Osteoarthritis (OA) is the most common form of arthritis and a major cause of joint pain and disability. OA is a degenerative disease affecting the cartilage and bone surfaces of a joint. With age, injury, or just wear-and-tear, joint cartilage will become thinner, allowing more pressure between bones. This causes pain, which could stop you from doing the things you enjoy most. In the early stages of OA pain, a knee brace has been found to be very successful in pain management and improved mobility. Having your bracing needs assessed and fit by a certified orthotist will ensure your best chance of success. B.D. Mitchell Posthetics & Orthotics, MitchellPAndO.com
