3. Position the knee so that the alignment reference line passes through
midtube (A)
4. On the lateral side of the socket, make a first mark at the midpoint of
the socket at the ischial tuberosity level (D). Make a second mark at
the midpoint of the socket distally (E). Draw a line through both
marks.
5. Position the socket so the alignment reference line (B) goes through first
mark at the midpoint of the socket at the ischial tuberosity level (D).
6. Adjust the socket flexion to 5° in addition to the existing position (i.
e., hip flexion contracture) and set the height of the full prosthesis.
7. Use the applicable adapters to connect the knee to the socket.
Warning: After adjustments, all screws must be secured with a medium
strength threadlocker and tightened with the correct torque.
Caution: Adapters used on the distal connection must be cut straight and
inserted down to the end stop of the device's tube receiver. No spacer
should be used (Fig. 2).
Tighten the screws with the following torque:
• Tube Clamp Screw (Fig. 3): 16 Nm
Static Alignment
– Make sure the patient stands with equal weight on both legs.
– Check for correct prosthesis length.
– Check internal / external rotation.
– Check for correct load on toe and heel.
Dynamic Alignment
Ensure the patient is familiar with the functioning of the device.
Ensure the patient can activate and deactivate the geometric lock.
Adjustment of stance phase stability (Fig. 4)
Stance phase stability can be adjusted by altering the 5 mm Geometry
Screw (A) to change axial arrangement according to the following:
– To increase stance phase stability: turn the 5 mm Geometry Screw
to the left
– To allow for more dynamic gait: turn the 5 mm Geometry Screw to
the right
Always check the result right after each adjustment step.
Swing control
Adjusting the Extension Assist Spring (Fig. 5):
Turn the Extension Spring Adjustment Screw (A) to the:
• right to increase the action of the Extension Spring.
• left to decrease the action of the Extension Spring.
Adjusting axle friction (Fig. 6):
Turn the Friction Screw (A) to the:
• right to increase friction on the axle.
• left to decrease friction on the axle.
USAGE
Cleaning and care
Wipe the device with a soft cloth. Do not use solvents.
