PREPARATION:
Do not wear the brace over clothes. Carefully cut off the attached plastic bag with the extension
and flexion parts and set aside.
APPLICATION:
1. Open all closure straps, leaving the brace open. Sitting on the edge of a chair, step into the
brace with the upper thigh aluminum frame on the front of the leg and the lower calf
aluminum frame on the back of the leg. Flex your knee to 45 degrees. Position the joints
(covered condylar hinge pads) so that the center of the hinges are level with the top of the
kneecap.
2. First, find the front calf straps. Fasten the lowest front strap around the front of the calf.
3. Next, find the uppermost thigh strap on the back of the brace and fasten. Keep your knee
in a flexed position and push both brace joints toward the back of the leg, aligning the knee
to the hinge.
4. Find the lower thigh strap in the back and fasten. Ensure that the hinge joints are not
sitting in front of the midline of the leg.
5. Next, find the upper calf strap (5a) at the front and fasten. Find the upper calf strap (5b)
in the back and fasten.
6. Finish by fastening the lower thigh strap (6a) in the front. Each strap includes a gripping
comfort cushion. Place the gripping comfort cushion as desired for a secure and snug fit
on all six (6) straps, to keep the brace in the proper position (6b).
 Bend your knee slightly a few times and make any adjustment as needed.
 If the fit is too small or too large, or hinges are not properly positioned, unfasten,
adjust and refasten the straps again in the order described above to prevent the brace
from slipping. DO NOT OVERTIGHTEN.
7. ROM Hinge Adjustment: Using provided Screwdriver, loosen both screws on the outer
hinge cover. Per physician’s instructions, identify the correct Hinge Stops with correct
degree markers for the Flexion, Extension or both (see illustration below to identify the
hinge stops by markings on the back side of each). Insert the selected Hinge Stop(s) into
the correct side of the Hinge. Insert screws into holes and tighten until screw top is flush
with hinge plate cover. Repeat these instructions for the inner hinge cover.
