Background: Introduced in 2014, the diagnostic accuracy of the Lever Sign (LS) in detecting acute complete anterior cruciate ligament (ACL) lesions is not well documented. Purpose: To assess the diagnostic accuracy of the LS, Lachman’s Test (LT), and Drawer Test (DT) in the detection of acute ACL lesions, including a population with an intact ACL. Methods: We reviewed the records of 70 acute (< 72 hours postinjury) knee injuries. Deidentified records were collected from high school and collegiate athletic trainers using a standardized form. Statistical Analysis: The DT and LT were performed 69 times and the LS 42 times. A 2 x 2 contingency table including 95% confidence intervals (CI) were created. A receiver operating characteristic (ROC) curve was created and data from the knee inventory form were filtered for patient-perceived pain. Results: The LS yielded a sensitivity of .85 and specificity of .97. The LT and DT yielded a sensitivity of .75 and .60 and a specificity of .94 and .96. ROC curves demonstrated that the LS, LT and DT produced an area under the curve (AUC) of .88, .83, and .77. Last, the patient-perceived pain at a frequency of 40% when the LS was performed on an ACL lesion and a frequency of 13% when the test was performed and an ACL lesion was not present. No statistically significant differences were identified among the 3 tests. Conclusion: Although not statistically significant, the LS produced a better diagnostic accuracy than the LT and DT in the detection of acute complete ACL lesions. The LS had a decreased frequency of patient-perceived pain when performed, decreasing the chance of a false negative. We propose that clinicians can use the LS in the assessment of suspected ACL lesions.
