anterior drawer test

Quick Reference

A clinical test commonly used to determine ligamentous laxity in a sprained ankle or knee. When examining the ankle, the tibia and fibula are stabilized with one hand while the other hand, holding the foot in 20° plantar flexion, applies a posterior to anterior force in an attempt to move the talus forward in the ankle mortice. The amount of movement reflects the degree of injury to the ligaments. A similar procedure is used to assess the degree of instability of the tibia on the femur associated with a knee injury. The test is performed at 90° knee flexion with gentle pressure behind the tibial plateau to draw the tibia forward on the femur.
