Anterior Drawer Test of the Knee
Anterior Drawer Test of the Knee is used to determine the integrity of the Anterior Cruciate Ligament (ACL) – full or partial tear.
- The knee is flexed between 60 and 90 degrees with the foot resting on the exam table.
- The examiner puts both hands behind the tibia and attempts to displace the tibia anteriorly while the foot remains resting on the table.
- Increased tibial displacement with the foot in neutral indicates a positive Anterior Test Knee which is graded by severity:
- Grade 1 = 5 mm
- Grade II = 5-10mm
- Grade III = > 10 mm.
- Sensitivity: 18- 92 %
- Specificity: 78-98 %
