On the current research of osteoarthritis have around 12 journals, 10 conferences and 15 workshops are presently dedicated to osteoarthritis and around 400 articles are being published on the current trends in osteoarthritis. About 27 million people in America have osteoarthritis. Common risk factors include increasing age, obesity, previous joint injury, overuse of the joint, weak thigh muscles and genetics. Osteoarthritis (OA) is one of the most common forms of arthritis. It is a chronic condition in which the material that cushions the joints, called cartilage, breaks down. This causes the bones to rub against each other, causing stiffness, pain and loss of joint movement. The Osteoarthritis Research Society International (OARSI) is the premier international organization for scientists and health care professionals focused on the prevention and treatment of osteoarthritis through the promotion and presentation of research, education and the world-wide dissemination of new knowledge.
