Introduction
General Considerations
• Zimmer® PSI is not designed for use with the Zimmer
MIS Quad-Sparing™ Total Knee Procedure.
• Zimmer PSI should be used in conjunction with a femur
first technique.
• Verify stability and fixation of all pins. When securing the
conventional tibia cutting guides, avoid the use of spring
pins as these may cause stress / unwanted shift on the
tibia cutting guide.

Femoral Technique
Position Femoral Pin Guide
• Do not remove osteophytes from the femur.
• Position the Pin Guide on the distal femur (Fig. 1).
• Pin Guide will be captured by the anterior and proximal
ridge of the femur. The guide fits over the edge on the
proximal bone to increase locking.
• The A/P axis reference line on the Pin Guide can be used
to assess alignment. The most distal end of the guide
is parallel to the epicondylar axis and can also be used
as reference.
• Apply anterior proximal pressure to the Pin Guide
and verify a secure fit. Applying posterior pressure
may destabilize the Pin Guide.
Drill and Pin the Anterior Pin Holes
• Drill and pin the medial and lateral anterior pin holes of
the Pin Guide using the Universal Disposable Drill
(2001-00-000) (Fig. 2).
Drill Distal Pin Holes
• Drill the distal pin holes of the Pin Guide (do not place pins)
(Fig. 3).
