This is a type of arthritis that can affect people of all ages. It’s not the same as the most common form of arthritis, called “osteoarthritis.” That type commonly comes from wear and tear. Inflammatory arthritis can develop without any wear and tear at all.
There are a few kinds of inflammatory arthritis. We don’t always understand what causes them, but they are linked to problems with your immune system. Your body begins to attack your healthy tissues. In the hip joint, this can cause the breakdown of cartilage. That’s the tough, smooth tissue that lines the ends of your bones. When it breaks down, your bones begin to rub directly against each other.
