[The physical diagnosis and treatment of insufficiency of the anterior cruciate ligament].

The role of the anterior cruciate ligament is considered in this work from the standpoints of anatomy and biomechanics. The authors are supporters of early and active operative management of acute injuries of the ligament and chronic instability of the knee joint. To improve early diagnostics of injuries of the anterior cruciate ligament the positional anterior drawer test was developed. Positive results of this test were compared with those of well-known tests for the insufficiency of the anterior cruciate ligament and it was recommended for diagnosing the anterior instability of the knee joint.
