    How does it work?/Mode of action


    This orthosis is intended to help you to reduce stress on your knee. The orthosis is used in both postoperative therapy and in conservative (non-operative treatment). It protects the leg from swerving outwards. Stress is reduced on the painful areas of the knee joint and the orthesis brings a perceptible reduction in pain. Some patients only improve gradually.
