Contraction of the quadriceps can also cause meniscal impingement where loosening of the posterior attachment of the medial meniscus accompanies the insufficiency of the medial ligaments and anterior cruciate. After that, the examiner slightly externally rotates the tested leg, so the patients knee should point outward. This is to avoid action by secondary stabilizers and also that it is not posteriorly subluxated prior to initiation of the physical test (as occurs in a PCL-deficient knee).
