Proximal Tibiofibular Joint Stabilization With Concurrent Posterolateral Corner Reconstruction in Multiligamentous Knee Injury

Proximal tibiofibular joint (PTFJ) instability is a rare knee injury, accounting for less than 1% of knee injuries. It causes significant lateral sided knee pain and functional deficits and can be associated with up to 9% of multiligament knee injuries. Concurrent surgical treatment of posterolateral corner (PLC) and PTFJ instability poses technical challenges due to the limited working space of the fibula head and inherent risk of collision between grafts, bone tunnels, and implants. In this Technical Note, we detail our senior author's technique for PTFJ reconstruction without the use of additional bone tunnels or implants in the fibula head, to reduce the risk of overcrowding and tunnel collision.
