Radiographic assessment of hip and knee osteoarthritis. Recommendations: recommended guidelines

Pathological lesions of osteoarthritis, demonstrated by conventional radiog raphy, can be assessed by scoring systems and/or measurement with a quite a cceptable reproducibility. Scores are recommended for a rough staging of os teoarthritis and of bone changes. Measurement is recommended for assessment of joint space narrowing progression. A good assessment of progression imp licates a perfect reproducibility of the radiographic image of the joint. A ccuracy of standard radiograph is improved by some views such as the hip pr ofile and the schuss view.
