From: CT arthrography for demonstration of various articular injuries in post-sprained ankle pain
Right chronic predominately medial ankle pain after multiple episodes of sprains, and the current episode was lateral sprain. Axial CTA images through the talar neck (a, b) demonstrate lateral bowing of the ATFL, with loss of normal taut appearance (solid arrows), note thinning of the ligament proximally, also note fraying of its distal band (dashed arrow). Sagittal (c) and coronal (d) CTA show cartilage defects through medial and posterior aspects of the talar dome (black arrows) with variable thickness affection, note intact subchondral bone plate and lack of osseous injury. Note also uneven joint space widened anteriorly
