Safety Precautions - Össur PASO Instrucciones Para El Uso

the 29 mm long central screw (4), and the IKF-Adapter(15) must be screwed tight with the 27 mm long central
screw (3). Safety requirement!
OPTIMISING THE PROSTHESIS ALIGNMENT
After loosening the respective central screw, unlimited rotation and A-P/M-L corrections of 5 mm are possible.
In addition, in the case of the Paso Knee with loop adapter, alignment corrections in flexion, extension, adduction
and abduction of up to a maximum of 10° are made possible through the use of adjustment discs (13).
Attention: in order to prevent any unwanted rotation and thus risk to the user, always make sure that the central
screw concerned (3, 4 or 5) is tightened to a torque of 35 Nm at the dynamic fitting session.
ADJUSTMENT
The Paso Knee knee joint is supplied by the factory in full working order with the basic settings. Carefully start
testing the function of the joint with the user at the dynamic fitting and check whether this basic setting suits the
needs of your patient. If not, please go through the following steps.
Stance phase stability
Adjustment by shifting the joint
In the basic configuration described here, the axial alignment gives high stance phase stability.
This can be adjusted to the individual needs of the patient by shifting the knee joint in the AP direction.
Shift the joint backwards
▸ safer alignment (fig. 3)
Shift the joint forwards
▸ more dynamic alignment (fig.4)
Adjusting the axle geometry
The axle geometry of the Paso Knee can be changed using interchangeable wedges. This allows the time of
transition from the stance phase to the swing phase to be adjusted to the user's desired need for safety.
The axle geometry can be adjusted in three different settings:
Joint without wedge (as supplied)
▸ high safety with A-P shifting
Joint with wedge A
▸ Safety without A-P shifting
Joint with wedge B
▸ highly dynamic
Paso Knee is supplied without a wedge. Wedge A and wedge B are available as accessories in the Dynamic Set (Art.
No. 1.970.970).
If necessary, the wedges are mounted on the back stub axle with two screws (9).
To change or remove the wedge (8) loosen the screws (9). After changing the wedge tighten the screws by hand
again and secure with Loctite. Use a 2 mm Allen key.
Mounting of the knee protection cap
The Paso Knee leaves the factory with a mounted knee protection cap. To remove the knee protection cap, loosen
the scrows at the bottom of the knee protection cap and pull the knee protection cap to the bottom of the knee.

SAFETY PRECAUTIONS

• The adapters used at the top connection must always be tightened to the specified torque for the modular
component concerned. Use a torque wrench.
• The adapters used for the lower connection (e.g. tube adapter) must be inserted down to the end stop in the
tube receiver of the knee joint.
