what is


OA is a type of arthritis that develops in the joints, the areas in the body where the bones are linked together. OA often involves the hips, knees, neck, lower back, or small joints of the hands.

OA affects joints that are injured by repeated overuse. OA can occur after frequently performing a particular task or sport, or from carrying around excess body weight. Other risk factors include age and family history.

Symptoms of OA include:

  • Pain that worsens following exercise or rest
  • Development of bony spurs
  • Joint swelling
  • Reduced join flexibility
  • Grating sensation

What is the difference between OA and rheumatoid arthritis (RA)?

Arthritis is a general term for conditions that affect the joints and the tissues that surround them.

The two most common types are OA and RA. With OA, damage is caused by overuse of joints or excessive weight (OA is often called the “wear and tear” disease).

RA is an autoimmune inflammatory disease, in which the body attacks its own healthy tissue. As opposed to rheumatoid arthritis, your risk of developing OA increases as you age.

What leads to OA knee pain?

OA knee pain is caused by changes in synovial fluid and joint structures

A healthy knee contains synovial fluid, a viscous liquid that is responsible for lubricating the joint and absorbing shocks. Hyaluronic acid is a major component of normal synovial fluid and contributes to the fluid’s viscoelastic properties.

Changes in the synovial fluid and degeneration of joint structures may lead to OA knee pain.
