Abstract

PURPOSE: To thoroughly evaluate preoperative risk factors for deep venous thrombosis (DVT) in patients with knee rheumatoid arthritis (RA) undergoing unilateral total knee arthroplasty (TKA). METHODS: Clinical data of 106 patients with knee RA who underwent unilateral TKA from August 2014 to October 2020 were collected. All patients received ultrasonic examination of the veins of both lower extremities on the third day after TKA and were divided into DVT and non-DVT groups. The associations between age, gender, body mass index (BMI), history of diabetes/hypertension, common serum lipid levels, indicators related to coagulation function, blood viscosity, erythrocyte sedimentation rate (ESR) and postoperative DVT were statistically compared and analyzed. RESULTS: ESR was significantly correlated with DVT risk after TKA (OR = 1.844, 95% CI = 1.022–2.981, P = 0.019). Receiver operating characteristic (ROC) curve analysis showed the optimal cut-off point of ESR for predicting DVT was 42 mm/h with a sensitivity of 95.5% and specificity of 66.7% . CONCLUSION: An increased preoperative ESR value is a risk factor for DVT in patients with knee RA following unilateral TKA. Pre-surgery control of ESR level and prevention of postoperative DVT in these patients are worthy of attention.
