A hard end point and hemarthrosis suggest an acute partial tear; a hard end point without hemarthrosis suggests a suspected chronic partial tear, elongation, or excessive laxity. [6], Correct technique is necessary for accurate test interpretation, as clinicians using proximal tibial placement were more likely to correctly interpret a Lachman test than those using a more distal tibial hand placement. This test is considered positive if there is a soft or mushy end feel to the translation of the tibia. The chronic injury group scored a positive Lachman test in 97% (conscious) and 99% (anesthetized). Prompt evaluation and diagnosis of ACL injuries by the interprofessional healthcare team are essential to expedite further management and rehabilitation.
