Introduction
General Considerations
•Zimmer®Patient Specific Instruments (PSI) are 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 cutting guides, avoid the use of spring
pins as these may cause stress / unwanted shift on the
cutting guide.

SECTION
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 anterior medial and lateral 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).
TECHNIQUE TIP 1.A
When drilling the distal pin holes, ensure the holes are deep enough
for visibility after the distal cut occurs.

TECHNIQUE TIP 1.B
When performing the cuts, excessive force (considering the pressure
being applied to the guide) on the medial or lateral side of the cut
guide could influence the amount of varus/valgus in the cut.
TECHNIQUE TIP 1.C
If more fixation is required, insert a 3.2mm trocar tipped pin in the
oblique hole on the cutting head.

Place Distal Cut Guide and Cut Femur
•Remove the Pin Guide by sliding it off the pins, leaving the
anterior pins in the bone.
•Secure the Persona®0° Captured / Uncaptured Cutting Head
(42-5099-010-00).
•Verify the distal resection on the medial and lateral side with
a resection guide. Check alignment if desired, and make the
cut (Fig. 4).
Place the Persona 4-in-1 Femoral Cut Guide
•Secure the Persona 4-in-1 Cut Guide (42-5099-085-54_74
for Anterior Referencing or 42-5099-044-54_74 for Posterior
Referencing) and insert 3.2mm Trocar-tipped pins
through
the oblique holes of the cut guide. Verify resections
using a
resection guide.
•Finish the femur following the instructions from the Zimmer
Persona The Personalized Knee Surgical Technique (Fig. 6).
Remove Distal Cut Guide
•Locate the drilled pin holes.
•Remove the anterior pins (Fig. 5).

TECHNIQUE TIP 1.D
In the event the drilled distal holes are covered up following the distal
cut, clean the area. Alternatively, prior to removing the anterior pins,
place the Pin Guide back over the anterior pins and locate the distal
pins through the distal Pin Guide holes.

SECTION
Tibial Technique
Position Tibial Pin Guide
•Remove the meniscus.
•Do not remove osteophytes from the tibia. Clean the
bone around the ACL and anterior tibia where the guide fits.
Remove any soft tissues that may prevent proper placement
of the Pin Guide.
•Position the Pin Guide on the tibia (Fig. 7).
•The mechanical axis and proximal resection lines may be
used to assess the alignment.
Note: The tibia alignment may be verified by inserting the
Tibia Alignment Adapter and Alignment Rod into the Tibia Pin
Guide alignment holes (Fig. 8a & 8b).
Drill and Pin Anterior Lateral Pin Hole
•Drill and pin the lateral hole of the Pin Guide (Fig. 9).
Drill Anterior Medial Hole
•Drill the medial hole of Pin Guide (do not place pin)
(Fig. 10).

Remove Tibial Pin Guide
•Remove the Pin Guide by lifting the medial hook off the
posterior ridge and sliding off the anterior lateral pin
(Fig. 11). Do not pry the Pin Guide from the tibia as this
could shift the pins. (It may be necessary to remove the
previously placed pin from the anterior lateral hole.)
Place Pins in Anterior Holes
•Ensure both pins are placed in the drilled anterior holes
(Fig. 12).

Secure Cut Guide and Cut Tibia
•Secure the Persona Tibial Cut Guide. If more fixation is
required, insert a 3.2mm Trocar-tipped pin in the oblique
hole on the cutting head. Verify resections using the
resection guide. Make tibial cut (Fig. 13).
•Use the appropriate right or left tibia cut guide.

TECHNIQUE TIP 2.B
When performing the cuts, excessive force (considering the pressure
from leaning on the guide) on the medial or lateral side of the cut
guide could influence the amount of varus/valgus in the cut.
Fig. 13
TECHNIQUE TIP 2.A
When fixating the Cut Guide, excessive force from screws can alter the
planned location and could influence the amount of varus/valgus in
the cut.
