Frequently Asked Questions

How do I measure for the correct size?
Measure around the center of your kneecap (directly over the patella) with your leg slightly bent. This Large/X-Large size fits a knee circumference of 16 to 19 inches. If your measurement falls at the top of a size range, size up for a more comfortable fit. Do not measure the thigh or calf — the knee circumference measurement is the correct reference point for this support.

What is an open patella design?
An open patella design has a cutout over the kneecap, leaving it exposed rather than covered. This allows the patella to move naturally during flexion and extension without being compressed by the brace material, and helps guide the kneecap into proper alignment during movement.

Can I wear this support during exercise or sports?
Yes. The two adjustable straps and hook-receptive neoprene are designed to stay secure during movement, making this support suitable for low to moderate activity including walking, light exercise, and daily tasks. For high-impact sports or activities requiring significant lateral stability, a more rigid hinged knee brace may be more appropriate.

Can I wear this over clothing?
This support is designed to be worn directly against the skin for best compression and fit. Wearing it over thin clothing is possible but may reduce the effectiveness of the neoprene compression and cause the support to shift during use.
