Anterior Drawer Test

This test is generally not useful for detecting injury in the acute situation (Fig. 2.10). The drawer becomes positive in the chronic case with capsular laxity. Do not confuse the anterior motion with the knee that is posteriorly subluxed and the anterior motion of pulling the knee to the neutral position. Always check for the tibial step. Examining the knee at 70° reminds you to test for the tibial stepoff. If you routinely do this, you will not miss a PCL injury.

Figure 2.10. In the anterior drawer test, the ACL is stressed by pulling the tibia anteriorly at 90° of flexion.
