What is the purpose of the anterior drawer ankle test?

• A. To assess calcaneofibular ligament integrity.
• B. To assess anterior talofibular ligament integrity.
• C. To evaluate deltoid ligament stability.
• D. To test Achilles tendon flexibility.

Answer: (B)

The anterior drawer ankle test is used to assess the anterior talofibular ligament (ATFL) by checking how much the talus can move forward relative to the tibia. To perform it, the foot is placed in slight plantarflexion so the ATFL is taut, and the clinician stabilizes the tibia while gently pulling the calcaneus forward. If the talus translates forward more than what’s normal or the end feel is soft, that suggests ATFL injury or laxity, which is common after an inversion ankle sprain. A normal, firm end-feel with minimal forward movement indicates a intact ATFL.

This test specifically targets the ATFL; it doesn’t primarily assess the deltoid ligament, the calcaneofibular ligament, or the Achilles tendon, which are better evaluated with other maneuvers.
