Exposure
>
A standard anterior midline incision is utilized.
Any previous incision can be used or incorporated to
decrease the risk of skin slough.
>
The capsule is entered through a medial parapatellar
approach approximately 1cm from the medial border
of the patella.
>
Use a soft tissue approach that allows adequate
patella visualization and sufficient knee flexion.

Femoral Preparation
Femoral Intramedullary Alignment
>
The Universal Driver allows for attachment of all
drills and pins. The Universal Driver may be
attached directly to a reamer, drill, or a Jacob’s
Chuck.
>
Locate the IM drill hole. It is approximately 1cm
anterior to the femoral attachment of the posterior
cruciate ligament and slightly medial to the midline
of the distal femur.
>
Identification of landmarks may be aided by removal
of osteophytes from the margins of the intercondylar
notch.
>
Attach the 3/8
"
IM Drill to the Universal Driver and
drill into the IM canal. The first diameter will create
a tight fit around the IM Rod. If further clearance is
desired, continue to drill until the larger step
diameter opens the hole. This will allow the IM canal
to dictate the position of the rod and avoids the need
to “toggle” the drill to create clearance.
>
Attach the T-Handle Driver to the 5/16
"
IM Rod.
Insert the IM Rod into the Femoral Alignment
Guide. The Femoral Alignment Guide is designed for
use on either the left or right knee and may be set to
5, 6 or 7º of valgus. Set the instrument to the desired
angle by pulling back on the black knob of the
Femoral Alignment Guide and placing it in the
appropriate notch. Advance the rod, with attached
guide, slowly up the IM canal until the desired depth
is reached.
