Position of the foot during measurement. For anterior drawer stress (A), the specimen was fixed in the lateral position with the knee joint flexed at 30 degrees, and anterior drawer stress was applied approximately 3Â cm proximal to the lateral malleolus. For inversion stress (B), the specimen was positioned in supine with the knee joint flexed at 30 degrees, and inversion stress was applied approximately 5Â cm proximal to the medial malleolus. The angle conditions for both the anterior drawer and inversion stresses included 0-degree dorsiflexion, 15-degree plantar flexion, and 30-degree plantar flexion, with a stress intensity of 120 N.
