The new Ratchet POP Knee Brace by RCAI is designed for post surgical ROM limitations, ligament repairs, instability and soft tissue contractures. The Ratchet POP Knee offers flexion/extension ROM control in 5° increments, while featuring a ratchet type mechanism that allows incremental, locked positioning. With the flip of a lever, the angle of the limb can be extended in 10° increments from 60-0° without the use of settings or tools. The knee cap of the Ratchet POP Knee provides 3-point pressure leverage. The brace is constructed of a breathable, washable, one-piece liner that "wicks" moisture away from the body, keeping skin dry and comfortable. Hinges may be ordered separately by the pair for custom bracing. Product Length 18 1/2" (47 cm)
