Osteoarthritis, the most common form of arthritis, is the destruction of the articular cartilage, or protective covering of the bone, in a joint. The cartilage cushions the bones as they move to provide smooth motion of the bones. Cartilage can wear down over time causing the cartilage to become rough and the bones to begin to rub against each other.
Osteoarthritis can be the result of trauma or infection, but also can develop as a result of age, being overweight or performing repetitive actions. Women tend to be more prone to osteoarthritis.
