Sprunggelenkarthrodese nach gescheiterter Endoprothesenimplantation

Despite recent anatomical and biomechanical improvements the longevity of current total ankle replacements remains limited. Once total ankle replacement has failed conversion into ankle arthrodesis provides a viable option and should therefore be considered. However, due to the massive bone loss, precarious soft tissues and in order to preserve leg length, this kind of surgical treatment is considered to be technically demanding with potential impairment of the quality of life and decreased global foot and ankle function as well. The present article focuses on salvage ankle arthrodesis after failed total ankle replacement and seeks to provide a usable treatment algorithm.
