Abstract: The Knee Immobilizer Support Cuff has been created as a medical apparatus for bottom based support for a knee immobilizer (brace). Knee Immobilizers are difficult to keep in the correct position and often slip down the patient's leg during upright orientation (standing/walking). The Knee Immobilizer Support Cuff will stabilize the knee immobilizer without having to overly tighten the straps, thereby avoiding the discomfort and restriction of blood flow to the knee and surrounding tissues. The knee immobilizer support cuff will be offered in a variety of sizes and/or shapes to fit the needs of the individual patient.
