MRI has demonstrated high diagnostic value in the assessment of musculoskeletal disease. Pathological joint changes, especially in the osteochondral region, are an important orthopedic problem because the signs and symptoms are vague and unspecific. Therefore, in early disease their extent and severity are difficult to ascertain clinically. Early diagnosis and exact staging are recommended for sufficient therapeutic management. MR imaging has proved to be the method of choice in the evaluation of osteochondral lesions and helps to prevent late-stage disease and joint damage.
