Warranty and Service
The Plié 3 MPC Knee has a 36 month warranty and includes
two service intervals, 12 and 24 months after purchase. Service
is required to maintain warranty validity. Your prosthetist will
contact you to schedule an appointment when it is time to
receive knee service. You will be provided with a loaner knee
unit while your knee receives service.
Care & Use
The Plié 3 MPC Knee is safe for occasional submersion in fresh
water up to 1m (3 ft) for up to 30 minutes. You should dry the
knee with a towel once out of the water. The Plié 3 MPC Knee
should not be immersed in saltwater or chlorinated water as
these may cause corrosion. Failure to comply will void the
warranty.
If unintentionally exposed to chlorinated and/or salt water
environments, the knee should be rinsed with fresh water.
While the Plié 3 MPC Knee withstands moist environments,
excessive use in wet conditions may result in corrosion and/
or undesirable operational noise. If the knee requires general
cleaning, wipe the outside surfaces with a cloth and rubbing
alcohol. For further information about how to care for you Plié
3 MPC knee, please contact your prosthetist
If the Plié 3 MPC Knee is physically damaged or
does not function properly, immediately contact
your prosthetist.

• High elevations and cold temperatures will aect the knee’s internal air pressure. In
these conditions, you may be required to increase the air pressure to resume normal
function.
• Without power, the Plié 3 MPC Knee will not release into swing phase. In this
powered-down mode, the knee will default to the stance exion resistance setting.
Insert a charged battery to resume normal knee function.
• Use only the batteries and battery charger intended for use with the Plié 3 MPC Knee.
• During repetitive activities without swing phase, such as the use of exercise
equipment, turn the stance exion resistance setting counterclockwise to the
“O” position with a 4 mm allen key. After the activity, adjust the stance exion
resistance to its previous setting.

Inserting Batteries
1. To Open: Press down latch. The cap will spring open.
2. Insert the battery, aligning the red dots. Be sure to properly fold
down the top portion of the battery label to ensure water
tightness. Also, be sure the gasket on the bottom side of the cap
is clean and free from dirt and debris.
3. Close the battery compartment by pressing firmly on the entire
cap until latch engages.

Charging Batteries
For optimal performance, alternate batteries every day. To charge, align
the red dot on the battery with the red dot on the charger. A 12V car
charger is also included.
The Status LED will illuminate red if the charger has power. The Charge
LED will illuminate red , indicating the battery is charging. When the
battery is completely charged, the LED will illuminate green . If the Charge
LED stays red for more than four hours, this indicates that the battery is
either damaged or worn out. The temperature of the battery should be
kept between 8 °C and 38 °C (46 °F to 100 °F) while charging. If the
temperature goes outside this range, the Charge LED will shutoff
indicating that charging was stopped before the battery was fully
charged.

air cap actsasa second seal to minimize air pressure loss.

Inserting Batteries
1. Pull the small tab in the middle of the cap towards you. The
indicator will change from green to red.
2. Push down on the cap and slide it to your right. Both indicators
now show red.Lift the cap to open.
3. Insert the battery, aligning the red dots. Be sure to properly fold
down the top portion of the battery label to ensure water
tightness. Also, be sure the gasket on the bottom side of the
cap is clean and free from dirt and debris.
4. Close the battery compartment by pushing the cap down and
sliding it to the left. The indicator shows green.
5. Push the small locking tab in the center of the cap forward. The
indicator will now show green and the compartment is securely
closed.

Adjustment of Swing Flexion Resistance
The Plié®3 MPC Knee provides swing exion resistance to limit
heel rise during walking. Excessive heel rise limits your ability
to walk at variable cadences. The swing exion resistance can
be increased or decreased by changing the air pressure in the
hydraulic cylinder. A higher air pressure provides more swing
exion resistance and is more eective for limiting heel rise.
Over time, the air pressure in the hydraulic cylinder will decrease,
resulting in a performance change. To ensure the knee provides
appropriate swing exion resistance, periodically check the air
pressure and add as needed.
To check the air pressure in the hydraulic cylinder, remove the
plug by pushing in the white release ring and pulling on the soft
plastic tab on the side of the plug. Attach the air pump by gently
inserting the tip of the adapter into the port. Push the pump
adapter tip gently and rmly into the port, it will stop when fully
inserted. Using the air pump, increase the air pressure to the
value recommended by your prosthetist. If you add too much air
pressure, it can be decreased by pressing the air pump relief valve under the gauge
on the pump. The knee should be used with the air pressure between 20 and 100 psi
(140 to 690 kPa). Remove the air pump by pushing in the release ring and gently
pulling the tip out of the port. Insert the air plug, pushing rmly and gently until
it bottoms out.
The pump’s pressure gauge always indicates the air pressure inside the knee. However,
when the air pump is connected, about ½ of the pressure in the knee will ow into
the pump, and the pump gauge will read ½ of what was in the knee. For example,
if the pump’s gauge indicates 15 psi at the time it is connected to the knee, the knee
had about 30 psi of air pressure before connecting the pump. Air pressure in the knee
does not drop when the air pump is disconnected. For example, if the pump’s gauge
indicates 30 psi before it is disconnected, the knee will still have 30 psi of air pressure
after disconnecting the pump. When the air pump is removed from the knee, a sound
of air leaking may be heard. This sound is air expelling from the pump hose to the
atmosphere.
Except when adjusting the air pressure, the air cap should remain inserted. The air
cap prevents lint and other debris from contaminating the air valve. Additionally, the
air cap acts as a second seal to minimize air pressure loss.
