title: Arthroscopic Repair of Superomedial Spring Ligament by Talonavicular Arthroscopy.
abstract: A spring ligament tear can occur because of failure of the tibialis posterior tendon in adult-acquired flatfoot deformity or as an isolated injury with a normal tibialis posterior tendon. The superomedial spring ligament is the most common site of rupture. Compromise of this ligament is a primary causative factor of peritalar subluxation, and a functioning tibialis posterior tendon cannot prevent or correct a planovalgus foot deformity. Therefore, the spring ligament should be repaired in addition to treatment of tibialis posterior tendon abnormalities. The purpose of this technical note is to describe a minimally invasive approach for repair of the superomedial spring ligament by talonavicular arthroscopy.
