Topic Overview

Osteoarthritis is a common
cartilage condition and a major cause of pain and
disability in older adults. Primary osteoarthritis
results from changes over time often linked to things such as age, obesity, and
a family history of osteoarthritis. Secondary
osteoarthritis is caused by other conditions that damage cartilage.
