What is Kellgren-Lawrence grade 1 characterized by?

• A. Definite joint space narrowing
• B. No features of OA
• C. Large osteophytes
• D. Doubtful narrowing of joint space and possible osteophytic lipping

Answer: (D)

Kellgren-Lawrence grading is a radiographic way to describe how advanced osteoarthritis is on X-rays by looking for osteophytes, joint space changes, sclerosis, and deformity. In this grade, changes are minimal and may be ambiguous on the image. You can see small osteophytes (bone spurs) and only a doubtful or questionable narrowing of the joint space, with no definite loss of space or deformity. This distinguishes it from later grades, where osteophytes become definite and joint space narrowing is clear, often with sclerosis or bone deformity. So, a description of doubtful joint space narrowing with possible osteophytic lipping is the classic finding for this early stage.
