Damaged connective tissue in the joint is removed to allow new, healthy tissue to grow in its place. Sometimes the entire joint is replaced with an artificial one. If they are present, you have rheumatoid arthritis. Note that there is no real cure for rheumatoid arthritis, though symptoms can be alleviated in most individuals if treated aggressively. Treatment for kids is about the same as for adults, but emphasizing physical therapy and exercise.
Most kids can and do recover fully from juvenile rheumatoid arthritis.
Testing a fluid sample from the affected joint can determine whether you have infectious arthritis. Large intravenous doses of antibiotics and draining excess fluid from the joints is the common practice. Treating the primary illness is key as well. An X-ray will detect the presence of osteoarthritis. If you've had gastrointestinal bleeding or are over 65, consult with your doctor first.
