Hepatitis C Antiviral Treatment Decreases All-Cause Complications After Total Joint Arthroplasty Regardless of the Presence of Fibrosis

BackgroundPatients with hepatitis C virus (HCV) have an increased risk of complications after total joint arthroplasty (TJA). There is a limited but growing body of evidence on the benefit of preoperative antiviral treatment to reduce complications after TJA. What has not been well established is the effect of preoperative antiviral treatment among those with advanced disease as indicated by hepatic fibrosis.MethodsIn total, 270 patients at 2 urban medical centers were reviewed for patient demographics, comorbidities, HCV treatment, hepatic fibrosis status, surgical information, and postoperative complications. Patients were divided into 2 groups based on their antiviral treatment status prior to TJA: Treated (n = 129) and Untreated (n = 141). Pearson’s chi-squared test, Student’s t-test, and multivariate logistic regressions were used to analyze complications between groups.ResultsPatients in the Treated group had significantly fewer all-type complications (4.7% vs 14.9%, P = .007), infections (2.3% vs 12.1%, P = .002), and reoperations (0.8% vs 9.9%, P = .001) compared to the Untreated group. After controlling for hepatic fibrosis, we found that Treated patients still had significantly lower odds of experiencing all-type complications (odds ratio OR] 0.30, 95% confidence interval CI] 0.10-0.88; P = .028), infection (OR 0.19, 95% CI 0.04-0.87; P = .033), and reoperation (OR 0.11, 95% CI 0.01-0.90; P = .039) following TJA.ConclusionHCV antiviral treatment reduces postoperative complications after primary TJA, even among those who have progressed to hepatic fibrosis. Surgeons can use this information in shared decision making prior to TJA to counsel patients about the benefits of preoperative antiviral treatment even in the presence of hepatic fibrosis.
