Pivot shift test: The pivot shift test is a dynamic test which also tests the integrity of the ACL.
No summary estimates could be calculated for the pivot shift test (due to a lack of available studies).
If the prior probability is low (say 10%, eg in general practice), a negative Lachman test will almost rule out an ACL rupture (probability decreasing from 10% to 2%), whereas a (difficult to perform and, therefore, less suitable) positive pivot shift test will result in referral to secondary care for further investigation (probability increasing from 10% to more than 60%).
Three common manual manipulations used to assess ligament laxity are the classic anterior/posterior drawer test, the Lachman test introduced by Torg et al (3), and the pivot shift test first described by Galway and Macintosh (4).

We present a new method to perform the pivot shift test that recalls the figure-of-four, or ashi-hishigi (knee lock), of judo, which easily allows the surgeon to perform the pivot shift test and varus-valgus stress test on those patients whose weight, height, or leg length may make the classic method more difficult.
