Outcomes of Conversion of Ankle Fusion to Total Ankle Arthroplasty

With ankle replacements gaining popularity and documented good functional outcomes, there is an increasing number of patients inquiring about the possibility of converting an ankle fusion to a replacement. This could be due to pain, limited function, or increasing adjacent joint arthritis. There is an increasing body of evidence in the literature that a conversion to a replacement is possible and that the outcomes are positive. There are also absolute contradictions for a conversion. An absent fibula, pain of unknown origin, and recent infection fall in this category. Long-term follow-up is needed to see if conversions of ankle fusions to replacements have the same functional results and longevity as primary replacements.
