Lemaire Jolt test | Anteromedial Rotatory Instability<\/h2>\nLemaire (1967)<\/a> described this test as a great test to confirm ruptures of the anterior cruciate ligament in the anesthetized patient. However, he noted that it\u2019s hard to elicit anterolateral rotatory instability in the awake patient as patients can\u2019t fully relax. Furthermore, this test hasn\u2019t been assessed on its diagnostic ability so the clinical value is questionable.\n

Standing on the side to be examined, the leg is extended and brought into internal rotation by one hand that\u2019s grasping the ankle. The dorsum of the other hand is placed behind the head of the fibula and tendon of the biceps femoris in order to apply a ventrally directed force. The patient is asked to relax completely.\nThe knee is then gently flexed and extended repeatedly and the examiner observes for anteromedial subluxation of the tibia.\nIn the second step, the flexion angle is increased which will result in jolting backward of the tibia indicating a positive test.\n\nOther common tests to assess for rotatory instability of the knee are:\n
