The Lachman test is used to check for an anterior cruciate ligament (ACL) tear or injury in the knee joint. The test is named after John Lachman, an orthopedic surgeon at Temple University in Philadelphia who invented the technique. Lachmans test is the most sensitive examination test for ACL injury.The anterior cruciate ligament is located in front of the knee.The primary function of the ACL is to resist anterior translation of the tibia relative to the femur and provide some rotational stability to the knee.Rupture of the ACL is a condition commonly seen in sports due to a non-contact pivoting injury. Guyanese and Trinidadian name found among people of Indian origin : from the Hindu personal name Lakshman, from Sanskrit lasmna 'one who has auspicious marks'. Mark Dutton, Pt . Evaluating the patient with a knee injury. The diagnostic accuracy of ruptures of the anterior cruciate ligament comparing the Lachman test, the anterior drawer sign, and the pivot shift test in acute and chronic knee injuries. The manual test (30 degrees stress physical examination) does not require any instrumentation to diagnose an anterior cruciate ligament injury. (2014). iamque artuum et membrorum d [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. 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. A 2013 study that looked at 653 people with ACL ruptures found that the Lachman test had a 93.5 percent success rate, only 1 percent less accurate than the ADT. Slight anterior migration of the tibial head will be observed where the anterior cruciate ligament is intact. The literature does not contain articles or case reports that highlight complications in the Lachman test procedure. The patient will suffer pain during walking. The Lachman Test is commonly used in orthopedic examinations to test for anterior cruciate ligament (ACL) integrity. The motion must have a soft end point. A soft end point and hemarthrosis suggest a complete tear; a soft end point without hemarthrosis suggests a chronic complete tear. Then the examiner pushes the tibia anteriorly with respect to the femur. The Lachman test directly assesses the integrity of this anatomical relation.[2]. A soft endpoint is regarded as a forward translation of the tibia without a distinct, firm, clear endpoint. Courtesy: Prof Nabil Ebraheim, University of Toledo, Ohio, USA. What does a positive Lachman test mean? Your hips may feel tight due to overuse or inactivity.

Whats Causing This Pain in the Back of My Knee? The anterior cruciate ligament connects the two bones in the knee joint, the femur and the tibia. There we be no noticeable injury in the patients leg compared to the other leg. [15]A clinician should also examine and test for medial and lateral collateral ligament, posterior cruciate ligament, and meniscal injuries in conjunction with the Lachman test for a suspected ACL injury. The Lachman test is the most accurate test for detecting an ACL tear. PMID: Jonsson T, Althoff B, Peterson L, Renstrm P. Clinical diagnosis of ruptures of the anterior cruciate ligament: a comparative study of the Lachman test and the anterior drawer sign. At this angle, other knee structures move out of the picture and may not limit the anterior translation of the tibia. Apply quick posterior-to-anteriorly directed forces through the tibia. If the ligaments are intact, there will be no change in contour, or only a slight one as the tibial tuberosity moves slightly anteriorly. The ACL consists of 2 major bundles; the posterolateral bundle and the anteromedial bundle, which are named based on their tibial insertion. Insufficiency of the anterior cruciate ligament is therefore particularly evident in this position of the joint as it approaches extension due to the occurrence of lateral subluxation of the proximal tibia (pivoting). The Lachman Test is positive if there is excessive anterior translation of the proximal tibia greater than the uninjured side and also a lack of a firm endpoint indicating an anterior cruciate ligament injury. Explain the interprofessional team strategies for the prompt evaluation of patients with suspected anterior cruciate ligament (ACL) injuries to expedite diagnosis and management. A false-negative Lachman test may occur in these situations: In a concurrent PCL injury, the knee can be posteriorly subluxated at the beginning of the test. Next, an anterior force is applied to the proximal tibia in an attempt to sublux the tibia forward while keeping the femur stabilized. Am J Sports Med.

With a ACL rupture,the ACL will be lax and the examination will feel softer with no end point.The tibia can be pulled forward more than normal.Be aware that a PCL tear can cause posterior subluxation of the tibia and give rise to a false positive Lachmans test. Not hampered by posterior horn of meniscus, Less painful because the muscles are relaxed, Not hampered by sprained or partially ruptured medial collateral ligament. A soft end feel / endpoint is indicative of secondary structures stopping the continued anterior translation of the tibia. In the absence of ACL, the tibia will move forward and cause the knee to buckle out. [5], A modified Lachman test involves placing the examiners knee below the patients posterior thigh of the affected leg to create a more stable anchor when performing the test.
