Liver Disease Increases the Risk of Postoperative Complications in Patients Undergoing Aseptic Revision Total Hip and Knee Arthroplasty

Background: Due to the multiorgan effects of liver disease, surgical patients with liver disease have an increased risk of perioperative complications. With revision total hip and knee arthroplasty surgeries increasing, it is important to determine the effects of liver disease in this patient population. The purpose of this study was to evaluate the impact of underlying liver disease on postoperative outcomes following revision total joint arthroplasty (TJA). Methods: The National Surgical Quality Improvement Program database was used to identify patients undergoing aseptic revision TJA from 2006-2019 and group them based on liver disease. The presence of liver disease was assessed by calculating the Model for End-Stage Liver Disease-Sodium score. Patients with a Model for End-Stage Liver Disease-Sodium score of > 10 were classified as having underlying liver disease. In this analysis, differences in demographics, comorbidities, and postoperative complications were assessed. Results: Of 7102 patients undergoing revision total hip arthroplasty, 11.6% of the patients had liver disease. Of 8378 patients undergoing revision total knee arthroplasty, 8.4% of the patients had liver disease. Following adjustment on multivariable regression analysis, patients with liver disease undergoing revision total hip arthroplasty or revision total knee arthroplasty had an increased risk of major complications, wound complications, septic complications, bleeding requiring transfusion, extended length of stay, and readmission compared to those without liver disease. Conclusions: Patients with liver disease have an increased risk of complications following revision TJA. A multidisciplinary team approach should be employed for preoperative optimization and postoperative management of these vulnerable patients to improve outcomes and decrease the incidence and severity of complications.
