Using the reverse anterior drawer method, the change in the anterior talofibular ligament length was 3.3 mm in the experienced group and 2.7 mm in the beginner group for the ligament injured patient. The length changes for the patient with intact anterior talofibular ligament were 0.5 mm and 0.4 mm in the experienced and beginner groups, respectively.

The examiners consisted of 10 experienced and 10 beginner examiners.The mean age of the experienced examiners was 43 years (range, 34 to 55 years) with 8.4 years (range, 5 to 17 years) of experience in ultrasonography. The mean age of the beginner examiners was 28 years (range, 26 to 35 years) with 0.7 years (range, 0 to 1 years) of experience.
Each examiner performed stress sonography on patients with an intact ATFL and an injured ATFL using the reverse anterior drawer method and anterior drawer method.
