Abstract Objective To investigate the risk factors for deep vein thrombosis (DVT) following total hip arthroplasty (THA). Methods Patients who underwent THA in the Department of Joint Surgery at the Sixth Affiliated Hospital of Xinjiang Medical University from September 2020 to December 2022 were retrospectively selected based on inclusion criteria. They were divided into the DVT group (n = 65) and the non-DVT group (n = 397) according to the occurrence of postoperative DVT. The following variables were reviewed for both groups: age, sex, Body Mass Index (BMI), affected limb, previous history (smoking and drinking), diabetes, hypertension, operation time, total cholesterol, triglycerides, fibrinogen, hemoglobin, albumin, platelets, D-dimer, International Normalized Ratio (INR), and fibrin degradation products. Univariate analysis was conducted on these factors, and those with statistical significance were further analyzed using a binary logistic regression model to assess their correlation with DVT after THA. Results A total of 462 patients were included in the study, with the DVT group representing approximately 14% and the non-DVT group approximately 86%. The DVT group had an average age of 67.27 ± 4.10 years, while the non-DVT group had an average age of 66.72 ± 8.69 years. Univariate analysis revealed significant differences in diabetes mellitus, preoperative fibrinogen, preoperative D-dimer, preoperative INR, and preoperative and postoperative fibrin degradation products between the DVT and non-DVT groups. Binary logistic regression analysis identified diabetes mellitus, elevated preoperative fibrinogen, preoperative D-dimer, and preoperative INR (p
