The posterior tibial tendon (PTT) is the most important dynamic stabilizer of the medial ankle and longitudinal arch of the foot. PTT dysfunction is a degenerative disorder of the tendon, which secondarily involves multiple ligaments, joint capsules, fascia, articulations, and bony structures of the ankle, hindfoot, midfoot, and forefoot. When the tendon progressively attenuates, the patient develops a painful, progressive collapsed flatfoot or pes planovalgus deformity. This comprehensive review illustrates the 3-Tesla magnetic resonance imaging (3T MRI) features of PTT dysfunction. In addition, the reader will gain knowledge of the expected pathologic findings on MRI, as they are related to clinical staging of PTT dysfunction.
胫后肌腱（PTT）是内侧踝关节和足纵弓最重要的动态稳定器。PTT功能障碍是一种肌腱退行性疾病，继而累及踝关节、后足、中足和前足的多条韧带、关节囊、筋膜、关节和骨结构。当肌腱逐渐变细时，患者会出现疼痛、进行性塌陷扁平足或扁平外翻足畸形。这篇综述阐述了PTT功能障碍的3特斯拉磁共振成像（3T MRI）特征。此外，读者将了解到MRI上预期的病理表现，因为它们与PTT功能障碍的临床分期相关。
