The plantar calcaneonavicular ligament, also known as the spring ligament, is an important static stabilizer of the medial longitudinal foot arch. Compromise of this ligament is a primary causative factor of peritalar subluxation, and it should be repaired in addition to treatment of tibialis posterior tendon abnormalities. Open repair of the ligament requires extensive soft-tissue dissection. The development of the high distal portal for posterior tibial tendoscopy allows repair of the ligament endoscopically. This, together with endoscopically assisted reconstruction of the tibialis posterior tendon, allows complete endoscopic treatment of stage 2 posterior tibial tendon deficiency. The major structure at risk is the medial plantar nerve. This technique is technically demanding and should be reserved for experienced foot and ankle arthroscopists.
