This test should only be performed after excluding a posterior cruciate ligament injury, in which the tibia would spontaneously displace posteriorly. The Lachman test directly assesses the integrity of this anatomical relation.[2]. Endpoints are graded from hard to soft, and have been nominally classified as A (firm, hard endpoint) or B (absent, soft endpoint). A soft end point and hemarthrosis suggest a complete tear; a soft end point without hemarthrosis suggests a chronic complete tear. Heres a step-by-step guide on how a doctor performs the Lachman test: There are two main benchmarks that the Lachman test uses to assign a grade to your ACL injury: Your doctor will likely conduct the Lachman test on your other leg, too, to compare its motion to that of your possibly injured leg. found that in the hands of an experienced clinician, accuracy of this test was 1: The sensitivity and specificity of the Lachman test knee increases to 100% if the patient was anesthetized 2. Using observations of both of your legs with the two criteria above, your doctor grades your injury on this scale: Some doctors prefer to use an instrument known as the KT-1000 arthrometer to get a more accurate reading of the legs range of motion. It is often best to examine the patient immediately after the injury or at least within several hours for a suspected ACL injury to avoid evaluating a knee with significant swelling and hemarthrosis, which may lead to patient guarding and negatively impact testing accuracy.

Accuracy and reliability of anterior cruciate ligament clinical examination in a multidisciplinary sports medicine setting. The Lachman test is used to check for an anterior cruciate ligament (ACL) tear or injury in the knee joint. Tibial translation or movement of 5 mm or more than movement in the normal limb generally indicates a rupture of the ACL, and more than 2 mm of anterior translation of the affected knee compared to the unaffected knee is considered a positive test indicating ACL injury. This could give you the impression that there is a lot of tibia movement while conducting the Lachman test for the ACL tear. The test is performed with the patient in a relaxed supine position.

[5] Results have suggested that the pivot shift test has a lower sensitivity than the Lachman test because it is generally a harder test to perform in the acute setting due to patient guarding. [5], The test is considered positive if there is excessive anterior translation of the proximal tibia greater than the uninjured side and also a lack of a firm endpoint.

In the absence of ACL, the tibia will move forward and cause the knee to buckle out. Another test for diagnosis is the Pivot shift test which is done by going from extension to flexion of the knee,and the tibia will be reduced at 20-30 degrees of flexion.The test measures the functional instability of the knee or the giving away of the knee.Pivot shift is pathognomonic for a ACL tear and is best demonstrated in the chronic setting.It is a more difficult test than the Lachman test. The test relies on proper positioning and technique and is regarded as the most sensitive and specific test for diagnosing acute ACL injuries. It is often best to examine the patient immediately after the injury or at least within several hours for a suspected ACL injury to avoid evaluating a knee with significant swelling and hemarthrosis, which may lead to patient guarding and negatively impact testing accuracy. The clinician should ask about the timing of the injury, the mechanism, joint swelling, functional ability, joint instability, and associated injuries while performing an appropriate history and physical exam in a patient with a suspected ACL injury.
