Ensure the knee joint is in full extension during bench alignment. To do so, briefly push the socket once into the
fully extended position.

7.1.6 Static alignment optimisation

The adjustment software specifies concrete reference values based on measurement data to help optimise the
alignment.
A precondition is that the alignment recommendations were followed during bench alignment of the prosthesis.
The goal of optimised alignment is that the user must compensate as little as possible with their residual limb.
Optimised alignment of the prosthesis components can reduce the effort required from the patient.
INFORMATION
During static alignment optimisation, the knee joint is automatically locked in the flexion direction. This should
enable the patient to stand in a stable stance that is unaffected by the alignment. Patients can only walk with the
prosthetic leg fully extended in this situation!

7.1.7 Dynamic alignment optimisation

After adjusting the product with the adjustment software, perform dynamic optimisation during trial walking. Often,
the following aspects have to be observed and adapted, if necessary:
Socket flexion position by verifying step length symmetry (sagittal plane)
Adduction position of the socket and M-L positioning of the socket adapter (frontal plane)
Rotation position of the knee joint axis and outward rotation of the prosthetic foot (transversal plane)

7.1.8 Protective Cover Installation

1) Open the closures.
2) Spread open the Protective Cover.
3) Apply the Protective Cover to the knee joint.
4) Fasten the upper closure.
→ Squeeze the Protective Cover together slightly with both hands.
→ Push back the upper closure with your thumb.
5) Fasten the lower closure.
NOTICE
Loss of stability due to inadequately installed retainers
No hold of the Protective Cover on the knee joint.
► Ensure that all retainers and closures are properly engaged and/or fastened.

7.1.9 Checking the socket after bench alignment

After bench alignment, verify that at maximum extension and maximum flexion the distance from the socket to the
knee joint is not less than the minimum. A collision of the socket with the hydraulics or frame can cause damage to
the knee joint.
Verification at maximum flexion
Genium X3 3B5-3/3B5-3=ST
If the distance between the socket and hydraulics is not sufficient, the hydraulics
may be damaged. Check the distance as follows:
1) Bring the knee joint with socket to maximum flexion.
2) Check the available distance between the hydraulics and socket. It must be at
least 3 mm.
INFORMATION: If the distance is less, a flexion stop has to be installed or
an existing flexion stop replaced with a larger one. For information on the
flexion stop, see the next section.
