Plays: 384

Video Description

A Lachman Test is a physical exam maneuver used to diagnose an ACL tear.

Technique: One hand secures and stabilizes the distal femur while the other firmly grasps the proximal tibia. A gentle anterior translation force is applied to the proximal tibia. A firm / solid or soft endpoint indicates the ACL is intact. Significant anterior translation as seen in this video suggest ACL deficiency.Lerat JL, Moyen BL, Cladière F, Besse JL, Abidi H.
