Salvage Arthrodesis for Failed Total Ankle Replacement.

Salvage arthrodesis for failed total ankle replacement can be a successful procedure. The decision to perform salvage arthrodesis is based on many factors, but the following are the most important indications: severe loss of bonestock (tibia, talus, or both), inadequate soft tissue coverage, or the inability to eradicate an infection. With few revision implants on the market, salvage arthrodesis is currently the most common treatment for failed replacement and justification for revision ankle replacement is limited when any of these factors are present.
