Arthritis: An Overview
Arthritis is inflammation of one or more of your joints that causes pain and stiffness. While arthritis is mainly an adult disease, some forms affect children.
There are many types of arthritis. Some of these include osteoarthritis, rheumatoid arthritis, post-traumatic arthritis, septic arthritis, and psoriatic arthritis.
While each of these conditions have different causes, the symptoms and treatment are often the same. Pain, swelling, and stiffness are the primary symptoms of arthritis. Any joint in the body may be affected by the disease, but it is particularly common in weight-bearing joints such as the knee, hip, and spine.
Although there is no cure for arthritis, there are many treatment options available to help manage pain and keep people staying active.
Anatomy
Arthritis is a disease of the joint. A joint is where the ends of two or more bones meet. The knee joint, for example, is formed between the bones of the lower leg (the tibia and the fibula) and the thighbone (the femur). The hip joint is where the top of the thighbone (femoral head) meets a concave portion of the pelvis (the acetabulum).
Cartilage. A smooth tissue of cartilage covers the ends of bones in a joint. Cartilage cushions the bone and allows the joint to move easily without the friction that would come with bone-on-bone contact.
Synovium. A joint is enclosed by a fibrous envelope, called the synovium, which produces a fluid that also helps to reduce friction and wear in a joint.
Muscles, tendons, and ligaments. Ligaments connect the bones and keep the joint stable. Muscles and tendons power the joint and enable it to move.
