Get back to not thinking about your feet.
There are three types of arthritis that may affect your foot and ankle.
Osteoarthritis, also known as degenerative or "wear and tear" arthritis is a common problem for many people after they reach middle age. Over the years, the smooth, gliding surface covering the ends of bones (cartilage) becomes worn and frayed. This results in inflammation, swelling, and pain in the joint.
Osteoarthritis progresses slowly and the pain and stiffness it causes worsens over time.
Unlike osteoarthritis which follows a predictable pattern in certain joints, rheumatoid arthritis is a system-wide disease. It is an inflammatory disease where the patient's own immune system attacks and destroys cartilage.
Post-traumatic arthritis can develop after an injury to the foot or ankle. This type of arthritis is similar to osteoarthritis and may develop years after a fracture, severe sprain, or ligament injury.
