Arthroscopic Reconstruction of the Anterior Talofibular Ligament, Lateral Talocalcaneal Ligament, and Calcaneofibular Ligament Using a Triangle-Shaped Tendon Graft (ALC-Triangle).


ABSTRACT: The lateral talocalcaneal ligament (LTCL) connects the talus and calcaneus on the lateral side of the hindfoot. Although its function remains has not yet been clearly elucidated, the LTCL is thought to be important for the stabilization of the subtalar joint. Ankle sprains often include not only the talocrural joint but also the subtalar joint; therefore, LTCL injuries occur at a certain rate. Moreover, surgeons often encounter and reluctantly dissect the LTCL during arthroscopic anterior talofibular ligament (ATFL) and calcaneofibular ligament (CFL) reconstruction because the LTCL connects to the ATFL at the talus in 42% of people and connects to the CFL at the calcaneus in 18% of people. As a result, LTCL reconstruction might be necessary for those patients. We describe the arthroscopic reconstruction technique of the ATFL, LTCL, and CFL using a triangle-shaped tendon graft (ALC-triangle). This technique provides a possible advantage of an anatomical and stable talocrural joint and subtalar joint.
