protect.4 OA
Intended purpose
protect.4 OA is a brace for varus/valgus
pressure relief. The product is exclusively
to be used for the orthotic fitting of the
knee and only on unbroken skin.
Indications
• Conservative treatment of complex
ligamentous instability, particularly in
combination with unilateral medial or
lateral osteoarthritis
• Postoperative pressure relief and
compartmental protection after
fractures of the tibial head, cartilage
surgery, meniscus refixation,
correction osteotomy
• Instability of the cruciate ligaments
with pressure relief on the medial or
lateral compartment
• For functional pre- or postoperative
care of knee instabilities
Contraindications
Medial and lateral osteoarthritis
Setting the flexion / extension limits
Extension limit wedge (limits extension):
0°, 10°, 20°, 30°, 45°
Flexion limit wedge (limits flexion):
0°, 10°, 20°, 30°, 45°, 60°, 75°, 90°
Can be immobilised at:
0°, 10°, 20°, 30°, 45°
The medial (inside) and the lateral
(outside) wedge settings must always be
the same.
1. 10° extension wedges are pre-
installed in your knee brace as
standard. They are found in the front
aspect of the brace's hinge joint.
2. To replace the wedges first loosen the
screws in the joint cover, then take the
cover off.
3. To change the silver extension wedge
loosen the screw and pull the wedge
out from the front of the joint. You
will find the replacement wedge in
the wedge set. It is marked with the
corresponding wedge setting. Slide
the new extension wedge into the
front of the joint. Now replace the
screw in the threaded hole and screw
it tight.
4. The flexion wedges are installed from
the back of the joint. Select the
suitable wedge from the wedge set.
Insert the wedge and secure it with
the appropriate screw (enclosed).
5. Bend and flex the brace 'joint' a
couple of times and check that the
wedges are positioned correctly.
Finally, secure the joint cover.
Important notes
Only change the extension and flexion
limits on instruction from your doctor or
orthotist to do so.
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.

Fitting instructions

• Open all the straps. Sit on the edge of a
chair, pull the brace up the affected leg
and flex your knee to 45°. Position the
joints so that the centres of the hinges
(extension wedges) are about 2,5 cm
above the kneecap and slightly past
midline of the leg. Make sure that the
brace is not twisted on your leg.
• First fasten the lower front calf strap
