Comparison Of Venous Thromboembolism After Total Artificial Joint Replacement Between Musculoskeletal Tumors And Osteoarthritis Of The Knee By A Single Surgeon

The purpose of this study was to compare and evaluate the event of VTE (Venous Thromboembolism Event) after total artificial joint replacement between two groups diagnosed with either musculoskeletal tumors or osteoarthritis (OA) of the knee. From 2004 to 2014, a total of 1,402 patients (308 in tumor group, 1,094 in OA group) were involved in this study. The rate of asymptomatic DVT (Deep vein thrombosis) was significantly higher in tumor group when compared with OA group. Though both the incidence of symptomatic DVT and PE (Pulmonary embolism) were slightly higher in tumor group, no significant difference was detected. Tumor patients suffered an almost equal risk of VTE compared with OA patients except a higher rate of asymptomatic DVT after total artificial joint replacement. For patients with tumor, no significant association was observed between any potential risk factor and DVT.
