1.
Flex the knee to 90° and insert the appropriate sized
femoral trial using the femoral trial impactor.
Note: To avoid the trial slipping into flexion, the trial
femoral impactor can also be used as a notch Impactor
by rotating it 180 degrees and impacting the anterior
femoral notch area (Figure 19).
2.
The femoral trial should be both fully seated and flush
with the lateral cortex avoiding excessive overhang
on either side of the bone. If overhang is present a
narrow implant can be selected, indicated by the laser
markings either side of the trial.
Note: It is important also to assess the fit of the trial
in the trochlea and trochlea junction area to avoid any
overhang.
3.
Secure the femoral trial to the bone using two short
headed pins in the anterior flange (Figure 20).
4.
The ANTHEM™ femoral trials are available in either metal
or high grade polymer. If using Metal Trials, insert the
appropriate sized housing collet (size 1-2 or 3-8) to the
trial femoral component by sliding the housing collet
from anterior to posterior in the provided slot.
4a
.If polymer femoral trials are used then attach the
collet guide housing first on to the distal surface of the
femoral trial by screwing in the distal screws into the
femoral lug holes. Then slide the appropriate sized
collet guide into the housing from anterior to posterior
(Figure 21).
