How does it work?

Commended for ease of use by the Arthritis Foundation, the Donjoy OA Assist Knee Brace features a single, upright OA frame incorporating a unique 3DF (3rd Degree of Freedom) hinge, which gives flexion and extension control, while minimising brace rotation. A telescoping condyle pad shifts compressive knee joint forces from the degenerative area to the healthy compartment.
Extremely comfortable and easy to use, the OA Assist is the ideal knee brace for patients who wish to carry on with their daily activities, as well as those whose lifestyle is more sedentary.
