Comparative Analysis of the Efficacy of MRI and DR in the Diagnosis of Acute Knee Joint Injury
Objective:To analyze and compare the efficacy of magnetic resonance imaging(MRI)and X-ray digital radiography(DR)in the diagnosis of acute knee joint injury.Methods:A retrospective analy-sis was conducted on the data of 80 patients(129 knees)with acute knee joint injury admitted to Meizhou Second Traditional Chinese Medicine Hospital from January 2021 to April 2023.Using the results of ar-throscopy as the gold standard,compare the diagnostic efficacy of MRI and DR in the diagnosis of acute knee injury,as well as their combination.Results:The accuracy of DR in diagnosing acute knee joint in-jury was 85.27％(110/129),with a Kappa value of 0.71;the accuracy of ligament injury was 82.95％(107/129),and the Kappa value was 0.64;the accuracy of bone damage was 87.60％(113/129),with a Kappa value of 0.74;the accuracy of MRI in diagnosing acute knee joint injury with meniscus injury was 93.80％(121/129),and the Kappa value was 0.88;the accuracy of ligament injury was 87.60％(113/129),with a Kappa value of 0.73;the accuracy of bone damage was 96.12％(124/129),with a Kappa value of 0.92;the accuracy of MRI combined with DR in diagnosing acute knee joint injury with meniscus injury was 95.35％(123/129),and the Kappa value was 0.91;The accuracy of ligament injury was 95.35％(123/129),and the Kappa value was 0.89;The accuracy of bone damage was 96.12％(124/129),with a Kappa value of 0.92.The accuracy of MRI examination and joint examination in diagnosing meniscus injury and bone injury was significantly higher than that of DR(P＜0.05),while the accuracy of joint examination in diag-nosing ligament injury was higher than that of MRI and DR individual examinations(P＜0.05).Conclusion:Both MRI and DR have high efficacy in the diagnosis of acute knee joint injury,and MRI has higher ad-vantages in the diagnosis of meniscus injury and bone injury.The combination of the two can effectively improve the accuracy of knee joint ligament injury.
