipated level of resection,
commonly the lateral cortex .
>
It is important that the Femoral Stylus point rest on
bone and not on soft tissue .
>
The size is determined by the position of the scribe
mark on the Femoral Stylus shaft within the sizing
window .
