The areas of application are osteoarthritis of the knee, knee pain, bow-leg (varus) and knock-knee (valgus) deformities
Mechanism of action
Protection, pain reduction and restoration of mobility by means of:
- Relief of the medial or lateral joint compartment by means of a 3-point system that supports the joint to correct valgus or varus alignment
- Knee stabilisation by means of the 4-point principle, to counteract knee instability, which often causes osteoarthritis of the knee
- Protection against hyperextension and limitation of movement by means of adjustable physioglide hinges
Characteristics:
- Accurate and effective exertion of pressure near the joint to correct valgus or varus alignment.
- Flexible frame design to avoid torsional forces
- Mouldable thigh and lower leg frame to adjust to individual leg contours
- Polycentric physiological hinges using the principle of 4-chain linkage
- Possibility of limitation of extension at 0°, 10°, 20°, 30°, 45°
- Possibility of limitation of flexion at 0°, 10°, 20°, 30°, 45°, 60°,75°, 90°
- Possibility of immobilisation at 0°, 10°, 20°, 30°, 45°
- Ultra-flat, very light non-contact frame and hinge construction
- Well designed and easy to use strap guide
- Broad, well padded contact surfaces for the 3-point relief system
- Numbered straps, which make the fitting of the orthosis simple and accurate
- Air-filled condyle pads to prevent migratition.
- Excellent wearing comfort due to soft-grip padding material
- Fitted liner stocking available on request
