Clinical Information
  • A disease that causes inflammation and pain in the joints.
  • A disorder characterized by inflammation involving a joint.
  • A joint is where two or more bones come together, like the knee, hip, elbow or shoulder. Joints can be damaged by many types of injuries or diseases. arthritis or simply years of use may cause a joint to wear away. This can cause pain, stiffness and swelling. Over time, a swollen joint can become severely damaged. Treatment of joint problems depends on the cause. If you have a sports injury, treatment often begins with the rice (rest, ice, compression and elevation) method to relieve pain, reduce swelling and speed healing. Other possible treatments include pain relievers, keeping the injured area from moving, rehabilitation, and sometimes surgery. For arthritis, injuries, or other diseases, you may need joint replacement surgery to remove the damaged joint and put in a new one. nih: national institute of arthritis and musculoskeletal and skin diseases
  • A noninflammatory degenerative joint disease occurring chiefly in older persons, characterised by degeneration of the articular cartilage, hypertrophy of bone at the margins and changes in the synovial membrane. It is accompanied by pain and stiffness, particularly after prolonged activity. (on-line medical dictionary)
  • A progressive, degenerative joint disease, the most common form of arthritis, especially in older persons. The disease is thought to result not from the aging process but from biochemical changes and biomechanical stresses affecting articular cartilage. In the foreign literature it is often called osteoarthrosis deformans.
  • An inflammatory process affecting a joint. Causes include infection, autoimmune processes, degenerative processes, and trauma. Signs and symptoms may include swelling around the affected joint and pain.
  • Any disorder of the joints.
  • Condition in which there is a deviation from or interruption of the normal structure or function of the joints.
  • If you feel pain and stiffness in your body or have trouble moving around, you might have arthritis. 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.one type of arthritis, osteoarthritis, is 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. infectious arthritis is an infection that has spread from another part of the body to the joint. nih: national institute of arthritis and musculoskeletal and skin diseases
  • Inflammation of the joints; tends to be chronic.
  • Noninflammatory degenerative joint disease occurring chiefly in older persons, characterized by degeneration of the articular cartilage, hypertrophy of bone at the margins, and changes in the synovial membrane, accompanied by pain and stiffness.
  • Osteoarthritis is the most common form of arthritis. It causes pain, swelling, and reduced motion in your joints. It can occur in any joint, but usually it affects your hands, knees, hips or spine.osteoarthritis breaks down the cartilage in your joints. Cartilage is the slippery tissue that covers the ends of bones in a joint. Healthy cartilage absorbs the shock of movement. When you lose cartilage, your bones rub together. Over time, this rubbing can permanently damage the joint. Risk factors for osteoarthritis include
    • being overweight
    • getting older
    • injuring a joint
    no single test can diagnose osteoarthritis. Most doctors use several methods, including medical history, a physical exam, x-rays, or lab tests.treatments include exercise, medicines, and sometimes surgery. nih: national institute of arthritis and musculoskeletal and skin diseases
