Dear Patient,
Your doctor has prescribed the
functional knee brace M.4s for you.
Please read through these
instructions carefully to help ensure
that you fit your brace correctly.
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°, 45°
Flexion limit wedge, black:
0°, 10°, 45°, 90°, 120°
Can be immobilised at:
0°, 10°, 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 change the wedges, simply remove
the joint cover.

3. Replacement extension wedges
(silver) can be found in the wedge set
marked 'R-E' and 'L-E'. Slide the new
wedge into the joint from the front,
and secure it by tightening the screws.
Insert the wedge so that the letter
shown on the joint plate points
upwards (R or L). Now insert the screw
in the thread and screw it tighten.
4. To replace the black flexion wedge
loosen the screw and pull the wedge
out from the back of the orthosis.
Select the suitable wedge from the
wedge set marked 'R-F' and 'L-F'. Insert
the wedge so that the letter shown on
the joint plate points upwards (R or L).
Now insert the screw in the thread
and screw it tighten.
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.
