Vakharia RM, et al. - Researchers assessed whether there exist higher rates of venous thromboembolisms (VTEs), readmission, and costs of care in patients who have rheumatoid arthritis (RA) undergoing primary total knee arthroplasty (TKA). They used a nationwide claims database, to select patients who have RA undergoing primary TKA, and these cases were matched to controls in a 1:5 ratio by age, gender, and comorbidities. Findings revealed that the rates of VTEs, readmissions, and costs were significantly higher in patients who have RA undergoing primary TKA, this was observed after adjusting for age, gender, and comorbidities. Since there is a continuously rising prevalence of RA within the United States, the findings can be employed to sufficiently counsel and teach these patients about this adverse event after their procedure.
