摘要

Along with development of the implant, indication for TAA has been extended to the severe deformity due to osteoarthritis or rheumatoid arthritis. However, a certain rate of complication after TAA is still remaining. The main reasons for failed TAA are the complications of talar component such as aseptic loosening or subsidence. We developed artificial talar prosthesis and indicated for the patient with idiopathic necrosis of the talus. This time we applied this new implant combined with tibial component of the TAA for the patient with end-stage ankle arthritis having severe collapse of the talus. The purpose of this study is to evaluate the outcomes of TAA with artificial talus.Methods:【Materials】Thirteen patients (13 ankles) treated by TAA with artificial talus since 2007 to 2014 were investigated. The mean duration of follow-up was 35 months (range...
