Abstract
An increasing number of patients with hepatitis B virus (HBV) infection are progressing in age and are undergoing total joint arthroplasty (TJA) surgery in China. Less attention is provided to the special populations. This study aimed to evaluate the effect of HBV on TJAs. We retrospectively reviewed all patients who met the inclusion of undergoing elective primary hip and knee arthroplasties from 2013– 2016. Non-hepatitis B cohort was built to match the case cohort to identify whether HBV infection was a risk factor associated with postoperative complications. A total number of 197 patients who underwent primary TJAs were involved in the study, including 49 patients with hepatitis B and 147 non-hepatitis B subjects. Among all the patients with TJAs, we obtained a 5.5% HBV infection rate for the first time. Compared with patients without hepatitis B, patients with hepatitis B had higher rates (P < 0.01) of total complications (10.2% compared to 4.7%), surgery-related complications (6.1% compared to 3.4%), and general medical complications (4.1% compared to 1.3%) than the non-hepatitis B group. Patients with hepatitis B infection had a 21% increased risk (95% CI, 0.97–1.46; p < 0.01) of total complication compared with non-hepatitis B group. Similar results were obtained for medical and surgical complications. HBV infection had a 31% increased risk (95% CI, 1.02–1.62; p < 0.01) for medical complication and 18% risk (95% CI, 0.95–1.42; p < 0.01) for surgical complication. In the subgroup analysis, no difference was found between the surgical methods and sex, whereas a significant difference of CRP change level (P < 0.01) was found between HBV group and the matched group in the clinical laboratory values. This is the first study of patients with hepatitis B undergoing primary THA or TKA and demonstrates an increased risk of multiple perioperative complications in a Chinese population. In consideration of the large population of HBV infection in China, more attention should be provided to patients with HBV infection who need to undergo TJAs.
