The injured leg moves 2 to 5 millimeters (mm) more than is normal for its range of motion, compared to the other leg. Moderate (grade 2). The injured leg moves 5 to 10 mm more than is normal for its range of motion, compared to the other leg. Severe (grade 3).

Is Lachman test accurate?

The Lachman (anterior displacement of tibial manually at 20° of flexion) is an accurate test for detecting ACL tear (mean sensitivity 84%) (2, 8, 9). Anterior drawer test and the pivot shift tests have a sensitivity of about 62 percent.

How do I test my ACL?
