Kicker braces are a type of orthopedic device used to stabilize and support the knee joint. They are commonly used after an injury or surgery to the knee, or in cases of arthritis or other degenerative conditions. Kicker braces typically consist of two metal bars that extend from the thigh to the calf, and are connected by adjustable straps. The bars can be adjusted to provide different levels of support depending on the needs of the patient.
