Osteoarthritis is the most common form of arthritis that affects the knee joint. Signs of osteoarthritis usually include chronic aches and pains as well as swelling and heat in and around the knee area. Although osteoarthritis is usually a result of the aging process, other factors increase the risk of developing osteoarthritis. These include:
  • Weight - Extra pounds put added stress on your knees. Controlling your weight can help relieve some of the pain associated with arthritis, and also can help you avoid getting arthritis
  • Activity - Overusing your knees can increase your risk of osteoarthritis. Continuous stress on the knee can wear down the cartilage cushion of the joint
  • Genetics - Osteoarthritis may have a genetic component
  • Altered Body Structure - Knees that are not aligned properly due to joint deformity or a difference in leg length result in increased joint stress and premature arthritis
  • Prior Injury - Knee injuries that damage the cartilage can result in premature arthritis
By strengthening the muscles that surround the knee joint the pain of osteoarthritis can be reduced. When the disease progresses, eventually a joint replacement will be required to increase movement and decrease pain.
