The Neo G Kids Open Knee Support is specifically designed for the younger wearer and offers dynamic support and adjustable compression to the knee complex without restricting movement. The open patella design with stitched buttress helps with patellar tracking whilst providing added support and helping with overall stability by eliminating glide and twisting at the knee. Weight bearing pressure during movement is more evenly distributed over the joint helping with arthritic and meniscus pain. The durable, heat therapeutic neoprene helps with juvenile arthritis, chronic aches and stiffness. Fits up to 16inches / 40cm. Measure thigh circumference 3 Inches above knee for maximum size.
