Detailed description

SpryStep® OA Knee Orthosis (KO) is designed to provide targeted support and relief for individuals suffering from knee osteoarthritis.

This knee orthosis is custom-made from a digital scan of the patient's leg, ensuring a precise fit that enhances both comfort and effectiveness. 
Its composite structure combines strength and lightness, making it durable yet easy to wear.

The brace features an adjustable 3-point leverage system, known as Loadshifter technology, which can provide up to 9° of correction in varus or valgus alignment. This system helps to offload the knee, reducing pain and improving function. Additionally, the TM5+ hinge mimics the natural movement of the knee, offering ligament stabilization and motion control with adjustable extension and optional flexion settings.

Cycle-testing independently performed under ISO 10328 Servo-Pneumatic Test System 
A2S biomechanical study "Biomechanical study of the stride during use of different braces" 2020 on similar Rebel(r) device.
