During the anterior drawer test, knee position is?

• A. 0 degrees
• B. 45 degrees
• C. 90 degrees
• D. 120 degrees

Answer: (C)

The anterior drawer test assesses the ACL by measuring how far the tibia can move forward relative to the femur when a forward force is applied. This is best done with the knee bent to about ninety degrees because this angle places the ACL as the primary restraint to anterior tibial translation while the hamstrings are relatively relaxed and less able to oppose the motion. If the ACL is torn, you’ll see greater anterior translation and a softer end feel compared with the uninjured knee. Performing the test at this angle improves reliability and helps distinguish ACL injuries from issues that only appear at other degrees of flexion.
