The OA Knee Brace is a hinged unloader brace for one knee. Rigid thigh and calf shells work with a hinge and a pad at the side of the knee to shift load away from the inner (medial) or outer (lateral) side of the joint, whichever side you set it for. Swap-in angle blocks in the hinge let you limit how far the knee bends. Use it as advised by your doctor or physiotherapist.
Key benefits
- Unloader design shifts load away from the inner or outer side of the knee, set for the side you need.
- Swap-in angle blocks in the hinge let you limit how far the knee bends and straightens.
- Padded, vented thigh and calf shells hold the brace in place with four adjustable straps.
- Quick-release buckles let you put the brace on and take it off quickly.
How an unloader brace works

A knee cap or sleeve compresses the whole knee. An unloader brace works differently: it presses at three points to take load off one side of the knee.
- Thigh shell presses on the thigh.
- Calf shell presses on the calf, on the same side.
- The pad at the hinge presses on the opposite side of the knee.
Together they gently guide the knee so that less of your weight passes through one side of the joint. You choose which side, inner or outer, when the brace is set up.

Features
- Made for one side: each brace is made for either the left or the right leg, and the thigh shell is marked with its side.
- Inner or outer setting: the brace can be set to unload the inner (medial) or the outer (lateral) side of the knee.
- Angle adjustment blocks: small blocks slot into the hinge to set limits on bending and straightening. A set of blocks comes with the brace.
- Condyle pad: a soft pad at the hinge rests against the side of the knee for comfort and a steady fit.
- Four straps with quick-release buckles: two thigh straps and two calf straps; the buckles open and close without changing your strap setting.
- Low-profile, vented shells: slim shells with ventilation slots and a padded lining.
