The purpose
of this study was to investigate the arthro-sonographic appearance of the chronic anterior talofibular ligament (ATFL) injury. Twenty-nine patient, who were identified to have partial or complete ATFL tears by conventional ultrasonography were included. Intraarticular injection of 5 mL of fluid (2.5 cc lidocaine+2.5 saline) was performed under ultrasound-guidance, which was followed by arthrosonography. Among 23 patients with partial tear which was detected by the conventional ultrasonography, 11 patients were identified to have complete tear by the arthrosonography. Among 6 patients with complete tear was detected by conventional ultrasonography, all of them identified to have complete tear by the arthrosonography. Arthrosonography is helpful in evaluation the configuration of ATFL complete tear and detecting complete tear by making them appear larger and apparent after instillation of fluid.
