4.1 Alignment

Careful attention to the alignment of the socket in relation to the Plié® 3 MPC Knee and the

prosthetic foot is essential for a successful user outcome. The prosthesis alignment should

account for the range of motion (ROM), voluntary control, and balance of individual users.

Proper alignment and user voluntary control are essential to the optimal function of the

prosthesis.

Prior to assembly of the prosthesis, the prosthetist should measure the patient's hip joint range

of motion (ROM) on the prosthetic side to determine if the user has a hip flexion contracture

(Figure 1). If present, the user's hip flexion contracture should be accommodated by attaching

the socket to the prosthesis with an appropriate amount of flexion (Figure 2). Failure to

sufficiently accommodate a hip flexion contracture can compromise the patient's function

during standing and ambulation (Figures 3 and 4).

During standing, an unaccommodated hip flexion contracture may prevent the patient

from standing straight, compromising the patient's balance (Figure 5). Additionally, an

unaccommodated hip flexion contracture can cause excessive lumbar lordosis,

compromising the structural integrity of the patient's spinal column (Figure 4).

During ambulation, an unaccommodated hip flexion contracture can cause an

excessively asymmetrical gait pattern.

4.2

The Plié® 3 MPC Knee should be in a fully extended position during stance phase for level

ground ambulation. An inherently stable trochanter-knee-ankle (TKA) alignment is essential to

a successful user outcome with the Plié MPC Knee. The referenced trochanter on the lateral

socket should be placed on or up to 5mm anterior to the knee joint axis (Figure 5).

An inherently unstable trochanter-knee-ankle (TKA) alignment can cause a rapid

extension moment at the knee joint after mid stance. The non-adjustable stance

extension resistance could 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 3 MPC Knee may differ

from other knee joints. Consequently, if a new socket is not fabricated for use with a

Plié 3 MPC Knee, the socket attachment component may require re-lamination to the

socket to achieve the recommended alignment

4.3.1 Instruct the user to stand between parallel bars.

4.3.2 With equal weight on each limb, adjust the height of the prosthesis as necessary.

4.3.3 Ensure the trochanter-knee-ankle (TKA) alignment follows the recommendations of

inherent stability.
