Results

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.
