Polycentric Hinges:

• What they are: These are hinges with two moving arms that pivot around a central axis, creating a "moving center of rotation."

• Why it matters: The human knee doesn't just bend like a simple door hinge; it has a slight gliding and rotating motion as it flexes. Polycentric hinges replicate this motion more accurately, providing superior support and comfort during movement.

Rigorous Support & Stability:

• This brace is ideal for post-injury or post-surgical recovery where the knee ligaments (like ACL, PCL, MCL, LCL) need protection.

• It helps prevent harmful lateral (side-to-side) movements and hyperextension while allowing controlled, natural flexion and extension.

Adjustability:

• The hinges often have adjustable settings to limit the range of motion (ROM). A physiotherapist or doctor can set "stops" to prevent the knee from bending or straightening beyond a certain point, which is crucial for rehabilitation protocols.

Construction & Comfort:

• Material: Typically made from a breathable, elastic neoprene or similar material that provides compression, retains therapeutic warmth, and improves proprioception (your brain's sense of where your knee is in space).

• Support: It usually features reinforced spiral steel or aluminum stays on the sides for added rigidity.

• Straps: Comes with adjustable straps (often a supra-patellar strap above the kneecap and an infra-patellar strap below) to ensure a secure, customized fit and to prevent the brace from slipping down
