Abstract

This review describes a case of chronic post-traumatic foot drop managed with posterior tibial tendon transfer through the interosseous membrane and percutaneous Achilles tendon lengthening. Key technical considerations and postoperative rehabilitation principles are highlighted. This approach provides a durable solution for restoring ankle dorsiflexion and improving ambulation in patients with irreversible peroneal nerve injury.
