Seven human knee cadaveric specimens were dissected down to joint capsule and fixed to a material testing machine at 30°of flexion. Three components of the force output from a universal force-moment sensor were recorded during an anterior translation of Lachman test before and after each soft tissue around the knee was cut off. By assuming the principle of superposition, the in situ force in each tissue was calculated. Results revealed that the in situ force in the anterior cruciate ligament (ACL) is approximately identical to the applied force to the knee, however ; in situ forces in other tissues were almost zero. It was also found that the in situ force in the posterior quarter of the anteromedial portion of the ACL (PQ) is larger than those in anterior quarter of the anteromedial portion of the ACL (AQ) and posterolateral portion of the ACL (PL).
