The ACL injury grades using the Lachmans test are as follows.Grade 1 means 3-5 mm of translation, grade 2 is 5-10 mm of translation and grade 3 is greater than 10 mm of translation.In addition to assessing the amount of translation of the tibia and the quality of the end point of the Lachman test, it is also important to examine the patellar and quadriceps tendons as the rupture of these tendons can be confused with a ACL rupture.Other tests for diagnosis of a ACL injury are the anterior drawer test which is not as reliable as the Lachman test. [13], An orthopedic device called the KT-1000 knee ligament arthrometer can be used in diagnosis to provide an objective measurement of anterior-posterior tibial translation.
