Execution:
- Patient is in supine position
- The examiner stands on the side to be examined and places the patient’s extended leg into internal rotation via the patient’s ankle. The dorsal 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 fully relax
- The examiner gently flexes and extends the knee gently and observers for anteromedial subluxation of the tibia
- In a second step, the flexion angle is increased
Positive Outcome: When the flexion angle is increased, the tibia will jolt backwards

| Comment: Lemaire (1967) described the test as a great assessment to confirm ruptures of the ACL in the anesthetized patient. However, he noted that it’s difficult to elicit anteromedial rotatory instability in the awake patient as patient’s can’t fully relax | |||||
