The normally palpable prominences of the anteromedial and lateral tibial plateau in the flexed-knee position are not felt if the knee is PCL deficient and there is posterior subluxation. The tibia should be slightly externally rotated and the anterior tibial translation force (anterior drawer) should be applied from the posteromedial aspect. [14], The Lachman test is widely regarded as the most useful test for diagnosing an acute ACL injury and should be used in conjunction with the pivot shift test and anterior drawer test for assessing ACL integrity. According to Larson, 4 the Lachman test proved to be the most sensitive test for an ACL rupture.

Remember that the test can be subject to errors, depending on the strength of the operator and the patient's posture. 0% average accuracy. [12], Additionally, false-positive Lachman tests can be associated with isolated posterior cruciate ligament injury and should be interpreted with caution in patients with suspected posterior cruciate ligament (PCL) injury diagnosed with either a positive posterior drawer sign or positive posterior sag sign. Most are rarely dangerous. Magnetic resonance imaging is the primary study used to diagnose ACL injury in the United States. Now talking about ACL, what ACL does? Naendrup JH, Patel NK, Zlotnicki JP, Murphy CI, Debski RE, Musahl V. Education and repetition improve success rate and quantitative measures of the pivot shift test. In this position in particular, the stabilizing function of the anterior cruciate ligament is essential in changing direction and braking. At the same time, the examiner uses the other hand to grasp the proximal tibia just below where the patients knee bends. Abulhasan J, Snow M, Anley C, Bakhsh M, Grey M.

If an ACL injury is detected, the patient is usually referred to an orthopedist. [11]A retrospective study reported that Lachman test sensitivity might be improved with knee joint aspiration before the exam in patients with suspected hemarthrosis, which may limit exam accuracy. This test should only be performed after excluding a posterior cruciate ligament injury, in which the tibia would spontaneously displace posteriorly. The effect of the quadriceps is increased by immobilizing the foot on the examining table. Value of the physical examination.
