Thirty-two million Americans have osteoarthritis, deterioration of joint cartilage and the attached bone. Many also have post-traumatic osteoarthritis, PTOA, as a result of an injury, like the more than 3 million veterans who suffer from it. There is no treatment for PTOA other than over-the-counter medications. Yet, researchers have developed a revolutionary gel, which can potentially be delivered by injection directly to the diseased joints to reduce inflammation and induce cartilage regeneration.
