Abstract

We aimed to report outcomes of Bicondylar Tibial Plateau (BTP) fractures treated using Ilizarov fixation, and identify risk factors for developing post-traumatic radiographic osteoarthritis (ROA). Retrospective study of 80 BTP fractures managed with Ilizarov fixation. All fractures united, with only 3 cases of deep infection. ROA was evident in 12.5% at average 13 months post-injury. Increased tibial articular-widening associated with risk of developing ROA (p = 0.02). Ilizarov fixation is safe and reliable in the management of BTP fractures. Restoration of tibial articular-width at fixation associated with reduced risk of developing radiographic OA.
