A risk factor is something that raises the chances of getting a health problem. A person can get OA with or without the ones listed below. The chances of getting OA are greater in people who have many.

OA is more common in older adults. It is also more common in women. Other things that can raise the risk are:

  • Obesity, which causes extra strain on the joints
  • Jobs or sports with lifting, squatting, kneeling, or repeated joint use
  • Having people in your family with OA
  • Weak muscles or tendons that cannot support joints
  • Prior injury to the joint
  • History of joint infection or disease
  • Structural problems—may cause balance or alignment problems that put stress on joints
