Revision Surgery for Failed Total Ankle Replacement.

Revision surgery for failed total ankle replacement is a challenge to the revision surgeon. Deformity, presence of infection, segmental bone defects, patient comorbidities, and soft tissue compromise all are significant considerations when determining appropriate procedures. Revision total ankle replacement, explant and fusion with or without lengthening, use of a trabecular metal cage, placement of an antibiotic cement spacer, grafting, and amputation all are viable options to treat patients with failed ankle arthroplasty.
