• If the user changes shoe heel height, the Plié Control Threshold Setting may require adjustment as the knee
requires a minimum user toe loading (adjustable Toe Threshold) to release into swing phase.
• During repetitive activities without swing phase, such as the use of exercise equipment, the user should turn
the stance flexion resistance setting counterclockwise to the “Off” position with a 4mm allen key. After the
activity, the user should adjust the stance flexion resistance to its previous setting.
• The Plié® 2.0 MPC Knee intended use does not include knee stance flexion gait on level surfaces. Failure to
adhere to the alignment recommendations may result in undesirable user gait characteristics on level
surfaces. As the stance extension resistance is non-adjustable, certain undesirable gait characteristics may
only be eliminated via alignment, user physical therapy, and/or user gait training.
• The intended use of the Plié® 2.0 MPC Knee is normal ambulation. If the user intends to run with the Plié
MPC Knee, the computer and manual settings may require adjustment for optimal running function.
• The user should avoid stepping backwards as the knee stability may be compromised.
• The userʼs socket should not contact the hydraulic cylinder. Failure to comply may result in cylinder damage
and will void the warranty.
•The Plié® 2.0 MPC Knee should not be submerged in water to depths greater than 0.5 m (1.6 ft). The user
should not intentionally expose the knee to water during activities such as showering, swimming, fishing, etc.
Failure to comply may cause corrosion and/or noise and will void the warranty.
• If exposed to chlorinated and/or salt water environments, such as walking along the shore, the knee should
be rinsed with fresh water.
• While the Plié® 2.0 MPC Knee withstands moist environments, continual use in wet conditions may result in
corrosion and/or undesirable operational noise.
• If the hydraulic cylinder shaft seal causes noise during user ambulation, lubricate the shaft with a few drops of
3-in1 oil.
• All purchased, serviced, and repaired Plié® 2.0 MPC Knees are sent to customers with the following default
hydraulic cylinder manual settings: swing flexion=30 psi, swing extension=0, stance flexion=5. Additionally,
the computer settings are sent to customers with default settings. The prosthetist should adjust the manual
and computer settings to meet the needs of each Plié® 2.0 MPC Knee user prior to use.
• The Plié® 2.0 MPC Knee is not field-serviceable and may only be repaired by Freedom Innovations, LLC.
Attempts to disassemble, repair, or modify the Plié® 2.0 MPC Knee, including changes to the tension on any
of the threaded fasteners, could put the user at risk for serious injury and will void the warranty.
• If applying talcum powder when donning the prosthesis, the user should take care to prevent the powder from
contacting the hydraulic cylinder shaft. Talcum powder may cause noise and/or acceleration of shaft seal
wear.
• A thin film of oil on the hydraulic cylinder is normal. Only return the Plié® 2.0 MPC Knee for repair if the oil
appears to be leaking from the hydraulic cylinder.
• Freedom Innovations, LLC is responsible for radio frequency compliance. Changes to any portion of the
wireless system not expressly approved by Freedom Innovations may void the user's authority to operate the
equipment.
• A wireless USB adapter is supplied with the Plié® 2.0 MPC Knee. While other wireless adapters may be
compatible, Freedom Innovations, Inc. only provides technical support for the supplied device.
• During wireless transfer of data files from the knee to the computer, the Plié® 2.0 MPC Knee will remain in
stance phase. Instruct the user to refrain from ambulating by sitting or standing during data file transfers.
• If the Plié® 2.0 MPC Knee causes harmful interference with other wireless devices, the user may alleviate the
interference by: reorienting, relocating, and/or increasing the separation distance between the receiving
device and the Plié® 2.0 MPC Knee. To determine if the Plié® 2.0 MPC Knee is the cause of interference,
remove and reinsert the battery.
