The test is named after orthopaedic surgeon John Lachman, late Chairman of the Department of Orthopaedic Surgery and Sports Medicine at Temple University School of Medicine in Philadelphia, Pennsylvania. The original description was submitted by one of his colleagues, JS Torg.
The Lachman test is more sensitive than the anterior drawer test. For the Lachman test, the person lies down in supine position with the knee flexed at 20 degrees and the heel touching the bed. The tibia is then pulled forward. If there is 6 to 8 millimeters of laxity, with no definitive resistance when the knee is pulled, then the test is ...

These tests include the pivot-shift test, anterior drawer test, and Lachman test. The pivot-shift test involves flexing the knee while holding onto the ankle and slightly rotating the tibia inwards. [28] In the anterior drawer test, the examiner flexes the knees to 90 degrees, sits on the person's feet, and gently pulls the tibia towards ...

The pivot-shift test [1] is one of the three major tests for assessing anterior cruciate injury or laxity, the other two being the anterior drawer and Lachman test. However, unlike the other two, it tests for instability, an important determinant as to how the knee will function. [ 1 ]
Waddell, et al. (1980) described five categories of signs: Tenderness tests: superficial and diffuse tenderness and/or nonanatomic tenderness; Simulation tests: these are based on movements which produce pain, without actually causing that movement, such as axial loading and pain on simulated rotation
