Osteoarthritis is a chronic joint disorder which leads, over time, to the destruction of the cartilage. The joints are subjected to straining and significant compression in the course of one's life and this degenerative process increases with age, generally affecting people between 40 and 50 years of age. Osteoarthritis attacks and destroys the cartilage without swelling or infection, unlike arthritis, then creates a bony mass. It appears as chronic pain, a functional helplessness (diminution of mobility linked to pain), and stiffness. The joints which are most affected are the hips, knees, and vertebra.
