PTTD is the inflammation or overstretching of posterior tibial tendon in the foot. This tendon is located on the medial aspect of your foot and ankle. The key function of the posterior tibial tendon is to provide stability and support to the medial longitudinal arch in your foot. When the tendon becomes overstretched or torn it results in collapse of your medial arch leading to and acquired flatfoot. Adult acquired flat foot can occur in one foot, but can less commonly be seen in both. PTTD is generally a progressive condition and when left untreated the symptoms will continue to get worse.
