The anterior drawer test assesses integrity of which ligament?

Explanation:
This test evaluates anterior tibial translation to gauge ACL integrity. The ACL resists forward movement of the tibia relative to the femur, especially when the knee is bent about 90 degrees. If the ACL is intact, the tibia doesn’t move much and you feel a firm end point when you pull. If the ACL is torn, there is increased anterior translation of the tibia and a soft or absent end point, indicating laxity. The maneuver is not designed to test the collateral ligaments or the PCL—the PCL resists backward movement and is assessed with a posterior drawer test, while the MCL and LCL are evaluated with varus/valgus stress tests.
