Bone augmentation for revision total ankle arthroplasty with large bone defects

Until recently, revision arthrodesis was the standard salvage procedure for failed total ankle arthroplasty (TAA) (Groth and Fitch 1987, Kotnis et al. 2006, Culpan et al. 2007, Doets and Zurcher, 2010, Henricson and Rydholm 2010). However, recent studies have investigated the efficacy of revision TAA (Espinosa and Wirth 2013, Hintermann et al. 2013 , Zgonis 2013) but most of them have not specifically addressed the problem of deficient bone stock. This technical note shows how to perform revision TAA in patients with substantial bone loss.
