The human body has more than 200 bones and more than 200 joints that connect the bones.
The most common joint problems come from arthritis and injuries. Joint damage can happen to anyone at any age.
Arthritis
If you feel pain and stiffness in your body or have trouble moving around, you might have arthritis.
- Arthritis literally means joint inflammation.
- Although joint inflammation describes a symptom or sign rather than a specific diagnosis, the term "arthritis" often refers to any disorder affecting the joints. These disorders fall within the broader category known as rheumatic diseases, of which there are more than 100 kinds, and are characterized by inflammation as well as loss of function of one or more connecting or supporting structures of the body.
- Most kinds of arthritis cause pain and swelling in your joints. Joints are places where two bones meet, such as your elbow or knee. Over time, a swollen joint can become severely damaged.
- Some kinds of arthritis can also cause problems in your organs, such as your eyes or skin.
More than 46 million people in the United States have arthritis or other rheumatic conditions. By the year 2020, this number is expected to reach 60 million. These diseases more frequently limit activity than do heart disease, cancer, or diabetes.
Symptoms of Rheumatic Disease or Arthritis
The symptoms of rheumatic disease or arthritis can vary. If you have a sports-related injury, get prompt medical attention to determine the severity. Symptoms of distress include:
- Swelling, warmth, or redness in the joint
- Recurring or constant joint pain or tenderness
- Joint stiffness or difficulty in using or moving the joint after a period of movement or activity
- A crunching feeling or the sound of bone rubbing on bone
Also called: Degenerative joint disease, OA, Osteoarthrosis
The most common form of arthritis is osteoarthritis, often related to aging or to an injury.
Other types occur when your immune system, which normally protects your body from infection, attacks your body's own tissues. Rheumatoid arthritis is the most common form of this kind of arthritis. Juvenile rheumatoid arthritis is a form of the disease that happens in children.
In osteoarthritis, the surface layer of cartilage (the hard but slippery tissue that covers the ends of bones) breaks down and wears away, causing pain, swelling, and loss of joint motion. Healthy cartilage absorbs the shock of movement. When you lose cartilage, your bones rub together. Over time, this rubbing can permanently damage the joint. It can occur in any joint, but usually it affects your hands, knees, hips or spine.
About 435,000 Americans have a hip or knee replaced each year. Because of its structure and weight-bearing capacity, the knee is the most commonly injured joint. In the case of hip joint damage, osteoarthritis is the most common cause.
Young adults who have had a previous joint injury are more likely to develop osteoarthritis. Researchers are looking for ways to prevent cartilage breakdown after injury.
Factors that may cause osteoarthritis include
- Being overweight
- Getting older
- Injuring a joint
Therapies that manage osteoarthritis pain and improve function include
- Exercise
- Weight control
- Rest
- Pain relief medication
- Alternative therapies
- Surgery
