Osteoarthritis can range from mild to severe. The pain associated with osteoarthritis can be significant and it usually is made worse by movement. Osteoarthritis can be limited to one joint or start in one joint usually the knee, hip, hand, foot or spine or it can involve a number of joints. If the hand is affected, usually many joints of the fingers become arthritic. Osteoarthritis probably does not have a single cause, and, for most people, no cause can be identified. Age is a leading risk factor, because osteoarthritis usually occurs as people get older. However, research suggests that joints do not always deteriorate as people age.
In OA, this cartilage breaks down.OA usually occurs in the fingers and weight-bearing joints; these include, knees, feet, hips and back. Osteoarthritis is the result of changes in the cells of the cartilage resulting in a loss of elasticity. Over time this causes the cartilage to thin out and in some situation breakdown all together. This leaves the ends of the bone without its smooth covering, and the joint loses its easy mobility..
