Freedom Innovations Plie 2.0 MPC KNEE Instructions For Use Manual - page 16
!An inherently unstable trochanter-knee-ankle (TKA) alignment may cause a rapid extension moment at
!the knee joint after midstance. The non-adjustable stance extension resistance may be insufficient to
!dampen the extension moment if the user does not exert sufficient voluntary control and/or if the
!
alignment recommendations are not implemented.
"The recommended inherently stable alignment of the Plié® 2.0 MPC Knee may differ from other knee
!joints. Consequently, if a new socket is not fabricated for use with a Plié® 2.0 MPC Knee, the socket
!attachment component may require re-lamination to the socket to achieve the recommended alignment.
Static Alignment
Prior to ambulation, observe the overall alignment with the prosthesis donned on the user:
a. Instruct the user to stand between parallel bars.
b. With equal weight on each limb, adjust the height of the prosthesis as necessary.
c.
Ensure the trochanter-knee-ankle (TKA) alignment follows the recommendations of inherent stability.
d. Ensure the transverse rotation of the knee and foot is appropriate.
e. Instruct the user sit in a chair. Adjust the height of the knee joint axis to match the contralateral limb as closely
as possible.
!To prevent risk of injury to the user, perform the static alignment, dynamic alignment, and set-up between
!parallel bars.
Dynamic Alignment
Prior to Set-Up, allow the user to adjust to the prosthesis:
a. Instruct the user to take a lunge step with the prosthesis (Figure J). The lunge motion will allow the user to
feel the stance flexion resistance and develop confidence. Repeat as necessary.
b. Instruct the user to carefully ambulate. Teach the user to flex the ipsilateral hip extensor muscles at initial
contact to stabilize the knee joint.
c.
Train the user to load the prosthetic toe to initiate the swing phase transition.
d. Train the user to take steps of equal length.
e. Adjust the alignment in the transverse, coronal, and sagittal planes as necessary.
f.
Train the user to sit in a chair using the stance flexion resistance.
Set-Up
While the Plié® 2.0 MPC Knee may function adequately at the default settings, both the computer and manual
hydraulic settings should be optimized for each user. Follow the five steps below to set-up the Plié® 2.0 MPC
Knee.
1. Establish Wireless Connection
To optimize the microprocessor, communication must first be established between the programming computer
and the userʼs Plié® 2.0 MPC Knee:
a. Open the Plié Control software (Start>All Programs>Plié>Plié Control).
b. Insert the provided USB wireless adapter in any available USB port.
c.
Remove and re-insert the battery. Battery insertion activates the knee wireless module for five minutes.
d. Select the Search icon.
e. After the knee is found, select the Connect icon to establish a wireless connection. If the Connect icon
changes to a Disconnect icon, the wireless connection is verified.
!
If the software and knee do not appear to be communicating, select the Wireless Sync icon to re-
!
establish the wireless connection.
!
The green LED inside the knee frame only remains illuminated when the a wireless connection has been
!
established with a computer.
