Many forms of arthritis and related conditions that affect the joint, muscles and/or bones can cause hip problems like pain, stiffness and swelling.

Here are some possible disease-related hip problems.

Osteoarthritis (OA). The most common form of hip arthritis, osteoarthritis is a chronic condition characterized by the breakdown of the cartilage that cushions the ends of the bones where they meet to form joints. In hip osteoarthritis, the cartilage that lines the acetabulum and/or covers the surface of the femoral head breaks down causing the bones to rub against each other. This may result in pain, stiffness, the loss of movement and the formation of bony overgrowths called spurs. Pain from hip osteoarthritis is often felt in the groin area and front of the thigh. Stiffness may be worst after periods of inactivity.

Rheumatoid arthritis (RA). Rheumatoid arthritis is a chronic inflammatory disease of the joints that occurs when body’s immune system – which normally protects us from infection – mistakenly attacks the synovium, the thin membrane that lines the joints. Symptoms of hip rheumatoid arthritis include pain, redness, swelling and warmth of the affected hip joints. Unchecked, inflammation can lead to hip joint damage loss of function and disability. In addition to the hips, rheumatoid arthritis commonly affects the knees, hands, wrists, feet, elbows and ankles.
