Osteoarthritis Knee Brace
INDICATIONS:
• Moderate to severe unicompartmental osteoarthritis of the knee joint combined
with ligament instability
• Cartilage surgery, chondroplasty, meniscus refixation, transposition osteotomy,
post-operative relief of the medial or lateral compartment
MODE OF ACTION:
Protection, stabilization, pain relief and restoration of mobility by:
• 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
• Stabilization of the knee joint to counteract knee instability which often causes
osteoarthritis
• Safeguards against hyperextension and offers limitation of flexion and extension
FEATURES:
• Reliable pressure relief from the 3-point principle with varus/valgus adjuster
• S-shaped frame and floating flexible D-rings ensure a snug and comfortable fit
• Innovative non-slip+ cushioning material for frame and strap pads achieve a greater
degree of patient comfort and compliance while optimizing migration control
• Patented flex bar allows transfer of force across the joint, removing pressure on
affected compartment
• Ultraflat, lightweight and low profile frame and hinge construction of Avional ®
alloy material which is 30% more rigid than other aluminum alloy technologies
of the same weight
