    BackgroundThe incidence of deep vein thrombosis (DVT) and pulmonary embolism (PE) after total joint arthroplasty (TJA) procedures are lower in Asian populations than in Caucasian populations. Therefore, the need for thromboprophylaxis in Asian patients undergoing TJA remains inconclusive. The aim of this study was to validate the clinical outcomes of thromboprophylaxis in selective TJA patients in a Taiwanese population.MethodsWe retrospectively reviewed records of patients who underwent TJA procedures performed by a single-surgeon between January 2010 through December 2019. Patients received thromboprophylaxis with a combination of enoxaparin and low-dose aspirin if they fulfilled any of the following criteria: 1) body mass index >30 (kg/m 2 ), 2) presence of varicose veins, 3) history of DVT or PE, or 4) simultaneous bilateral TJA procedure. We assessed the incidence of DVT and PE, 90-day postoperative complications, length of stay, in-hospital mortality, 30-day and 90-day readmission, and 1-year reoperation.ResultsOf the 7511 patients included in this study, 2295 (30.6%) patients received thromboprophylaxis. For patients who received thromboprophylaxis(N = 2295), the incidence of DVT and PE were 0.44% and 0%, respectively. For patients who did not receive thromboprophylaxis (N = 5216), the incidence of DVT and PE was 0.46% and 0.04%, respectively. The overall rates of 90-day postoperative complications (2.3%), 30-day (1.8%) and 90-day readmission (2.3%), and 1-year reoperation (1.1%) were low.ConclusionProviding thromboprophylaxis for selective TJA patients within the Taiwanese population was effective, as indicated by the low incidence of DVT and PE. Complications, such as surgical site infection, should be carefully weighed and managed.Copyright © 2023, the Chinese Medical Association.
