Exposure
>
Triathlon Total Knee Arthroplasty can be performed
through any standard approach . A standard anterior
mid-line incision or other suitable approaches such
as mid-vastus, sub-vastus or quadriceps sparing may
be used based on surgeon preference .
>
Any previous incision can be used or incorporated to
decrease the risk of skin slough .
>
The capsule is entered through a medial parapatellar
approach .

Femoral Intramedullary (IM) Alignment
>
The Universal Driver allows for attachment of all
drills and pins . It 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 mid-line
of the distal femur .
>
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 .
>
Attach the T-Handle Driver to the 5/16˝ IM Rod .
>
Insert the IM Rod into the Femoral Alignment Guide
as far proximal as possible . The Femoral Alignment
Guide is designed for use on either the left or right
knee and may be set to 5°, 6° or 7° 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 .
