4) Guide the lower leg strap through the strap guide loop, pull it taut and
close it at the hook-and-loop closure (see fig. 4).
5) Guide the thigh strap through the strap guide loop, pull it taut and close
it at the hook-and-loop closure (see fig. 5).
6) Ensure that the orthosis is in the correct position.
7) Optional: Adjust the corrective force; this changes the varus/valgus
angle of the orthosis (see fig. 6).
5.3 Adaptation
Adjusting the corrective force
Prerequisite: The patient should be seated.
>
Prerequisite: The knee joint should be relieved of pressure and slightly
>
bent.
1) Set the corrective force on the socket screw above the orthotic joint (see
fig. 6). This changes the varus/valgus angle of the orthosis.
2) Check the corrective force while standing and walking.
3) The corrective force can be optionally adapted until the desired adjust­
ment has been made.
Optional: limiting the knee flexion and extension
The extension limitation at delivery is 0°. The flexion is not limited.
1) Move the joint bars of the orthotic joint (see fig. 1, item 5) to maximum
flexion (see fig. 8).
2) Remove the condyle pad from the hook-and-loop pad (see fig. 9).
3) Pull the joint bars out of the lateral guides of the orthosis (see fig. 10).
4) To limit the extension, remove the anterior screw. To limit the flexion,
remove the posterior screw.
5) Choose the joint stops appropriate for the desired flexion and extension
limitation (see fig. 1, items 11 and 12).
6) Insert the joint stops into the orthotic knee joint. Insert the joint stop for
extension limitation at the front and the joint stop for flexion limitation at
the back. Ensure that the heads of the joint stops are pointing outwards
(see fig. 12).
7) Secure the joint stop with the screw (see fig. 11).
8) Insert the joint bars into the lateral guides, observing the installation dir­
ection.
9) Re-attach the condyle pad.
