Surgeon Notes and Tips
• Although a sequence of femoral cuts has been
provided, the cuts may be made in any sequence.
It is recommended for the surgeon to complete the
cuts in a consistent sequence to help ensure that all
cuts are performed. However, the peg holes should
be drilled prior to assembling the MIS trochlear
guide.
• If the MIS femoral finishing guide is used, the flexion
gap should equal the extension gap.
• If the MIS flex femoral finishing guide is used, then
the flexion gap will be approximately 2 mm greater.
For an LPS-Flex implant, use an MIS spacer block
with the MIS LPS-Flex spacer block adapter to check
flexion gap.
• An oscillating saw with a narrow blade may also be
used, or a reciprocating blade may be used to cut
the sides and a chisel or osteotome used to cut the
base of the notch.
• When establishing the mediolateral position of
the femoral component, it is recommended to
lateralize the component to help improve patellar
tracking. Avoid positioning the component where
it overhangs the bone as this may restrict flexion.
