Arthroscopic Lachman test: a new technique using anatomic references

Abstract

Using familiar anatomic references viewed during a standard arthroscopic evaluation, an arthroscopic Lachman test can help the surgeon identify anterior cruciate ligament deficiency. This test is especially useful in those patients where a false-negative report as a result of guarding, meniscal tears or other factors is suspected. Additionally, this test can be used after anterior cruciate ligament reconstruction to verify that the abnormal anterior laxity has been eliminated. Arthroscopy 1998 Sep;14(6):641-2
