Advanced Imaging

Advanced imaging is usually obtained. Stress radiographs may be useful (Figure 1) and have comparable accuracy with MRI in the diagnosis of ankle instability, 74% to 71%, respectively.[4] MRI, however, does provide the added benefit of visualizing concomitant pathology including peroneal tendon tears, osteochondral lesions, deltoid injury, and soft-tissue impingement. It is important to evaluate the patient for concomitant injuries because some reports demonstrate that up to 96.9% of patients with ankle instability have additional pathologies.[5]
