Frequently Asked Questions
What is a "Polycentric" joint?
Unlike a standard hinge, a polycentric joint has multiple rotation points. This allows the brace to mimic the natural, complex sliding-and-rolling motion of the human knee, preventing the brace from slipping and providing more accurate support during movement.
Is this brace suitable for hot weather?
Absolutely. The Airtex Pro line features 100% active breathability. The FlexEcoSense material and mesh fabric in the popliteal fossa (the back of the knee) are designed to maximize airflow and prevent moisture buildup.
Can I wear this on either leg?
Yes, this orthosis is bilateral, meaning it is anatomically designed to fit comfortably and provide equal stability on either the left or the right knee.
