Midterm Outcomes Following Conversion of Failed Ankle Arthrodesis to Total Ankle Arthroplasty, Including Patients With a Deficient Fibula.

ABSTRACT:

Background

Previous studies of conversion of failed ankle arthrodesis to total ankle arthroplasty showed failure in patients with an absent distal fibula, and more recently that has been considered a contraindication. However, these conclusions were based on limited case series with older prosthetic designs, and the potential for successful conversion in this challenging patient population remains unclear. This retrospective study examines the midterm follow-up of 21 patients treated for a conversion of failed ankle arthrodesis by a single surgeon using a standard technique with a single prosthesis, with a focus on the treatment of 5 patients with a deficient distal fibula.

Methods

Between May 2010 and August 2019, 27 patients underwent conversion using a prosthesis with an
