Anterior drawer test in external rotation

Positioning.

The subject is positioned as for the previous test. The lower leg and foot are externally rotated as far as is comfortably possible.The examiner places both hands around the upper part of the tibia with the index fingers on the hamstring tendons and the thumbs at the anterior border of the joint .

Procedure.

Draw the upper part of the tibia forwards and add a strong jerk at the end of the
movement.Normal findings. The range of movement in external rotation is slightly superior to the movement in a neutral position .

Common pathological situations.

A marked increase in range is indicative of anteromedial rotatory instability (ruptures of the anterior cruciate ligament, the posteromedial capsule and the medial collateral ligament).
