Abstract
The number of annual THA's, TKA's, and TSA's is set to increase significantly by the year 2030, making it imperative to understand the risks for negative outcomes in these procedures. While research has studied the patient risk factors for perioperative and postoperative complications, there has been relatively little research for intraoperative complications. After a thorough literature review, the most supported finding was that patients with a BMI >30 had significantly more intraoperative blood loss than those with a BMI <30. All other relationships between patient risk factors and intraoperative complications of interest were inadequately studied.
•There has been little research comparing patient risk factors to intraoperative complications in primary THA, TKA, and TSA.•Most relationships between risk factors and intraoperative complications were inadequately studied, except for blood loss.•Patients with a BMI >30 had more intraoperative blood loss than those with a BMI <30.•Researchers should discriminate complications into discrete time categories including the intraoperative period.
