Study Finds Non-Opioid Pain Relievers Effective for Arthroscopic Surgery

Patients recovering from minimally invasive shoulder or knee surgery do just as well with non-opioid pain relievers as those who use opioids, according to a new study at McMaster University and Hamilton Health Sciences (HHS) in Canada.
The study, published by the Journal of the American Medical Association (JAMA), looked at 193 outpatients who had arthroscopic surgeries on their knees or shoulders at three hospitals in Hamilton, Ontario.
About half received standard care with opioids for postoperative pain, while the other half received naproxen and acetaminophen for pain, as well as pantoprazole, a medication normally used to treat heartburn and acid reflux. An emergency supply of opioids was available to both groups, if needed, for additional pain relief.
After six weeks, patients in the opioid group had used an average of 72.6 mg of opioids, compared to 8.4 mg in the opioid-sparing group. Two patients in the opioid-sparing group asked for opioid medication after discharge. Researchers say there were no significant differences in pain levels, patient satisfaction or adverse events between the two groups.
“This study clearly shows that many of these surgical patients can be treated safely without opioid medications in a select population,” said lead author Olufemi Ayeni, MD, a professor of surgery at McMaster and an orthopedic surgeon at HHS. “Furthermore, by reducing the number of opioids prescribed, we can collectively reduce the development of a reservoir of unused medications that can cause harm to many in society.”
Over the past decade, the number of arthroscopic surgeries has soared in North America. About one million arthroscopies are performed annually in the United States and 100,000 in Canada. Several studies, however, have that found arthroscopic surgeries provide only temporary relief from knee pain and do not improve function long term.
To be clear, there is no comparison between arthroscopies and highly invasive surgical procedures such as heart bypass surgery. Arthroscopies are a type of “keyhole” surgery in which the surgeon makes a small incision and inserts a tiny camera and instruments to diagnose and repair damaged ligaments or joints. The procedure often takes less than an hour and patients are sent home the same day — so there is less need for pain medication.
A recent analysis of nearly half a million minimally invasive surgeries in the U.S. found that the number of opioid pills prescribed to patients fell by 50% since 2017. Hospitals are increasingly using acetaminophen, non-steroidal anti-inflammatory drugs (NSAIDs), gabapentinoids and other non-opioids for post-operative pain.
Most Americans are more worried about treating post-operative pain than they are about becoming addicted to opioids. A 2021 Harris poll found that nearly 8 out of 10 U.S. adults believe opioids are sometimes necessary to manage pain after surgery and 60% prefer opioids over OTC pain relievers.
