Posterior Drawer Test of the Knee
- Posterior Drawer Test of the Knee is used to test the integrity of the posterior cruciate ligament (PCL).
- 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 with the thumbs placed on the tibial tuberosity.
- Then the examiner attempts to translate the lower leg posteriorly.
- The Posterior Drawer Test is considered positive if there is a lack of end feel or excessive posterior translation.
- Sensitivity: 90 %
- Specificity: 99 %
