The OPPO Closed Patella Knee Support provides support for weak or overstressed knees, and is helpful for post-operative knee problems, strains or arthritis. This support is designed with a neoprene rubber layer sandwiched between durable cotton and nylon laminates. This helps retain body heat and increase blood circulation which accelerates the bodyâ€™s natural healing process, relieving pain, swelling and stiffness and helping injuries to recover faster. It also reduces the risk of new or recurring injuries by creating greater flexibility in muscles, tendons and ligaments. It is designed to fit neatly and comfortably under clothing, and is easy to slip on or off.
