2. DESCRIPTION, PROPERTIES AND MECHANISM OF ACTION
A. Description
A single-axis knee offering hydraulic regulation of the stance and swing phases, fitted with a manual lock that halts
the flexion of the knee.
It is available in four different versions:
•
1P130/1P131: Male pyramid proximal connector, suitable for patients who have had a transfemoral amputation or hip
disarticulation
•
1P130-KD/1P131-KD: Threaded proximal connector (M36×1.5), suitable for patients with a long transfemoral amputation stump
or who have had a knee disarticulation
For all 4 versions, the distal connection is made via a Ø34 mm tube

Maximum patient weight
(Including carried load)
150 kg
This device has undergone a three-million-cycle test, in accordance with standard NF EN ISO 10328 at a P7 load level (i.e. 150 kg),
which corresponds to a service life of 4 to 5 years, depending on the patient’s mobility level.
C. Mechanism of action
The knee contains an oil-filled hydraulic cylinder.
The hydraulic system and the control of its operation provide safe management of the stance phase (transition after the swing phase
and resistance to flexion) and the swing phase (impact at the end of extension and dampening of flexion).
The angle of flexion of the knee is limited mechanically to 120°. This amplitude lets the patient kneel down and ride a bicycle.
It offers four separate adjustments, extension assist and a system for locking the flexion.
The knee’s intrinsic characteristics (flexion, braking, hydraulic regulation) allow patients to negotiate slopes and stairs using alternating
feet. As a precautionary measure, it is advisable to hold on to the handrail when walking down stairs.
The braking torque when descending stairs is high (150 Nm) up to a significant flexion angle (75°). This torque gradually reduces as the
flexion angle reduces.
Simply by pressing on a flexion locking button, the knee can be locked to prevent any flexion. With regard to extension, the lock halts
the flexion and allows the knee to extend. The patient can thus lock the knee to make it easier to negotiate obstacles, stand without
tiring and perform activities safely (e.g. climbing up a ladder).
3. PRESSING A SECOND TIME ON THE BUTTON UNLOCKS THE KNEE. INTENDED USERS/INDICATIONS
This medical device is supplied to healthcare professionals (prosthetists/orthotists) who then instruct the patient in how to use it. The prescription
is drawn up by a doctor. The doctor works with a prosthetist/orthotist to assess whether the patient is suited to using the device.
This device should be used on ONE PATIENT ONLY. It must not be reused on other patients.
