Key clinical point: Postoperative complications after total knee arthroplasty differ between morbidly obese patients and those who have had bariatric surgery.
Major finding: In total knee arthroplasty procedures, a bariatric surgery group fared better than a morbidly obese group in pulmonary embolisms (odds ratio, 0.22) but worse in blood transfusions (OR, 1.76).
Study details: Retrospective analysis of 2006-2014 U.S. data of 9,803 matched patients who underwent total knee arthroplasty (bariatric surgery vs. morbidly obese).
Disclosures: The study was supported by various funders including the National Natural Science Foundation of China, the Natural Science Foundation of Guangdong Province, the Project of Administration of Traditional Chinese Medicine of Guangdong Province and others.
