Indications

• conservative treatment of complex ligamentous 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

• 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

• exact and effective valgus or varus pressure exerted close to the knee joint
• wide, well cushioned frame padding for the 3-point pressure relief system
• malleable frame design to provide individual custom fit
• ultraflat, very light weight and non-protruding frame and hinge construction
• new Avional aluminum frame material is 30% more rigid than other aluminum alloy technologies of the same weight
• Avional aluminum alloy polycentric physioglide hinges for strength
• anatomically premolded frame to reduce torsional forces

• The mechanical movement of the physioglide hinge closely matches the physiological roll-glide-movement of the knee joint. The shifting of the inner and outer hinge plates (see diagram) lengthens the physioglide hinge at flexion and shortens it at extension. This effect reduces the "downward pressure" on the brace.

• The top section of the half-moon shaped condyle pad is positioned above the medial condyle of the femur and helps prevent the M.4OA from sliding.

• The M.4OA's soft-grip padding material offers excellent patient comfort and is "slide resistant" to help secure the correct fit of the brace.

• The numbered straps allow the patient to easily reproduce the correct fit of the brace.
