In osteoarthritis, the cartilage that protects and cushions
the joints breaks down over time. As the cartilage wears down, the bone
surfaces rub against each other. This damages the tissue and bone, which then
causes pain. The joint space in this hip joint is narrowed due to cartilage
loss and bone spur formation.
Damaged cartilage and bone are removed from hip socket and femur
