Diagnostic Accuracy of Anterior Drawer Test in Detection of Anterior Cruciate Ligament Tear Using Magnetic Resonance Imaging as Gold Standard.
J Surg Pak Jan ;20(4):119-22.

Objective: To determine the diagnostic accuracy of anterior Drawer test in detection of anterior cruciate ligament (ACL) tear, using MRI as gold standard. Study design: Cross sectional study. Place & Duration of study: Department of Orthopaedics and Trauma, Khyber Teaching Hospital Peshawar, from March 2013 to September 2013. Methodology: Patients presenting with post-traumatic knee pain and instability, were subjected to anterior Drawer test and then MRI of the involved knee was performed to match the findings of the two. The data was analyzed with SPSS version 10. Sensitivity, specificity, positive predictive value and negative predictive value were determined by taking MRI as gold standard. Results: A total of 115 patients were enrolled. There were 96 (83.48%) males and 19 (16.52%) females. On anterior Drawer test, true positive and true negative patients for ACL tear were 64 (55.65%) and 42 (36.52%) respectively while false positive and false negative patients for ACL tear were 3 (2.61%) and 6 (5.22%) respectively. The sensitivity and specificity of anterior Drawer test were 91.43% and 93.33% respectively while positive and negative predictive values were 95.52% and 87.50% respectively. The diagnostic accuracy was 92.20%. Conclusions: Anterior Drawer test has better specificity than sensitivity and high positive predictive value. It is more accurate in ruling out an anterior cruciate ligament injury.
