8.1.8 Checking the socket after bench alignment

At the end of dynamic alignment optimisation, verify that the minimum distance of the socket to the knee joint has
not been exceeded at maximum extension and maximum flexion. A collision of the socket with the hydraulics or
frame can cause damage to the knee joint.

8.1.9 Flexion stop

The knee joint comes fitted with a flexion stop upon delivery. This reduces the maximum flexion angle by 15°, thus
preventing the socket from coming into contact with the hydraulic unit.
To limit the flexion angle, the knee joint can be equipped with the following flexion stops:
• 4H99 flexion stop (in scope of delivery): Reduction of the maximum flexion angle by 7.5°
• 4H100 flexion stop (already installed): reduction of the maximum flexion angle by 15°
• 4H103 flexion stop (optional accessory): Reduction of the maximum flexion angle by 22.5°
The flexion stop can be removed to increase the flexion angle. In this case, it must be ensured that the socket and
the hydraulic unit do not collide (see Page 70).

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.
If the distance between the socket and sealing sleeve is not sufficient, the frame may
be damaged. Check the distance as follows:
1) Bring the knee joint with socket to maximum extension.
2) Check the available distance between the sealing sleeve and socket. It must be
at least 5 mm.
For fittings with the Genium protector, the distance must be at least 10 mm.
