Foot and Ankle Osteoarthritis

What Is Osteoarthritis?

Osteoarthritis, or “wear-and-tear” arthritis, is the most common type of arthritis. Also known as degenerative joint disease or age-related arthritis, osteoarthritis is more likely to develop as people age. Inflammation and injury to the joint cause a breaking down of cartilage tissues, resulting in pain, swelling, and deformity. The changes in osteoarthritis usually occur slowly over many years, though there are occasional exceptions.

How Does Osteoarthritis Affect the Foot and Ankle?

Each foot has 28 bones and more than 30 joints. The following are the most common foot joints affected by osteoarthritis:

  • The three joints of the foot that involve the heel bone, the inner mid-foot bone, and the outer mid-foot bone
  • The joint of the big toe and foot bone
  • The joint where the ankle and shinbone meet
