Effect of Obesity on Total Ankle Arthroplasty: A Systematic Review of Postoperative Complications Requiring Surgical Revision

Published:December 25, 2017DOI:


      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.
