## 해설

Osteoarthritis is a degenerative joint condition where the protective cartilage that cushions the ends of bones wears down over time. It's the most common form of arthritis, typically affecting weight-bearing joints. The condition leads to pain, stiffness, and reduced joint mobility. Risk factors include age, obesity, joint injuries, and genetic predisposition.
