Osteoarthritis is a degenerative form of arthritis (painful swelling of the joints) that affects articular cartilage. Articular cartilage is the thin lining on the ends of bones that enables frictionless sliding during joint movement.
Osteoarthritis causes the thinning and destruction of articular cartilage, exposing the bone directly to the movement of the joint. Patients with osteoarthritis commonly experience a “grating sensation” as they move and their bones slide against each other.
Osteoarthritis commonly affects the joints of the knees, hips, and fingers. Common symptoms include pain and stiffness of the affected joint, loss of flexibility, and bone spurs.
