Posterior tibial tendon dysfunction (PTTD) is a progressive disorder secondary to advanced degeneration of the posterior tibial tendon, leading to the abduction of the forefoot, valgus rotation of the hindfoot, and collapse of the medial longitudinal arch. Eventually, the disease becomes so advanced that it begins to affect the deltoid ligament over time. This attenuation and eventual tear of the deltoid ligament leads to valgus deformity of the ankle. Surgical correction of PTTD is performed to protect the ankle joint at all costs. Generally, this is performed using osteotomies of the calcaneus and repair or augmentation of the deltoid ligament. Unfortunately, there has been no universal procedure adapted by foot and ankle surgeons for repair or augmentation of the deltoid ligament. Articles have discussed the use of suture and suture anchors, suture tape, nonanatomic allograft repair, nonanatomic autograft repair with plantaris, peroneal and extensor halluces longus tendons to repair and augment the deltoid ligament. There is very little literature, however, in regard to using the posterior tibial tendon to augment the deltoid ligament in accordance with hindfoot fusion for end-stage PTTD deformity. In general, the posterior tibial tendon in triple and medial double arthrodesis is generally removed because it is thought to be a pain generator. This article presents a case study and novel technique using the posterior tibial tendon to augment and repair the laxity of the deltoid ligament in an advanced flatfoot deformity. Copyright © 2018.
