Objective       To evaluate the significance of MR findings in patients with lateral ankle instability but asymptomatic ankles.       Methods      A total of 14 ankles in 11 asymptomatic patients were evaluated using 3.0 Tesla MR scanners. Imaging planes included axial PD and T2 weighted sequences

coronal fat-saturated PD fast spin sequence

sagittal T1 weighted sequence

and sagittal STIR sequence. Two musculoskeletal radiologists reviewed all images to reach consensus about abnormal findings.       Results      A total of 7/14 (50%) of subjects demonstrated abnormal anterior talofibular ligament (ATFL)

8/14 (57%) demonstrated abnormal calcaneofibular ligament (CFL)

and 2/14 (14%) demonstrated abnormal posterior talofibular ligament (PTFL). In addition

9/14 (64%) subjects were noted to have peroneal tendon pathology.       Conclusion       MR abnormalities in the lateral ligament complex and peroneal tendons can frequently be present in asymptomatic subjects.
