Kellgren-Lawrence grading system classifies radiographic severity of which condition?

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

Answer: (B)

The Kellgren-Lawrence grading system is used to classify how severe osteoarthritis looks on radiographs. It focuses on features such as osteophyte formation, joint space narrowing, subchondral sclerosis, and deformity of the bone ends. These radiographic signs increase with higher grades, from minimal or doubtful changes to definite osteophytes with narrowing and eventual deformity. This makes it specific to osteoarthritis. It isn’t used for osteoporosis (bone density loss), gout (uric acid crystal deposition and erosions), or rheumatoid arthritis (inflammatory erosions and joint damage tracked with other scoring systems).
