Ankle Alignment on Lateral Radiographs

Description: In ankles with end-stage osteoarthritis or after total ankle replacement (TAR), radiographic landmarks based on joint surface morphology are usually obscured and thus inadequate for measurement. Two candidate measures for quantifying AP tibial-talar alignment without relying on those landmarks were identified in a corollary cadaver-based study. This study aimed to verify reliability and validity of those candidate measures.
