The posterior tibial tendon functions as a primary stabilizer of the medial longitudinal arch of the foot. Posterior tibial tendon dysfunction accounts for 80% of cases of adult-acquired flatfoot deformity. It is classified into 4 stages based on the function of the tibialis posterior tendon, the reducibility of the deformity, and the condition of the ankle joint. The purpose of this Technical Note is to describe the technical details of endoscopically assisted reconstruction of theposterior tibial tendon for stage 2 posterior tibial tendon dysfunction. It consists of using the medial half of the anterior tibialis tendon as a primary transfer and augmentation by the flexor digitorum longus. This construct is then protected with a subtalar arthroereisis.
胫后肌腱作为足内侧纵弓的主要稳定结构发挥作用。胫后肌腱功能障碍占成人后天性平足畸形病例的80%。根据胫后肌腱的功能、畸形的可复性以及踝关节的状况，其被分为4个阶段。本技术说明的目的是描述内镜辅助下对2期胫后肌腱功能障碍进行胫后肌腱重建的技术细节。它包括使用胫骨前肌腱的内侧半作为主要移位肌腱，并通过趾长屈肌进行增强。然后用距下关节制动术对该结构进行保护。
