Introduction: The purpose of this study is to investigate the relationship between preoperative hyponatremia and postoperative complications in aseptic revision hip and knee arthroplasty.  Methods: Aseptic revision arthroplasties from 2007 to 2016 were collected using a large, United States database. Patients were stratified into eunatremic and hyponatremic cohorts. Rates of complications were collected and analyzed.  Results: 25,517 surgeries were evaluated. Preoperative hyponatremia was independently associated with organ/space infections (OR= 2.316; p<0.001), postoperative blood transfusions (OR= 1.467; p<0.001), pneumonia (OR= 2.05; p =0.002), sepsis (OR= 2.533; p<0.001), extended length-of-stay (OR= 2.221; p<0.001), minor complications (OR= 1.549; p<0.001), wound complications (OR= 1.505; p=0.001), pulmonary complications (OR= 1.72; p=0.007), and sepsis complications (OR= 2.305; p<0.001).
