APPLICATION INFORMATION:
PRE-APPLICATION (performed only at initial fitting): With the patient standing, apply the brace frame to the leg without applying the straps. Adjust the brace’s varus / valgus alignment to fit the patient’s leg contours by adjusting the screws located immediately above and below the hinge with the enclosed Allen wrench (Fig 1).
The screws will feel loose when a neutral brace position is achieved. Continue to adjust the screws to achieve the desired load.
APPLICATION:
A) While seated at the edge of a chair, flex knee to 45° and slip on brace (Fig 2).
B) Center the hinges 1 inch (2.5 cm) above the top of the knee cap and slightly behind the midline of the leg and attach straps #1 and #2 (Fig 3).
C) Push both hinges toward the back of the leg and then attach strap #3 (Fig 4)
D) Draw the hinges forward slightly, but not beyond the midline of the leg, and attach the anti-migration band. Then attach straps #4 and #5 (Fig 5)
For OA Nano and 4Titude OA Nano, anti-migration band will need to be applied, located in accessory bag. See antimigration band application instructions.
E) T he hinges should center just above the top of the knee cap and slightly behind the midline of the leg (Fig 6).
F) Once the brace is on, perform knee bends and walk around to verify no brace slippage occurs (Fig 7).
If necessary, tighten the straps in the numbered order. The strap lengths can be adjusted beneath the strap pad (Fig 8).
STRAP PAD APPLICATION (FOR OA NANO ONLY): For additional comfort, five (5) strap pads are included in the accessory bag. These are placed internally on each strap (via Velcro attachment) to enhance overall fit and comfort.
ANTI-MIGRATION BAND APPLICATION: The anti-migration band is used to enhance brace suspension (if needed). Separate application instructions are located in the accessory bag or the OA Nano and 4Titude OA Nano users. The anti-migration band is already attached on all OA Adjuster versions. If removed, please reference the application instructions to reapply.
HINGE STOP INSTALLATION INSTRUCTIONS : Detach both condyle pads. Insert 10° extension stops into the front of both hinges. Insert and tighten supplied screws into both hinges (Fig 9).

CLEANING INSTRUCTIONS : Regular Cleaning of components is recommended. A dry lubricant such a TeflonTM spray may be applied to the hinge’s internal mechanism and is recommended following use in water. Inspect the hinge screws periodically and tighten if loose.
