Abstract
Total ankle arthroplasty has become an increasingly used alternative to ankle arthrodesis
for the treatment of end-stage ankle arthritis. However, despite progressive technological
advances and the advent of multiple commercial implant systems, some concern remains
for the relatively high complication and failure rates. The objective of the present
investigation was to perform a systematic review of the incidence of complications
in obese patients undergoing total ankle arthroplasty. We performed a review of electronic
databases with the inclusion criteria of retrospective case series, retrospective
clinical cohort analyses, and prospective clinical trials with ≥15 total participants,
a mean follow-up period of ≥12 months, ≥1 defined cohort with a body mass index of
≥30 kg/m2, and a reported incidence rate of complications requiring revisional surgery at the
final follow-up point. Four studies met our inclusion criteria, with a total of 400
implants analyzed. Of these, ≥71 (17.8%) developed a complication requiring a revisional
surgical procedure. The most commonly reported surgeries were revision of the metallic
components and ankle gutter debridement. It is our hope that our investigation will
allow foot and ankle surgeons to more effectively communicate the perioperative risk
to their patients during the education and consent process.
