Study Evaluates VTE Rates in Revision Joint Arthroplasty
Rates of venous thromboembolism (VTE) among revision total knee arthroplasty (rTKA) and revision total hip arthroplasty (rTHA) patients did not change between 2008 and 2016, according to a study published online in The Journal of Arthroplasty. The National Surgical Quality Improvement Program database provided information on 30,406 patients who underwent rTKA and rTHA between 2008 and 2016. Researchers evaluated 30-day incidences of VTE, deep vein thrombosis (DVT), pulmonary embolism (PE), and mortality for each year. Among rTKA patients, the overall incidences of 30-day VTE, DVT, PE, and mortality were 1.2 percent, 0.9 percent, 0.4 percent, and 0.5 percent, respectively. In bivariate analysis, there was no significant change in any of the four outcomes over the eight years studied. For rTHA, 30-day incidences of VTE, DVT, PE, and mortality were 1.0 percent, 0.7 percent, 0.4 percent, and 0.7 percent, respectively; there were no significant changes in these over the study period, but the rate of mortality significantly decreased.
