Definition

1. Noun:
   • A chronic degenerative joint disease: Osteoarthritis is a medical condition characterized by the gradual breakdown and eventual loss of the cartilage that cushions the ends of bones in a joint. It is the most common form of arthritis.

Usage

• Osteoarthritis is a non-inflammatory condition primarily affecting weight-bearing joints like the knees, hips, and spine, as well as the hands.
• It is typically associated with aging, wear and tear, and often develops after middle age.
• The term is used in medical and general contexts to describe this specific type of joint degeneration.

Examples

• Noun:
  • My grandmother suffers from osteoarthritis in her knees, which makes walking difficult.
  • The doctor explained that the pain was due to osteoarthritis, not rheumatoid arthritis.
  • Regular, low-impact exercise can help manage the symptoms of osteoarthritis.

Advanced Usage

• "Primary osteoarthritis": The most common form, with no identifiable underlying cause, generally related to aging.

Notes
