How does osteoarthritis affect articular cartilage?

Aging decreases the ability of chondrocytes to maintain and restore articular cartilage and thereby increases the risk of degeneration of the articular cartilage surface. Progressive degeneration of articular cartilage leads to joint pain and dysfunction that is clinically identified as osteoarthritis.

What happens to articular cartilage in osteoarthritis?

Osteoarthritis—the most common type of arthritis—is a result of degenerated articular cartilage, causing pain, swelling, and reduced motion. While it can occur in any joint, one in two adults will develop symptoms of knee osteoarthritis during their lives, according to The Arthritis Foundation.
