Arthritis


Arthritis literally means joint inflammation but is often used to indicate a group of more than 100 rheumatic diseases. These diseases can affect not only the joints but also muscles, tendons, and ligaments as well as the skin and certain internal organs.

Osteoarthritis

  • Osteoarthritis is the most common form of arthritis.
  • It affects 3,000,000 (1 in 10) Canadians.
  • It affects men and women in equal numbers.
  • Most people develop osteoarthritis after the age of 45, but it can occur at any age.

Osteoarthritis is caused by the breakdown of cartilage.  Cartilage is the tough elastic material that covers and protects the ends of bones. Cartilage acts as a shock absorber when you put weight on the joint. Bits of cartilage may break off and cause pain and swelling in the joint between bones.  This pain and swelling is called inflammation.

Over time the cartilage may wear away entirely, and the bones will rub together.

Osteoarthritis can affect any joint but usually affects hips, knees, hands and spine.

Symptoms of OA usually come on slowly, and involve the area around the joints. If you have joint pain, stiffness or swelling for more than two weeks visit your family doctor.
