Osteoarthritis is the most common joint disease affecting millions of people throughout the world. Osteoarthritis can affect any joint but it most commonly affects the weight bearing joints- hands, knees, hips, spine. In every joint there is a protective cartilage which prevents the two bones in the joints from coming in contact with each other. In osteoarthritis the protective cartilage wears down with age and exposes the bones in joint to each other causing rubbing. This rubbing causes pain and stiffness.
Osteoarthritis usually occurs in older age but can be seen in adults also. As there is degeneration in the bone, the disease is also known as degenerative joint disease and is a leading cause of disability is older people.
Osteoarthritis is a degenerative disease and in advanced cases causes severe disability. People are not able to perform the daily chores and are sometimes confined to bed only.
