Count on PRO to design a wraparound support that gives the compression and support of a traditional pull-on sleeve. The unique three pull adjustment system (U.S. Patent # 5,865,777) allows the user to independently adjust the fit at the thigh, knee and calf. The center tab enables the wearer to regulate pressure in the popliteal area no matter if they are sitting, standing or running. The moveable patella buttress attaches by means of hook and loop fasteners providing additional support to the patella if desired. Lateral and medial spiral stays provide additional support. Ideal for Chondromalacia, Patella Instabilities, Arthritis, Post Injury and Arthroscopic Rehabilitation. Available in black N2 material only. Standard size fits knee circumference of 12” to 18” and extra large fits 18” to 24”. Please visit our website at www.proorthopedic.com for size charts and measuring instructions.
