Anterior drawer test

Positioning.

The subject lies in the supine position with the knee flexed to a right angle, and the
heel resting on the couch. The examiner sits on the foot of the subject. One hand is on the anterior aspect of the knee: apex patellae in the palm of the hand, thenar and hypothenar making contact with the femoral condyles. The other hand is at the back of the upper tibia.

Procedure.

Draw the tibia forwards with the posterior hand and add a strong jerk when
the movement comes to a stop. The hand on the patella stabilizes the thigh.

Common mistakes.

None.

Normal functional anatomy:

• Range: in a normal joint the tibia shifts over only a few millimetres
• End-feel: hard ligamentous
• Limiting structures: anterior cruciate ligament.

Common pathological situations:

• Pain is indicative of a small lesion of the anterior cruciate ligament.
• Increase in range is seen in ruptures of the anterior cruciate ligament and I or the posterior capsule.
