Osteoarthritis is a condition in which the cartilage that protects and cushions joints breaks down over time. Eventually, the bones, formerly separated by cartilage, rub against each other. This results in damage to the tissue and underlying bone, causing the painful joint symptoms of osteoarthritis. The joint space in this hip joint is narrowed due to cartilage loss and bone spur formation.
