of the knee
D. Finishing
It is advisable to reinforce the cosmetic cover in front of the joint to extend its service life.
If worn without a cosmetic cover, the protective hood supplied may be affixed to the knee,
using adhesive (XC050).
The cosmetic cover may modify the knee's initial 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 knee's covers, notably the posterior band which protects the
hydraulic system when the knee is fully flexed.
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.
8. WARNINGS, CONTRAINDICATIONS, SIDE EFFECTS
A. Warnings
Caution, a knee with an electronic braking mechanism does not behave like a braked knee; the patient may need some time to get
used to a new knee when switching between the two.
To reduce the risk of falling when going down stairs, it is advisable to hold on to handrail.
If the knee is not used for a few hours, it may make a clicking or cracking noise when first used. This does not impair its operation.
So as not to damage the knee, do not apply talcum powder to eliminate rubbing noises - use silicon spray instead. Talc degrades
the mechanical components, which might cause a malfunction and possibly a fall.
PROTEOR disclaims all liability if talcum powder is used.
It is possible to trap a finger or pinch clothing in the knee joint. To avoid the any injury caused by the movement of the joint, make
sure that no-one's hand or fingers is near the mechanism.
If the knee is immobilised for a prolonged period is very cold conditions (<10°C), the hydraulic system will not return to normal
operation until the patient has completed a few steps. Walk carefully until it feels normal again.
The knee is resistant to bad weather, but needs to be dried if it does get wet.
B. Contraindications
The following are strictly prohibited: removing the covers, screwing in or unscrewing any screws on the knee with the exception of
the four adjustment screws (R, S, F and E) and the two tightening screws (V1 and V2) on the Ø34 tube clamp adapter.
Never lubricate the knee pins; this might cause them to degrade rapidly.
The knee has been designed for patients with a maximum weight of 150 kg (including carried load). If overloaded, a safety feature
releases the hydraulic system which can lead to rapid flexion of the knee.
If a load is being carried, the operation of the knee may be disrupted. Particularly, the resistance when going down stairs may be
insufficient, or the knee may lock up suddenly.
If the patient's weight increases significantly, he or she should arrange for the prosthetist/orthotist to readjust the knee's safety
settings.
INSTRUCTIONS FOR USE
Maximum flexion stop
When fully flexed, the socket may come into contact with the posterior band, located above
the adjustment buttons.
The socket must not come into contact with the hydraulic system since this might damage
or degrade the knee.
The knee is fitted with an internal stop which limits its flexion to 120°.
Lock
The HYTREK knee is fitted with a lock which can be activated when the patient is standing or
sitting.
To lock the knee, press on the button at the rear of the knee. Always check that the lock has
been engaged before applying load to the knee. Press on the button next to the lock button
to unlock the knee.
