title: Treatment of the arthritic valgus ankle.
abstract: The ankle joint is part of a biomechanical hindfoot complex. Approximately 1% of the world's adult population is affected by ankle osteoarthritis (AO). Trauma is the primary cause of ankle OA, often resulting in varus or valgus deformities. Only 50% of patients with end-stage ankle OA have a normal hindfoot alignment. The biomechanics and morphology of the arthritic valgus ankle is reviewed in this article and therapeutic strategies, including joint preserving and nonpreserving modalities are presented. Pitfalls are discussed and the literature is reviewed regarding outcomes in patients with valgus deformity who underwent total ankle replacement.
