The current classifications of "Lisfranc injury" can be purely ligamentous (low-grade midfoot sprains) or involve the osseous and articular structures (high-grade Lisfranc fracture displacements). The first type is often difficult to detect. If these patients are not properly treated, long-term disability can result. The rate of missed or delayed diagnoses has ranged from 13% to 24%, primarily owing to the subtlety of the radiographic findings. This is relatively more common in cases of subtle ligamentous injury (19%). The aim of the present report was to provide a new technique for missed or delayed Lisfranc injury without degenerative local signs. The Lisfranc ligament complex reconstruction is performed with a gracilis tendon graft and is protected by temporary screw fixation. We performed this technique in 3 patients. All 3 patients obtained good results, have been able to resume their previous activities, and have stated they would undergo this type of procedure again. The minimum follow-up length was 2 years.
