Agility to INBONE: anterior and posterior approaches to the difficult revision total ankle replacement

Clin Podiatr Med Surg. 2013 Jan;30(1):81-96. doi: 10.1016/j.cpm.2012.08.011.


Total ankle replacement is now acknowledged as a viable alternative to ankle arthrodesis for end-stage ankle arthritis. The authors present a series of 14 patients who were converted from the Agility total ankle replacement to an INBONE total ankle replacement. This report is unique in that anterior and posterior approaches are discussed and detailed. Although the authors present successful conversion of the Agility total ankle replacement to an INBONE total ankle replacement, the difficulty of this procedure is demonstrated by the high complication rate and 2 early failures.
