This is to avoid action by secondary stabilizers and also that it is not posteriorly subluxated prior to initiation of the physical test (as occurs in a PCL-deficient knee). [5], The test is considered positive if there is excessive anterior translation of the proximal tibia greater than the uninjured side and also a lack of a firm endpoint. It is important to evaluate and consider other knee structures that often sustain an injury in conjunction with an ACL injury, as isolated ACL tears reportedly occur less than 10% of the time in acute knee injuries. With a ACL rupture,the ACL will be lax and the examination will feel softer with no end point.The tibia can be pulled forward more than normal.Be aware that a PCL tear can cause posterior subluxation of the tibia and give rise to a false positive Lachmans test. Mild (grade I) is 0 to 5 mm, moderate is 6 to 10 mm (grade II), and severe is 11 to 15 mm (grade III) of anterior tibial translation compared to the uninjured side. Edit.
