INSTRUCTIONS FOR USE Page 2 of 3
This de ice is exclusi ely intended to be used as prosthetic equipment for patients who ha e undergone
transfemoral amputation, hip disarticulation or knee disarticulation. It is specifically recommended for acti e
to ery acti e patients (L3/L4) as it allows them to carry out their e eryday acti ities on all types of terrain
as well as negotiate slopes and stairs.
Maximum weight (including carried load): 150 kg
Not suitable for children.
The maximum flexion of the knee is 120°. This flexion may, howe er, be limited by the olume of the socket or by the cosmetic co ering.
4. CLINICAL BENEFITS
The de ice allows:
•The patient to walk down stairs and slopes by bearing weight on the amputated leg to limit the effort on the sound leg.
•The knee to be locked in flexion using a manual lock to allow certain acti ities to be performed safely (e.g. climbing a ladder).
•The prosthetist/orthotist to adjust certain settings to adapt the knee to the patient.
•Walking at different speeds thanks to the hydraulic regulation.
•The hip to do less work since some of the knee extension force is pro ided by an extension assist spring.
5. OPERATION/INSTR CTIONS FOR SE
A. se in Lock mode
The knee is fitted with a lock which can be acti ated when you are standing or sitting. It pre ents all knee
flexion and is useful when climbing a ladder, for example.
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.
6. DETECTING ANY MALF NCTIONING
If you notice that the de ice is beha ing abnormally or if its characteristics feel different, or if it has been badly knocked, consult your
prosthetist/orthotist.
7. WARNINGS, CONTRAINDICATIONS, SIDE EFFECTS
A. Warnings
Caution, a knee with an electronic braking mechanism does not beha e 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 ad isable 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 a oid the any injury caused by the mo ement 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 ery 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
Your knee has been set up by your prosthetist/orthotist; you must not change these adjustments, since this might result in a fall
or lead to a serious malfunction of the knee.
The following are strictly prohibited: remo ing the co ers, screwing in or unscrewing any screws on the knee. If any play or
looseness de elops or your knee starts to malfunction, please arrange to see your prosthetist/orthotist.
Ne er 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 o erloaded, 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.
