A Little about Osteoarthritis

The knee has 2 compartments, the inside (medial) compartment and the outside (lateral) compartment. Most of the time, when you get osteoarthritis of the knee, you wear down one compartment more than the other. In a majority of the cases, the inside of the knee wears down more, leading to a bowlegged appearance of the knee in extreme cases (medial compartment OA). Other times, the outside (lateral) compartment of the knee wears down leading to a knocked knee appearance of the knee (lateral compartment OA).

The Donjoy OA Nano Unloader brace is designed to take the pressure off the compartment that is more severely worn down. For this knee brace to be fully effective, It is important to figure out which knee compartment (medial or lateral)  is worn down more before deciding which OA Knee brace is right for you.  One of our physiotherapists can help you make this decision.  Feel free to contact us for help.

What Is an Osteoarthritis (OA) Unloader Knee Brace?

An osteoarthritis unloader knee brace unloads stress from the affected joint. Most often, unloader knee braces are prescribed for those with medial compartment knee osteoarthritis (affecting the inner portion of the knee).

When you walk, if you have medial knee osteoarthritis, the instability in the knee can be obvious to someone who is watching you walk -- the knee actually wobbles towards the inside. Usually the affected leg has a bow (bow legged, genu varus). Some designs of unloader knee braces can unload either the medial (inner) or lateral (outer) part of the knee -- just by adjusting the unloading hinge. This takes stress and unloads the side of the knee that has the arthritis, taking the pressure off and helping re-align the knee. This can help reduce pain, inflammation and help you walk better.
