English
protect.4 evo
Intended Purpose
The protect.4 evo is a functional knee orthosis.
The product is exclusively to be used for the
orthotic fitting of the knee and only on intact
skin.
Indications
• Ruptures of the anterior or both cruciate
ligaments with accompanying injuries
• Isolated ruptures of the anterior cruciate
ligament
• Ruptures and/or instability of the collateral
ligaments
• After reconstruction of the anterior or both
cruciate ligaments
• For conservative treatment of knee joint
instability
Contraindications
None known at present.
Setting the flexion / extension limits
Extension limit wedge, silver:
0°, 10°, 20°, 30°, 45°
Flexion limit wedge, black:
0°, 10°, 20°, 30°, 45°, 60°, 75°, 90°
Can be immobilised at:
0°, 10°, 20°, 30°, 45°
For immobilising the orthosis first insert the
flexion wedge and then the corresponding
extension wedge. The medial (inside) and the
lateral (outside) wedge settings must always be
the same.
1. 10° extension and 90° flexion wedges are
pre-installed in your knee brace
as standard (In the UK only 10° extension
wedges fitted, remainder included as spare
parts).
2. To replace the wedges first loosen the screws
in the joint cover, then take the cover off, the
wedges can now be removed by being gently
pulled out in a forwards direction.
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. 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.
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.
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

• 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
