Knee - Anterior Drawer Test

The Anterior Drawer Test for the knee is used to examine the integrity of the anterior cruciate ligament. The patient is placed supine on the table with the knee in 90 degrees of flexion and the hip flexed approximately 45 degrees. The examiner places her hands around the proximal tibial with her thumbs crossing the anterior joint line. The patient's foot is anchored in a neutral position by the examiner's thigh. The examiner tells the patient to relax her hamstrings. This suggestion is enhanced through a light tapping with the examiners fingers on the tendons of the hamstrings just behind the knee. Once the patient is relaxed the examiner attempts to pull the tibia anteriorly. Instability is determined by examining bilaterally and comparing the amount of excursion present.

Hey there, what happens if there is bilateral ACL damage, isn't there a numerical amount of translation that should be seen? ie over 6mm of translation is pathological.
