Arthrosis of the knee usually requiring knee replacement is called?

• A. Bursitis
• B. Osgood-Schlatter disease
• C. Gonarthrosis
• D. Chondromalacia

Answer: (C)

Gonarthrosis is the degenerative arthritis of the knee, i.e., osteoarthritis of the knee. It involves wear and tear of the joint cartilage, narrowing of the joint space, and changes in the bones, which over time can cause chronic pain, stiffness, and reduced function. When the disease becomes severe and other treatments don’t relieve symptoms, knee replacement is often considered to restore function and alleviate pain.

Bursitis would present as swelling and tenderness from inflamed knee bursa rather than a primary degenerative joint issue. Osgood-Schlatter disease is an overuse injury at the tibial tubercle typically seen in adolescents. Chondromalacia refers to cartilage softening under the kneecap and causes anterior knee pain, but the term used for long-standing, joint-wide degenerative knee disease that may require replacement is gonarthrosis.
