The Anterior Drawer Sign and Lachman Test are utilized for the evaluation of which injury?

The Anterior Drawer Sign and Lachman Test are both clinical tests specifically designed to assess the integrity of the anterior cruciate ligament (ACL) in the knee.

In the Anterior Drawer Sign test, the examiner pulls the tibia forward while stabilizing the femur. A significant forward movement of the tibia compared to the femur indicates a potential ACL injury. Similarly, the Lachman Test involves flexing the knee at about 20 to 30 degrees and then applying an anterior force on the tibia. A positive test will show increased anterior translation of the tibia relative to the femur, further confirming ACL instability.

Both tests are widely considered the gold standard for evaluating ACL injuries due to their high sensitivity and specificity, making them invaluable in the assessment of knee ligament injuries. Other choices, like PCL injuries or meniscal tears, utilize different diagnostic methodologies and have distinct clinical focus points, thus distinguishing them from the assessment of ACL injuries. The fracture of the tibia is diagnosed using imaging rather than these physical examination tests.
