Electroacupuncture Spares Opioids for Knee Replacement Pain Relief

Patients who have electroacupuncture during total knee replacement surgery report less pain and need far fewer opioids to manage their discomfort. In the study, 65% of patients who received acupuncture during surgery were able to have a low-dose or opioid-free postoperative experience, compared to 9% of patients outside of the study.

The results of the study were presented at the ANESTHESIOLOGY® 2021 annual meeting

“Total knee replacements are one of the most common operative procedures in the United States and often very painful, so there’s a great need to explore non-opioid pain relief techniques for this type of surgery,” said lead author Stephanie Cheng, MD, DABMA, assistant attending anaesthesiologist at the Hospital for Special Surgery and assistant professor of clinical anaesthesiology at Weill Cornell Medicine. “Acupuncture is extremely safe and can help reduce pain with few unwanted side effects, but it has not been well researched as part of surgical anesthesia.”

The study enrolled 41 patients who had primary total knee replacement, all of whom received the institution’s standard opioid-sparing multimodal analgesic protocol, with the addition of electroacupuncture, which is a modified form of traditional acupuncture that applies a small electric current to thin needles that are inserted at known acupuncture points on the body. The acupuncture was administered during surgery by Dr Cheng, who is board-certified in medical acupuncture, to eight specific points in the ear to provide targeted pain relief in the knee.

With the addition of acupuncture, the majority of patients had reduced postoperative opioid use, compared to historical controls, while 65% of patients either maintained a low-dose opioid regimen of 15 oxycodone pills or less (57.5%) or remained completely opioid-free (7.5%) from induction of anaesthesia to 30 days post-surgery. Historically, only 9% of patients outside of the study were able to maintain a low-dose or opioid-free regimen post-surgery. Thirty days after surgery, all patients discontinued opioid use.

“Our study shows that if a trained medical acupuncturist is available to perform acupuncture in the operating room, it can help patients with postoperative pain recovery,” said Dr Cheng. “Most studies fail to incorporate nontraditional techniques, such as acupuncture, to help decrease the dependence on opioid medications for postoperative pain control.”

Low-dose perioperative opioid consumption is key to mitigating the opioid epidemic and opioid misuse by patients. Dr Cheng pointed out that with acupuncture being commonly used outside of the hospital as an effective therapy for pain management and treatment for a range of health issues and symptoms, it’s time to consider its benefits inside the hospital as well. “Additional research is needed to further define acupuncture’s effects and encourage its use in all aspects of disease treatment.”
