Option One: MIS Notch/Chamfer Trochlear Guide
(cont.)
Use a reciprocating saw to cut the sides and base of
the intercondylar box (Figure 7d). Protect the tibia with
a wide osteotome.
Use the patellar/femoral drill to drill the femoral post
holes.
Note: Do not use the LPS-Flex femur peg drill, size
A, B with the MIS notch/chamfer guide as there is
no stop on the guide for this smaller drill. If using
a micro size (A, B) LPS-Flex femoral component,
the femoral post holes must be drilled when the
anterior and posterior condyle cuts are made using
the appropriate size MIS flex femoral finishing guide
and the LPS-Flex femur peg drill.
Then use an oscillating saw to cut the anterior chamfer
and the posterior chamfer (Figure 7e).
Apply the matching size MIS trochlear guide to the MIS
notch/chamfer guide with the holes in the trochlear
guide aligned with the threaded holes in the notch/
chamfer guide (Figure 7f). Thread the MIS threaded
handle through one of the threaded holes to secure
the trochlear guide to the MIS notch/chamfer guide
(Figure 7g).
