[Tension changes of the anterior cruciate ligament in the movement process of the knee joint].

Relative tension of the anteromedial part of the anterior cruciate ligament of five cadaver knees is measured. The ligament is taut at 80 degrees - 90 degrees flexion and loosened to a maximum at 30 degrees and 130 degrees flexion. On internal rotation it is taut at each stage of flexion, on external rotation, only at full extension and full flexion.
