C. Adjusting the walking pace
On delivery, the knee is set up for walking at medium pace (hex set screws E and F in their mid position, and extension assist cylinder
R screwed in to its maximum minus three turns).
For patient safety reasons, the prosthetist/orthotist must begin the adjustment process with the knee set to its factory settings and
with the patient walking between parallel bars.
The model of foot used may have an effect on the adjustment of the knee. The knee should be readjusted whenever the foot is changed.
Prioritise patient safety in all circumstances, particularly to ensure that slopes and stairs can be negotiated safely.
After performing any maintenance the knee must be readjusted.
To adapt the knee to the patient's pace of walking, adjust hex set screws E and F using an Allen (hex) key.
It is advisable to perform these adjustments in the following order:
1.
Adjusting the Flexion (F)
Turn hex set screw F: Screw in the set screw to reduce the angle of flexion, and
unscrew to increase it.
Adjustment range: 1 turn in the screw-in direction and 1 turn in the unscrew
direction
2.
Adjusting the Extension (E)
Turn hex set screw E: Screw in to cushion the impact when the knee reaches full
extension.
Adjustment range: 1 turn in the screw-in direction and 1 turn in the unscrew
direction
3.
Adjusting the extension assist (R)
If the optimal adjustment for the patient's walking pace cannot be achieved:
Adjust the extension assist cylinder R to change the assist power: Screw in for more powerful assist (faster extension) or
unscrew for less powerful assist (slower extension).
After adjusting the assist power, the Extension (E) setting must be checked.
Once these adjustments have been made, ensure that the knee returns to full extension when walking slowly to ensure that there is
no risk of the patient falling.
This hydraulic knee has been primarily designed to allow control during the swing phase. If, for example, the patient's body weight
bears on the hydraulic system with the resistance to flexion set to high, there is a danger of degrading the knee.
D. Finishing
It is advisable to reinforce the cosmetic cover in front of the
joint to extend its service life.
Maximum flexion stop:
When fully flexed, the socket (E) must never come into
contact with the linkages (A) and (B).
The socket must be restrained by the maximum flexion stop
(J) to preserve the knee.
The cosmetic cover may modify the initial knee settings and
limit certain movements. It is advisable to always check the
operation of the knee, once the cosmetic cover has been
fitted.
Do not remove any of the covers over the knee.
7. DETECTING ANY MALFUNCTIONING
If you notice that the device is behaving abnormally or if its characteristics feel different, or if it has been badly knocked, consult your
prosthetist/orthotist.
