As two of the main weight-bearing joints in our body, our hips are subjected to a lot of wear and tear, which can lead to hip osteoarthritis.

We’ve added a new video to our Arthritis-health Video Library that illustrates how hip osteoarthritis develops and causes symptoms.
When the cartilage in the hip joint degenerates, this is known as hip osteoarthritis. It can lead to pain, inflammation, and decreased range of motion in the hip joint.
The hip is a large joint that’s shaped like a ball and socket and bears much of the body’s weight. The hip makes it possible to walk, run, and sit.
When hip osteoarthritis occurs, the cartilage that lines the socket, or acetabulum, and the ball, or femoral head, becomes inflamed.
This inflamed cartilage starts to wear away over time, causing the space between the bones to narrow. Joint damage may trigger new cartilage growth, but this new cartilage can be bumpy and irregular, only making the joint friction worse.
Eventually, the cartilage can wear away completely, causing the bones to be in direct contact with each other. This may cause bone spurs, or osteophytes, to form.
A sign of hip osteoarthritis may be a grating sensation when walking as the bones in the joint grind together.
The pain caused by hip osteoarthritis tends to be dull and be felt in the groin or down the front of the thigh.
It may also be felt in the lower back or buttocks. The pain may be constant or it may come and go.
In addition to the dull pain, patients may experience briefs periods of sharp, stabbing pain. They may also experience more limited range of motion as hip osteoarthritis progresses.
