Opioid-Free Perioperative Pain Protocol Is Noninferior to Opioid-Containing Management .
This study has been identified as potentially high impact.
OE's AI-driven High Impact metric estimates the influence a paper is likely to have by integrating signals from both the journal in which it is published and the scientific content of the article itself.
Developed using state-of-the-art natural language processing, the OE High Impact model more accurately predicts a study's future citation performance than journal impact factor alone.
This enables earlier recognition of clinically meaningful research and helps readers focus on articles most likely to shape future practice.
An Opioid-Free Perioperative Pain Protocol Is Noninferior to Opioid-Containing Management: A Randomized Controlled Trial.
J Bone Joint Surg Am. 2025 Apr 2;107(7):665-677.Three hundred fifteen patients undergoing five common elective orthopedic procedures were randomized to receive either an opioid-free perioperative pain management protocol (n=157) or an opioid-containing protocol (n=158). The primary outcome was the numeric rating scale (NRS) for pain at 24 hours postoperatively. Secondary outcomes included pain levels at other time points (6 and 12 hours; 2 weeks, 6 weeks, and 1 year), comfort, opioid consumption, patient-reported outcomes, and adverse events. Outcomes were assessed up to 1 year post-surgery. Overall, the results revealed that the opioid-free protocol was noninferior to the opioid-containing protocol for pain at 24 hours. Pain levels were significantly lower in the opioid-free group at 12 hours and 2 weeks. The opioid-free group also reported better comfort at 24 hours and greater satisfaction with pain control at 6 weeks. No significant differences in adverse events or readmissions were observed. These findings suggest that an opioid-free protocol can safely and effectively manage pain in the perioperative setting for orthopedic procedures.
