4-point knee orthosis for control of anterior and posterior tibial translation. 3-point off-loader for varus or valgus pressure relief
Indications
- conservative treatment of complex ligament instability, particularly in combination with unilateral osteoarthritis
- conservative treatment of advanced unilateral osteoarthritis
- post-operative pressure relief and compartmental protection after fractures of the tibial head, cartilage surgery, meniscus refixation, correction osteotomy
- instability of the cruciate ligaments with pressure relief of the medial or lateral compartment
- for functional pre or post-operative care of knee instabilities
Mode of action
- protection, stabilisation, pain relief and restoration of mobility
- pressure relief of the medial or lateral joint compartment by the 3-point principle which off loads the affected compartment into a varus or valgus position
- stabilisation of the knee joint by the 4-point principle to counteract knee instability, a cause of osteoarthritis
- safeguards against hyper-extension and offers limitation of flexion and extension
Features
- 'S' profile improves torsional stability whilst following natural alignment of femur and tibia
- hinges proximal to knee joint allow precise off loading of the knee
- polycentric hinges
- anatomically premoulded frame
- strong, low profile, light weight frame and hinge construction
- numbered straps ensure a simple fastening sequence
- air condyle pads with skin-grip system
- excellent comfort with new soft-grip padding material
- extension limitation at: 0°, 10°, 20°, 30°, 45°
flexion limitation at: 0°, 10°, 20°, 30°, 45°, 60°, 75°, 90°, 120°
immobilisation at: 0°, 10°, 20°, 30°, 45° - under sleeve and knee protector available
