Setting the flexion / extension limits
Extension limit wedge (limits extension):
0°, 10°, 20°, 30°, 45°
Flexion limit wedge (limits flexion):
0°, 60°, 75°, 90°
Can be immobilised at: 0°
The medial (inside) and the lateral
(outside) wedge settings must always be
the same.
• 10° extension wedges are pre-instal-
led in your knee brace as standard.
They are found in
• the front aspect of the brace’s hinge
joint.
• 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.
• 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.
• 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).
• Bend and flex the brace ‘joint’ a couple
of times and check that the wedges are
positioned correctly. Finally, secure the
joint cover.
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 on a level with
the top edge of the kneecap. Make sure
that the brace is not twisted on your
leg.
• First fasten the lower front calf strap
(strap #1), then the upper back thigh
strap (#2). Keep your knee in a flexed
position and push both joints towards
the back of the leg.
• Now fasten the lower back thigh strap
(#3). Make sure that you do not have
the hinge joints positioned in front of
the midline of the leg.
• Now fasten the upper front calf strap
(#4). Then the upper back calf strap
(#5), and finally the front thigh strap.
• Bend your knee slightly a few times
and refasten the straps again in the
order described above to prevent the
brace slipping.
