ABSTRACT
The purpose of this study was to compare complication rates of total ankle replacement
in 2 groups of patients based on their body mass index (BMI). The total cohort was
divided into 2 groups based on BMI. Group 1 included patients with a BMI ≤30 kg/m2. Group 2 included patients with a BMI >30 kg/m2. Available charts were reviewed for patients who underwent primary total ankle arthroplasty.
Patient demographics, BMI, prosthesis used, concomitant procedures, and intraoperative
and postoperative complications were recorded. Ninety-seven patients met the inclusion
criteria and underwent total ankle replacement between March 2012 and July 2016. Mean
follow-up was 26.3 (range 12 to 62) months. Mean age was 66.4 (range 23 to 85) years.
Mean BMI was 29.6 (range 20.6 to 49.5) kg/m2. Forty-three males and 54 females were included. There were 53 patients in group
1 (BMI ≤30 kg/m2) and 44 patients in group 2 (BMI >30 kg/m2). Total complication rates for group 1 and 2 were 18.9% (10 of 53) and 11.4% (5 of
44), respectively. There were a total of 10 minor complications and 5 major complications.
There was no statistical difference between the groups (p = .308) in terms of complication rates. All patients underwent at least 1 concomitant
procedure at the time of the index ankle replacement. We found that total ankle replacement
can be safely utilized in patients with a BMI >30 kg/m2. In the present study, there was no statistical significance in complication rates
in the 2 groups.
