Diagnostic Accuracy of Anterior Draw Test and MRI for Assessing ACL Tears of the Knee

ABSTRACT: Cruciate ligaments are most commonly effected by any hard force applied on them. In cruciate ligaments anterior cruciate ligaments are mostly effected. As a result of which severe pain occurs in the joint. OBJECTIVES: To determine the diagnostic accuracy of anterior draw test and MRI for assessing ACL lesions of the knee. METHODS: 145 Patients including both genders were selected from AL-Razi Health care, MM Alam road Lahore, during 9 months from June 2017 to February 2018. The inclusion criteria was patients with knee injuries that have undergone MRI and ADT were included. Sensitivity, specificity, positive predictive value and negative predictive value tests was used for diagnostic accuracy of MRI and clinical findings separately (as per operational definition). P-value < 0.05 will be considered significant. The data were analyzed on SPSS version 24.0. RESULTS: The mean age of patient was 37.06±16.796, 92(63.4%) were male and 53(36.6%) female. There were 68(46.9%) patients with positive anterior drawer test and 77(53.1%) negative anterior drawer test cases. There were 129(89%) patients with positive magnetic resonance findings and 16(11%) with negative magnetic resonance findings. Out of 145 patients 62(42.8%) were true positive for ADT and MRI,6(46.9%) were false positive for both ADT and MRI ,67(46.2%) were false negative for both ADT and MRI and 10(6.9%) true negative were for both MRI and ADT. CONCLUSIONS: It was concluded that magnetic resonance imaging is more significant and accurate as compare to anterior draw test.
