+ve Lever Sign for ACL Tears
There is new emerging test for detecting an ACL rupture called the Lelli’s test. The test is considered positive if there is a +ve Lever Sign. The Lever sign has been shown to have excellent sensitivity and specificity for partial and full ACL tears and seems to be a better test than the Lachman, anterior drawer and the pivot shift tests.
I find that the Lachman is a good test if you have big hands and a small patient …it is a difficult test if you have small hands and a big patient. The good thing about the Lever Sign is that, with practice, it is a relatively easy test to perform irrespective of the size of your hands!
