Lachman Test

Excerpt

The Lachman test is a physical examination maneuver used to assess the integrity of the anterior cruciate ligament in a suspected anterior cruciate ligament (ACL) injury. The test is used to evaluate the anterior translation of the tibia in relation to the femur and is considered a variant of the anterior drawer test. Multiple studies have shown that the Lachman test is the most sensitive and specific in the diagnosis of acute ACL tears, and generally superior to both the anterior drawer test and the pivot shift test.
