What is Kellgren-Lawrence grade 3 characterized by?

Explanation:
Kellgren-Lawrence grading uses X-ray features to stage osteoarthritis. Grade 3 reflects a moderate level of disease, with multiple osteophytes visible at the joint margins, a definite narrowing of the joint space from cartilage loss, plus some sclerosis of the subchondral bone and possible deformity of the bone ends. This combination shows progression beyond early OA but is not the most severe form, which would show large osteophytes, severe joint space loss, and marked deformity.
