Tynor D-09 Functional Knee Support is an orthopedic hinged knee brace designed to provide stability, protection, and controlled support to the knee joint. Its wrap-around construction and rigid bilateral hinges help control unwanted side-to-side movement while allowing controlled flexion and extension of the knee.

The brace features an open-front, wrap-around design that makes application easier, particularly when the knee is swollen or painful. Adjustable hook-and-loop straps allow the user to customize the fit and compression, while the breathable elastic fabric provides comfortable support during extended use.
