Much less common than for the knees, hips, hands or spine, osteoarthritis of the ankle or big toe are very often secondary to a known factor (repeated sprains, after-effects of a fracture, etc.).
Osteoarthritis of the big toe is most commonly due to injury, a walking problem or a particular shape of the foot.
Osteoarthritis of the ankle is quite rare. It is often due to old injuries or repeated ligament sprains. It may also appear on a joint affected by inflammatory arthritis such as rheumatoid arthritis.
