Myocardial Infarction Risk in Arthroplasty vs Arthroscopy: How Much Does Procedure Type Matter?

After controlling for patient characteristics and comorbidities, TJA increased the short-term risk of serious cardiac event compared to a less-invasive procedure. This information better quantifies the risk differential for patients considering surgery as they engage in shared decision making with their providers. In addition, our data may have an impact on perioperative management of antithrombotic medications used in patients with cardiac disease. The median time in days to serious cardiac event was 2 in THA and 3 in TKA vs 4 in KA, which may have implications in postoperative monitoring of patients after surgery.
