The Rapid Knee utilizes an adjustable ROM hinge and an open wrap configuration to provide convenience and comfort to the user. The wrap fits snugly and provides even compression and support. It has double upright ROM hinges and a locking joint for positioning the knee. The adjustable flexion and extension joint enables the practitioner to set limits on flexion and extension but allows the patient to move the knee freely within those limits. Portable, comfortable and easy to use, it is made with breathable, non-allergenic, and lightweight materials.
