Abstract:
Objective:To investigate the diagnostic value of MRI in the knee anterior cruciate ligament tear.Methods: retrospective analysis for treatment of 40 patients with anterior cruciate ligament tear by observation group, by analyzing the clinical data and image, and selected the same period for treatment of 20 cases of patients with knee joint other lesions but ACL normal MRI data comparison by Control group, The form characteristics of ACL and abnormal signal strength, whether there is a line or an ACL tear with signs were analyzed.Results:The MRI diagnosis of ACL tear completely is higher for the sensitivity and specificity (87.5%, 90%; Diagnosis of ACL partial tear, and arthroscopy and surgery results in 8 cases, the rest 4 cases of complete tear, 4 cases of false negative; ACL tear with signs including abnormal curvature of bone contusion, photo, or meniscus has obvious lateral collateral ligament damage, tibia forward, etc. ACL tear group and normal group average photo Angle, PCLS L/H mean significant difference.Conclusion: through analysis of MRI diagnosis torn ACL completeness, has high accuracy, but the part in the ACL tear or chronic tear diagnosis, accurate rate is relatively low.
