Split peroneus longus tenodesis for chronic lateral ligamentous instability of ankle

A new procedure is described that uses a split peroneus longus tendon to reconstruct the anterior talofibular and calcaneofibular ligaments for chronic post-traumatic lateral ligamentous instability of the ankle for patients who wish to return to sporting activities. Subtalar inversion, which is essential for many sporting activities, is not affected. It is not a difficult procedure. In this small series of four patients followed out of six, over a period of 6 years with an average follow-up of 31.7 months, it has given good results, both subjectively and objectively, enabling them to return to active sports.
