How to use Unloader One Knee Brace?

  • Place the brace on patient‘s leg. Align the center of hinge at mid patella and midline of A/P.
  • Place button of lower Quick Fit Buckle into appropriate keyhole above Buckle Stability Shelf and close carefully using the palm of the hand to snap the buckle closed.
  • The button is color matched with an identical blue color in the keyhole for intuitive strap selection.

  • Quick Fit Buckles may have to be opened to relieve strap tension and allow positioning of strap pad on non-ratcheted DFS strap. Remove Upper DFS strap with dosing ratchet and feed strap through strap pad.
  • If patient requires more or less unloading, adjust the tension of upper DFS strap accordingly with Dynamic Force Control System and/or lower DFS strap by adjusting length at thigh Quick Fit Buckle.
  • If Dynamic Force Control System has been pulled to its maximum and patient requires more pain relief, DFS straps may require shortening at the lower Quick Fit Buckle.
  • Keyhole locks may be inserted into calf and thigh shells if desired to ensure straps cannot accidentally be disengaged from shells
