Gabbard MD, et al. - Researchers retrospectively analyzed 6996 patients who underwent elective primary arthroplasty (2453 hip, 4543 knee) to examine the predictive value of pre-operative Emergency Department (ED) visits for post-operative ED visits following elective total knee and total hip arthroplasty (TKA and THA). observations suggest that prior to total joint arthroplasty, presentation to the ED is common and is predictive of a postoperative visit within 90 days. Patients’ risk of a postoperative visit within 90 days further increases with increasing preoperative visit frequency.
