What are the important risk factors that predispose a patient to infection after total ankle arthroplasty (TAA)?

Authors: Eric Senneville, Amiethab Aiyer, Niall Smyth

RECOMMENDATION: There is evidence indicating that the following risk factors may predispose a patient to an infection after a TAA: inflammatory arthritis, prior ankle surgery, body mass index (BMI) < 19 and peripheral vascular disease. Meanwhile, there is conflicting evidence (which may be due to patient selection bias) indicating that the following risk factors may predispose a patient to infection after a TAA: obesity (BMI > 30), tobacco use, diabetes, duration of surgery, age < 65 years, hypothyroidism, low preoperative American Orthopaedic Foot and Ankle Society (AOFAS) hindfoot score and chronic lung disease.
