What is hip arthritis?

A healthy hip joint is a well-defined ball-and-socket joint with a space between the two bones at the point where the head of the femur moves freely inside the acetabulum (the cup-shaped socket in the hip bone) under normal circumstances; in an arthritic hip, the bones of the joint are not clearly defined, and in fact, because the loss of cartilage is extensive, the head of the femur is jams into or grinds against the acetabulum. This leads to a painful joint with limited mobility.
