Preoperative risk factors for postoperative cardiac arrest following primary total hip and knee arthroplasty: A large database study.

Background: Cardiac arrest (CA) has been identified as a potential complication following Total Hip Arthroplasty (THA) and Total Knee Arthroplasty (TKA). This retrospective, case-controlled study aims to identify risk factors in order to improve the management of patients undergoing THA or TKA with known preoperative comorbidities.

Methods: CPT codes were used to investigate the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database for patients who underwent THA or TKA from 2010 to 2017.
