Osteoarthritis of the hip

Picture of a hip joint affected by osteoarthritis

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
