Joint pain in old age can be due to wear and tear of cartilage, inflammation, or conditions like osteoarthritis. As people age, the cartilage in joints breaks down, leaving bones to rub against each other. Inflammation can also play a role in joint pain in old age.
Cartilage cannot repair itself.
Chondromalacia can affect any joint, but the most common location is inside the knee. It usually begins as a small area of softened cartilage behind the kneecap (patella) that can be painful. Eventually, more of the cartilage softens, and the softened cartilage can crack or shred into a mass of fibers. In severe cases, the damaged cartilage can wear away completely, down to the undersurface of the kneecap. If this happens, the exposed kneecap's bony surface can grind painfully against other knee bones. Also, bits of cartilage can float inside the joint, further irritating the cells that line the joint. In response, these cells produce fluid inside the joint (called a joint effusion).
