Research teams led by Javad Parvizi, MD, clinical research professor and vice chair of orthopedic surgery, have identified risk factors associated with two major postoperative issues for patients undergoing total hip or knee replacements.

Despite ongoing improvements in technology and perioperative protocols, some patients undergoing total joint arthroplasty (TJA) experience serious medical complications requiring postoperative intensive care. With TJA increasingly being performed in ambulatory surgical settings, it is important to understand which patients are most at risk for such complications. Dr. Parvizi and his colleagues conducted a study to identify patient risk factors for admission to an intensive care unit (ICU) following elective total hip (THA) and total knee (TKA) arthroplasty. The researchers used data on 12,342 THA patients and 10,976 TKA patients—132 and 114 of whom, respectively, had an unplanned postoperative ICU admission.
