After injury or surgery, or throughout the rehabilitation period, this knee immobilizer supports healing and protects the knee by controlling movement. It restricts leg movement and keeps the knee straight, preventing continuous bending and reducing strain on the surgical site or injured knee. The knee support brace features a semiopen design for easy observation, with a plastic hoop and padded opening to provide comfort without trapping heat or feeling bulky. Built for reliable performance, the design combines durable components with a breathable, comfortable fit to wear during extended recovery periods. Adjustable to fit different knee sizes and shapes, with straightforward application and removal to suit ongoing rehab protocols and daily use. Use scenarios: Postoperative immobilization after ACL reconstruction, meniscus , or other knee surgery to protect sutures and promote proper healing while allowing controlled ROM as prescribed. Early rehabilitation following knee injury or ligament strain where immobilization and precise extension limits help reduce pain and protect healing tissue. Rehabilitation phases that require gradual ROM progression, enabling clinicians to set specific extension or flexion limits and maintain proper knee alignment. Benefits at a glance: targeted immobilization, comfortable semiopen design, adjustable sizing to support healing and recovery.
