Lachmann's test determines anterior cruciate integrity.

The knee is flexed at 20-30 degrees and the leg is stabilized by the examiner sitting on the foot. The hamstrings should be relaxed. The leg and thigh are grasped firmly and moved in opposite directions.

Antero-posterior displacement of the tibia on the femur with the knee at 20-30 degrees and the muscles relaxed is a positive result.
