• BACKGROUND
    • In patients who require bilateral total hip arthroplasty (THA) or total knee arthroplasty (TKA), staged procedures are a reasonable option for treatment of bilateral osteoarthritis. We sought to determine whether perioperative outcomes differed between first and second total joint arthroplasty (TJA).
  • METHODS
    • This was a retrospective review of all patients who underwent staged, bilateral THA or TKA between January 30, 2017, and April 8, 2021. All patients who were included underwent their second procedure within 1 year of the first. Patients were separated based on whether both their procedures took place before or subsequently after an institution-wide opioid-sparing protocol that was implemented on October 1, 2018. A total of 961 patients who underwent 1,922 procedures met the inclusion criteria for this study. For THA, 388 unique patients comprised 776 procedures, while 573 unique patients comprised 1,146 TKAs. Opioid prescriptions were prospectively documented on nursing opioid administration flowsheets and converted to morphine milligram equivalents (MME) for comparison. Activity measure scores for postacute care (AM-PAC) were used as a measurement of physical therapy progression.
  • RESULTS
    • Hospital stays, home discharges, perioperative opioid usages, pain scores, and AM-PAC scores were not significantly different for the second THA or TKA compared to first procedure, regardless of timing in relation to the opioid-sparing protocol.
  • CONCLUSION
    • Patients experienced similar outcomes following their first versus their second TJA. Limited opioid prescriptions following TJA do not negatively impact pain and functional outcomes. These protocols can safely be instituted to help mitigate the opioid epidemic.
