The ATFL courses from the anterior aspect of the lateral malleolus to the anterior medial aspect of the neck of the talus. Importance of Test: The anterior drawer test is a beneficial test to perform in a patient following an inversion ankle sprain (injury to the lateral collateral ligaments). The 3 main components of the Lateral Collateral Ligaments of the ankle include the anterior talofibular ligament (ATFL), calcaneofibular ligament, and posterior talofibular ligament. Positive test results are often graded on a "0 to 3 scale", with 0 indicating no laxity & 3 indicating gross laxity.ĭiagnostic Accuracy: Sensitivity. A positive test results if the talus translates forward. The examiner then places the patient's foot into 10-15 degrees of plantar flexion and translates the rear foot anteriorly. Performing the Test: The examiner stabilizes the anterior distal leg with one hand & grasps the patient's calcaneus and rear foot with their second hand. This test primarily assesses the strength of the Anterior Talofibular Ligament. ![]() Purpose: To test for ligamentous laxity or instability in the ankle.
