Abstract
Plain film radiography still remains the “gold” standard in the assessment of knee osteoarthritis. It is a two-dimensional projection of three-dimensional joint structures. Radiographic changes include joint space narrowing, formation of osteophytes, subchondral osteosclerosis and cysts, deformity of the bone contour to complete ankylosis. These changes occur in various stages of development of osteoarthritis and are reflected in semiquantitative assessment scales.
One of the most commonly used scale is the one created by Kellgren and Lawrence back in 1957, underwent many modifications over time. An atlas from the Osteoarthritis Research Society International (OARSI) offers another approach for semiquantitative evaluation. Measuring the distance between the femoral and tibial projected boundaries is the most common quantitative method for assessing knee osteoarthritis.
