Treatment of Instability of the Proximal Tibiofibular Joint by Dynamic Internal Fixation With a Suture Button

Injury to the proximal tibiofibular joint can lead to lateral knee pain and instability owing to chronic rupture of the posterior tibiofibular ligament. The condition is often missed, and the true incidence is unknown. A variety of surgical treatments have been proposed over the last decades. Methods such as arthrodesis and fibular head resection have largely been replaced with various reconstruction techniques using autografts. The purpose of this report is to describe our method for treatment of proximal tibiofibular joint instability by dynamic internal fixation with a suture button.
