Osteoarthritis occurs when the cartilage of a joint erodes (breaks down). Bones begin to rub against each other, causing pain and difficulty moving the joint. Osteoarthritis also can affect nearby bones, which can become enlarged in places. These enlargements are called bone spurs or osteophytes.
The most common complications of osteoarthritis (OA) are joint pain and stiffness, which can interfere with daily activities. Osteoarthritis can affect almost any joint, but is most typical in the joints that bear weight over the years, such as the knees, hips and lower back. In most cases, OA develops slowly over time, but it can worsen rapidly in severe cases.
