ABSTRACT
PURPOSE@#To compare the MRI findings of anterior talofibular ligament (ATFL) and calcaneofibular ligament (CFL) injuries in chronic lateral ankle instability (CLAI) between surgical treatment groups.@*MATERIALS AND METHODS@#Fifty-two patients with CLAI were divided into the modified Broström procedure (MBP) (n = 31) and lateral ankle ligament reconstruction (LAR) (n = 21) groups. T2-weighted MRI findings between the groups were compared for caliber change, slope, signal intensity, and thickness measurements of the ligaments. Additionally, the talar tilt angles were measured on stress radiographs.@*RESULTS@#The injured ATFL (p = 0.002 vs. p = 0.001) and CFL (p = 0.008 vs. p = 0.039) were more commonly scarce or thin and had decreased slopes in the LAR group. The mean thickness of ATFL (P = 0.002) and CFL (p = 0.002) was 1.1 ± 0.9 mm and 1.3 ± 0.8 mm, respectively, in the LAR group and 2.2 ± 1.3 mm and 2.1 ± 0.9 mm, respectively, in the MBP group. The mean talar tilt angle was greater in the LAR group (13.4 ± 3.9°) than in the MBP group (9.5 ± 3.8°) (p = 0.001).@*CONCLUSION@#A qualitative analysis of the ligaments on MRI is valuable in selecting the surgical method.
