Objective To study the diagnostic value of MRI on cartilage injury of knee joint. Methods The MRI data of 123 patients with cartilage injury of knee joint were analyzed respectively and were compared with results of arthroscope or operation. Results The total cartilage injury of knee joint presented with 99.15％ sensitivity,98.35％ specificity and 98.67％ accuracy, 99.44% negative predictive value, stage I～Ⅳ of positive predictive value was 82.35％、87.7％、94.4％、100％.The MRI result was similar to the arthroscope result（Kappa=0.949 p=0.000). Conclusions MRI demonstrated the location, range and injury degree of the cartilage injury exactly, which may be the best examination for cartilage injury.
