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. [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. Coffey R, Bordoni B. Lachman Test. The classic Lachman test presents problems not only for examiners with small hands, simultaneously immobilizing the thigh and lower leg can also be difficult for any examiner with an obese or muscular patient.
