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.
Evidence
[edit | edit source]
Sensitivity and specificity has been reported as .41-.91 and .86-1.0 respectively, with a -LR of .09-.62 and a +LR of 5.4-8.2. More recent research has identified that the anterior drawer test is more effective at identifying chronic conditions, with a sensitivity and specificity of .92 and .91.
