How to Wear / Fit

  1. Sit down and extend the leg, Then release all strap tension: on braces with SmartDosing turn both dials counterclockwise to the 0 position, And on braces with the dosing ratchet press the button on the ratchet and move it to the 0 position
  2. Bend the knee to 90 degrees, Open the upper and lower buckles and pull the buckle buttons out of the keyholes
  3. To replace a DFS strap, Unfold the old strap from its alligator clip, Unthread it from the frame, Then thread the new strap the same way and fold it back into the clip
  4. To replace a popliteal pad, Position the pad flat where the DFS straps cross behind the knee and confirm it is not wrinkled
  5. To replace a condyle pad, Peel the worn pad off the inside of the hinge, Clean the surface, Then press the new pad on so it sits flush against the frame
  6. To renew liner attachment points, Remove the worn hook and loop tabs and press the new Liner Twist Fit Attachment Kit pieces onto the thigh and calf shells so the liners hold firmly
  7. To replace keyhole caps, Press each new cap into the thigh or calf shell keyhole until it seats flush
  8. To replace a hinge arm screw, Seat the screw in the hinge arm and tighten until snug, Do not overtighten
  9. Refit the brace with the hinge on the affected side, Align the Ossur logo on the hinge with the upper edge of the kneecap, Snap the blue lower buckle button into the blue calf shell keyhole, Then bend the knee to 80 degrees and snap the yellow upper buckle button into the yellow thigh shell keyhole
  10. Adjust strap length, Set the dials or the ratchet to the 5 position, Then trim the straps starting with the calf strap so the alligator clips sit away from the area behind the knee
