Objective:To explore the efficacy of CT and MRI in the grading of knee cartilage injury.Methods:A total of 80 patients with knee joint cartilage injury admitted to our hospital from January 2021 to January 2023 were retrospectively selected as the study objects.CT,MRI and arthroscopy were performed on all patients,and the grading diagnostic efficacy of both were evaluated according to the results of arthroscopy.The diagnostic value of CT and MRI in the classification of knee cartilage injury was compared.Results:The results of CT diagnosis were 28 cases of grade Ⅰ,34 cases of grade Ⅱ and 18 cases of grade Ⅲ and above.The grading results of MRI diagnosis were 31 cases of grade Ⅰ,29 cases of grade Ⅱ,and 20 cases of grade Ⅲ and above.Compared with the results of arthroscopy,the accuracy of CT grading was 81.25%(65/80)and that of MRI grading was 95.00%(76/80).The accuracy and total accuracy of grade Ⅰ diagnosis in patients with knee cartilage injury were compared between CT and MRI,and the difference was statistically significant(P＜0.05).Conclusion:Both CT and MRI can be used to grade knee cartilage injury,but MRI has higher diagnostic accuracy than CT and has higher diagnostic efficiency.
