• ABSTRACT
    • Common peroneal nerve dysfunction after a multiligament knee injury can be devastating. In patients with persistent foot drop, posterior tibial tendon transfer to the dorsum of the foot is a reliable and safe procedure to restore dorsiflexion. These authors favor passing the posterior tibial tendon through the interosseous membrane and docking it into the lateral/middle cuneiforms. A Strayer procedure or tendo-Achilles lengthening must be performed in patients unable to achieve at least 10° of passive dorsiflexion. Despite the operative limb having 30% to 40% of ankle dorsiflexion strength of the uninjured limb, short- and long-term functional outcomes are excellent.
