Abstract：Objective Exploring the varying diagnostic benefits of CT and magnetic resonance imaging in ligament and tendon injuries around knee joint fractures is the objective. Methods Select 80 patients with knee joint fractures accompanied by peripheral ligament and tendon injuries as the research subjects.The patients were divided into three categories based on the type of examination：CT,MRI,and joint inspection.Subsequently,the exactness,sensitivity,and precision of each single examination was compared and evaluated. Results （1）48 suspected cases were diagnosed by the "gold standard" examination,and the diagnosis rate was 60.0%.There were 35 patients with positive CT examination,40 patients with positive MRI examination and 46 patients with positive combined examination.（2）In this study,the accuracy of CT is 65%,the accuracy of MRI is 77.5%,and the accuracy of combined examination is the highest,reaching 95%.The sensitivity of CT is 72.92%,that of MRI is 83.33%,and the sensitivity of combined examination is the highest,which is 95.83%.The specificity of CT is 53.13%,the specificity of MRI is 68.75%,and the specificity of combined examination is the highest,which is 93.75%.Compared with CT and MRI,the combined examination showed significant statistical differences（P<0.001）,in which the accuracy,sensitivity and specificity were 95.00%,95.83% and 93.75% respectively.Combined examination is superior to CT or MRI alone in diagnostic accuracy. Conclusion The combined examination of CT and MRI has high diagnostic efficiency in the diagnosis of ligament and tendon injuries around knee joint fractures,with accuracy,sensitivity and specificity of 95.00%,95.83% and 93.75% respectively,which is worthy of clinical promotion.
