This is going to be the anterior drawer test to test for ACL tears.
The anterior drawer test has a sensitivity of 92%
and a specificity of 91%,
according to a meta-analysis done by Benjaminse et al. in the year 2006.
These values are reported for a chronic situation,
while the test performs way poorer in an acute situation.
For the anterior drawer test it is first recommended to exclude a PCL injury in order to avoid false positive results,
so click on the video right here to watch the posterior sag sign,
or click on the video right here to watch our video on the posterior drawer test.
To perform the anterior drawer test bring your patient's hip to 45 and your patients knee to 90 degrees of flexion.
You can fixate this position by gently sitting on the foot of your patient.
Then palpate the joint line with your thumbs,
and try to move the tibia anteriorly in an explosive movement.
This test is positive if the tibia
translates anteriorly more than six millimeters or if you experience a soft and mushy end feel.
This was our video on the anterior drawer test.
