The Kellgren-Lawrence grading system is used to classify radiographic severity of which condition?

• A. Osteoarthritis
• B. Osteoporosis
• C. Gout
• D. Rheumatoid arthritis

Answer: (A)

The main idea here is identifying which condition a specific radiographic grading system is designed to assess. The Kellgren-Lawrence grading system is used to classify the radiographic severity of osteoarthritis. It evaluates signs visible on X-ray, such as osteophyte formation, joint space narrowing, subchondral sclerosis, and deformity of the bone ends. Grades range from minimal changes to severe joint degeneration, helping quantify how advanced the osteoarthritis is and guiding treatment decisions. This system is not used for osteoporosis (bone density loss), gout (urate crystal deposits and associated features), or rheumatoid arthritis (autoimmune inflammatory arthritis with erosions). Those conditions have different imaging findings and classification schemes.
