How does osteoarthritis affect the knee?

• A. It creates new bone growth
• B. It leads to degeneration of cartilage
• C. It inflates synovial fluid levels
• D. It strengthens ligaments

Answer: (B)

Osteoarthritis is a degenerative joint condition characterized primarily by the deterioration of cartilage, which is the smooth tissue that covers the ends of bones in a joint. In the knee, this degeneration can lead to pain, swelling, and reduced mobility as the protective cartilage wears away, causing the bones to rub against each other. This process contributes to inflammation and stiffness, significantly impacting a person's quality of life. The correct understanding of osteoarthritis in the context of the knee highlights the critical role that cartilage plays in joint health. As the cartilage degenerates, it affects not only the pain levels but also the overall function of the knee joint, leading to further complications, such as bone spurs and changes in the bone structure. Therefore, recognizing the primary effect of osteoarthritis as the degeneration of cartilage is essential for both diagnosing and managing the condition effectively.
