Purpose
[edit | edit source]
To test the integrity of the anterior cruciate ligament (ACL)
Technique
[edit | edit source]
The patient is supine and the knee to be tested is flexed to approximately 90 degrees. The examiner then sits on the toes of the tested extremity to help stabilize it. The examiner grasps the proximal lower leg, approximately at the tibial plateau or joint line, and attempts to translate the lower leg anteriorly. The test is considered positive if there is a lack of end feel or excessive anterior translation.[1]

Evidence
[edit | edit source]
One source reports sensitivity and specificity as .41-.91 and .86-1.0 respectively, with a -LR of .09-.62 and a +LR of 5.4-8.2.[1] However, a recent meta-analysis reports the sensitivity and specificity as .18-.92 and .78-.98 respectively.[3] Scholten et al concluded that based on predictive value statistics, strong conclusions could not be made regarding whether the anterior drawer test was good to rule in or rule out the presence of an ACL tear.[3] Other recent research has identified the anterior drawer test as a more effective test to identify chronic conditions, with a sensitivity and specificity of .92 and .91.[4]
