Anteromedial impingement of the ankle: using MR arthrography to assess the anteromedial recess.
OBJECTIVE
Our objective was to describe the appearance of the anteromedial tibiotalar joint on MR arthrography in patients with clinically and arthroscopically confirmed anteromedial impingement.


CONCLUSIONS
Anteromedial impingement of the ankle is now being recognized in the orthopedic literature as a distinct entity. MR arthrographic findings of anteromedial impingement include capsular and synovial soft-tissue thickening anterior to the tibiotalar ligaments and any associated osseous abnormality. Although anteromedial impingement is uncommon compared with other impingement syndromes of the ankle, the radiologist should be aware of the diagnosis and possible findings on cross-sectional imaging.
