- Rehabilitative braces limit knee range of movement of flexion and extension to reduce rotation after ACL injury or surgery.
- Unloader/off-loader braces are designed to unload stress from the injured knee joint by transferring the pressure on the thigh bone. It helps the knee to bend away from the injured and painful area. These braces are especially helpful for patients who want to take the pressure off their knees for pain relief.
