English
the two noses of the joint cover into
the front side of the joint and then
pushing the cover onto the joint. The
cover is firmly attached if you hear a
click sound.
Important notes
Only change the extension and flexion
limits on instruction from your doctor
or orthotist. In order to prevent
hyperextension, always insert extension
wedges or 0° wedges. The wedges define
the exact excursion of the orthosis. In
difficult soft-tissue conditions, e.g.
where the soft-tissues are under
compression, it may be necessary to
insert the larger wedge to limit the joint
movement to the desired excursion. In
addition, make sure that the orthosis
joints are correctly positioned: the
middles of the joints should be level with
the upper border of the patella. The joint
must lie behind the midline of the leg
(Fig.12).
Shaping the orthosis
When shaping the orthosis, please
ensure that the joints stay parallel. This
guarantees that the orthosis will
function well and run easily and that
there is no excessive wear.
Locking mechanism
WARNING! The locking mechanism only
works if a 0° extension wedge is
inserted. With other wedge settings the
lock mechanism does not work.
Fastening the belt eyes
The belt eyes have been adequately
fastened and are, to some extent,
deliberately mobile. Please do not
tighten the screws; they are tight
enough. If you apply too much force,
you can break off the screws.

Fitting instructions

Whenever possible, put on the knee
brace in the extended position. To do so,
set the knee brace to the extended
position and lock both joints by moving
the slider forward (you can see a red
area in the windows on the joints); see
Figures 1+2.
Open all the straps. Sit on the edge of a
chair and put the brace on. Position the
brace so that the centre of the hinges
(silver wedges) are on a level with the
top edge of the kneecap (Fig. 9). Make
sure that the brace is not twisted on
your leg.
First fasten the lower front strap #1 (Fig.
4), then the upper rear thigh strap #2
(Fig. 5). Position the two joints close to
your joint towards the front of the leg
(Fig. 6).
Now fasten the lower rear thigh strap #3
(Fig. 7). Pull the joints slightly forward
again. Make sure that you do not pull the
joints in front of the midline of the leg.
Now fasten the upper front calf strap #4
(Fig. 8), then the upper back calf strap #5
(Fig. 9 + 12), and finally the front thigh
strap #6 (Fig. 10).

Care instructions

The pads are water-repellent;
nevertheless, they should be wiped off
and dried briefly after you take a shower
– the same applies to the straps. Soap
residues, lotions and ointments can
cause skin irritation and material wear.
• Do not bleach.
• Leave to dry naturally.
• Do not iron.
• Do not dry clean.
With normal use, the hinge mechanism
should not require any maintenance, but
it can be lubricated with Teflon spray.
Check regularly that the joint screws are
secure, tighten them if necessary.
