Abstract
Objective: To describe the characteristic figure and to assess the value of MRI in detemining anterior cruciate ligament (ACL) tear. Subject and method: 54 patients with injury knee treated at 103 Military Hospital and Vietduc Hospital from Jan. 2018 to Apr. 2019. The findings on MRI were compared with those on arthroscopy by Kappa. Compare result of ACL tear on MRI with those on arthroscopy by table 2 × 2. Result: Primary signs: Abnormal morphology of the anterior cruciate ligament 57.4%, nonvisualization of the ACL 37%, avulsion at the tibial attachment 5.6%. Secondary signs: Buckling of posterior cruciate ligament 29.6%, anterior tibial translocation 46.3%, uncovered posterior horn of the lateral meniscus 25.9%. MRI had sensitivity of 98.1% and specificity of 100% in diagnosing ACL tear. Good correlation between grade tear assessment on MRI and those on arthroscopy, K = 0.698. Conclusion: MR image is useful for determining anterior cruciate ligament tear.
Keywords: Anterior cruciate ligament, posterior cruciate ligament, MRI, arthroscopy.
