Prone Anterior Drawer Test Special Test

What is it used for?

• Assessing the Anterior Talofibular Ligament (ATFL).
• Often considered more sensitive than the supine test because gravity helps relax the calf muscles.

How to Perform

• Position: Patient lies on their stomach (prone) with feet hanging off the end of the table.
• Stabilization: Press down on the back of the calf (lower leg) with one hand to stabilize it against the table.
• Action: Cup the heel with the other hand and push it downward (anteriorly) towards the floor.

Interpretation of Results

• Positive Test: Excessive anterior movement (dropping) of the foot compared to the uninjured side.
• Note: A "dimple" (suction sign) may appear on the outer ankle.
