THE RELIABILITY AND DIAGNOSTIC ACCURACY OF ASSESSING THE TRANSLATION ENDPOINT DURING THE LACHMAN TEST

摘要

BackgroundInterpretation of Lachman testing when evaluating the status of the anterior cruciate ligament (ACL) typically includes a numerical expression classifying the amount of translation (Grade I, II, III) in addition to a categorical modifier (Grade A [firm] or B [absent]) to describe the quality of the passive anterior tibial translation's endpoint. Most clinicians rely heavily on this tactile sensation and place value in this judgment in order to render their diagnostic decision; however, the reliability and accuracy of this endpoint assessment has not been well established in the literature.
