Pathological lesions of osteoarthritis, demonstrated by conventional radiography, can be assessed by scoring systems and/or measurement with a quite acceptable reproducibility. Scores are recommended for a rough staging of osteoarthritis and of bone changes. Measurement is recommended for assessment of joint space narrowing progression. A good assessment of progression implicates a perfect reproducibility of the radiographic image of the joint. Accuracy of standard radiograph is improved by some views such as the hip profile and the schuss view.
