Proximal Tibiofibular Joint Reconstruction With a Semitendinosus Allograft for Chronic Instability

Whereas acute proximal tibiofibular joint (PTFJ) dislocation may require urgent reduction, chronic or recurrent instability may initially be approached with conservative treatment. Indications for PTFJ reconstruction include persistent lateral knee pain and/or tibiofibular instability for which conservative treatment has failed. Owing to the low incidence of diagnosed isolated PTFJ instability, there is still no consensus regarding the optimal surgical treatment, with an array of options having been previously described. We describe the treatment of isolated PTFJ instability using an anatomic reconstruction with semitendinosus allograft for chronic instability.
