Background: This study aimed at assessing short-term risk of serious cardiac events after elective total joint arthroplasty (TJA) as compared to a less-invasive procedure, knee arthroscopy (KA).
Methods: Patients who underwent elective primary total hip arthroplasty (THA), total knee arthroplasty (TKA), or KA from 2011 to 2014 were identified in the American College of Surgeons National Surgical Quality Improvement Program database. A 1:1 propensity matching was used to generate 2 control cohorts of KA patients with similar characteristics.
