FIBERGLASS-MATRIX FRAME: The frame is designed to accommodate the dynamics of the leg musculature, allowing the muscles to flex and relax without interference. Not only does this design keep the frame properly positioned on the leg, it does so without constricting the muscles as they pump.
GLIDE HINGE: Our patented asymmetrical eight sphere, four bar hinge mechanism is the only hinge available that actually tracks the natural "rolling-gliding", dual center rotation motion of the knee joint.
ANTI ROTATION TETHER: The Anti-Rotation tether is the most effective defense against this type of lower leg rotation.
To ensure proper fit, circumference measurements should be taken on the skin with the leg straightened, using a soft tape measure. (If a soft tape measure is not available, a piece of string or yarn may be used, then measured against a hard tape measure.)
1. Locate the middle of the kneecap and measure around the leg.
2. Choose proper size from Circumference Chart below for the appropriate product.
