The Donjoy OA Adjuster Knee Brace is an arthritis knee brace that is clinically proven to off-load the knee and improve pain and stability while walking.  It's ideally suited for active adults with moderate to severe osteoarthritis on one side of the knee (uni-compartmental OA). The brace can reduce stress on the knee and help patients maintain their everyday activities. The OA Adjuster is made out of lightweight 2021 aluminum to provide the strength needed to impart three points of unloading to help reduce pain.  The OA Adjuster's unloading capability is easily controlled by adjusting the hinge with the provided hand-held tool (pictured below).   This is a great brace for use with work activities, sports, and just everyday walking.
