Predictors of Acute Ischemic Stroke After Total Knee Arthroplasty.

Predictors of Acute Ischemic Stroke After Total Knee Arthroplasty. J Surg Orthop Adv. 2017 FALL;26(3):148-153 Authors: Menendez ME, Greber EM, Schumacher CS, Lowry Barnes C Abstract Although acute ischemic stroke (AIS) is a feared medical complication after total knee arthroplasty (TKA), little is known about its incidence and risk factors. The purpose of this retrospective populationbased study using the Nationwide Inpatient Sample (2008-2011) was to determine the incidence and predictors of AIS following TKA. The rate of perioperative AIS was 0.08%. Patients undergoing bilateral TKA were almost three times more likely to develop AIS compared with unilateral TKA patients. The age group with the highest odds of AIS was ≥85 years. Sex and race and ethnicity were not independently associated with AIS. The comorbidity with the highest risk for AIS was history of stroke, followed by cardiac valvular disease, peripheral vascular disease, atrial fibrillation, complicated diabetes, coagulopathy, and ischemic heart disease. The data in this article might prove useful for preoperative counseling and decision making, resource allocation, and implementation of strategies to minimize the occurrence of AIS after TKA.
