Ten-Year Follow-Up of a Customized Total Talar Prosthesis for Revision Total Ankle Arthroplasty

Abstract

Case: A 74-year-old woman with rheumatoid arthritis had undergone total ankle arthroplasty (TAA) for severe ankle joint destruction at our hospital 14 years earlier. Radiographs of the ankle revealed displacement of the tibial component and subsidence of the talar component. Revision TAA was performed using a customized alumina ceramic total talar prosthesis. Conclusion: The 10-year outcome of revision TAA with a total talar prosthesis was satisfactory, with no postoperative complications, such as displacement of the tibial component, dislocation of alumina ceramic artificial talus, or progression of degenerative changes in the talonavicular and subtalar joints.
