Osteoarthritis occurs throughout the world and in all
population groups. Osteoarthritis is equally common in men and women, but women
tend to develop symptoms earlier. It is estimated that 70% to 90% of people
older than age 75 are affected by osteoarthritis.1
They either have symptoms of osteoarthritis or have evidence of osteoarthritis
on an X-ray.
Osteoarthritis is the most common form of arthritis, and a major
reason people become disabled and dependent on others as they get
older.2
- In the general population, many people have
osteoarthritis that is evident on X-rays, although not all of these people have
symptoms. As seen on X-rays:
- 30% have osteoarthritis in the
hands.
- 21% have osteoarthritis in the feet.
- 3% have
osteoarthritis in the knees and hips.
- Of people older than 60, 17% of men and 30% of women have symptoms
of osteoarthritis.
- Of people older than 65:
- Almost all people have osteoarthritis in the
hands.
- 33% have osteoarthritis in the knee.
Although age itself is not a cause of osteoarthritis, the chances of
getting it increase significantly as people get older. Up to 33% of people in
the United States older than 18 report symptoms of arthritis or chronic joint
pain.3
