The Flex POP Knee Orthoses by RCAI provide rehabilitation for joint stiffness and contractures, instability, strains, sprains, and ligament repairs. Constructed of a breathable one-piece Ortho- Wick liner, the lightweight brace absorbs perspiration and moisture away from the patients' skin, keeping them cool and comfortable. The versatile Flex POP features Range of Motion (ROM) hinges, with flexion and extension stop settings at 5° increments. The hinge arms are positioned in medial/lateral panels to prevent migration on the leg. Straps are sewn to the brace liner to prevent loss in the laundry.
