At this time, no formal ERAS (enhanced recovery after surgery) protocol exists for THR that incorporates perioperative acupuncture. Developing, and more importantly, validating a preliminary fast-track protocol for THR can have a significant impact on reducing recovery time and improving the rate at which this subgroup of surgeries is done on an outpatient basis. Furthermore, previous studies of acupuncture as an adjunctive therapy for postoperative analgesia have primarily investigated patient satisfaction rather than the impact on postoperative opioid consumption.
The majority of studies also place acupuncture needles preoperatively, rather than following induction of anesthesia (intra-operatively). This study hopes to show that placing auricular therapy needles intraoperatively is a feasible part of a protocol for motivated patients to minimize opioids after total knee arthroplasty. The prospect of incorporating intraoperative acupuncture as an adjunct into said protocol is very attractive given its low cost, its safety profile, its ease of administration, and the growing evidence supporting its efficacy. This study would provide further clarity on whether perioperative acupuncture can effectively reduce hospital length of stay and post-operative opioid consumption, in addition to evaluating the role of perioperative acupuncture in improving recovery after THR as part of a multimodal fast-track protocol.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Active Acupuncture Group | Active Comparator | For the patients randomized to the acupuncture group, once sedation has been deemed adequate by the anesthesiologist, a certified medical acupuncturist will perform ipsilateral Auricular Trauma Protocol (ATP) acupuncture at eight ear points (Hypothalamus, Amygdala, Hippocampus, Prefrontal Cortex, Point Zero, Shen Men, Insula, Vagus) with 30Hz electrostimulation at two of those points (Shen Men and Hypothalamus). Acupuncture needles will be left in place and stimulated for 60 min and then removed. |
|
| Placebo No Acupuncture Group | Placebo Comparator | These patients will not receive acupuncture treatment during surgery, their surgery will continue as normal. |
|
| Name | Type | Description | Arm Group Labels | Other Names |
|---|---|---|---|---|
| Auricular Trauma Protocol (ATP) Acupuncture | Device | Small filiform (needle) like needles use low frequency electrostimulation at eight ear points for 60 minutes while patient is sedated during surgery. All other aspects of the surgical procedure will go as planned according to the hospital's standard of care. |
| Measure | Description | Time Frame |
|---|---|---|
| Opioid Usage | The primary outcome is the incidence of patients who maintain a low-dose opioid regimen (71.5 OME or less) out to 30 days post-op. Patient intake of opioid medication will be measured up to the 30 days post-operation. | Day 30 |
| Measure | Description | Time Frame |
|---|---|---|
| NRS Pain Scores | NRS pain scores at rest and with movement | Post-operatively in: PACU (post-anesthesia care unit) immediately post-operation, Day 1, Day 2, Day 14 & Day 30 |
| Satisfaction with Protocol |

Subjects were randomly assigned to receive Acupuncture, or No Acupuncture based on a 1:1 schedule with blocks of four created prior to study initiation using SAS version 9.4 (SAS Institute; Cary, NC) by a member of the biostatistics core not otherwise involved in the trial.
Treatment assignments were transcribed onto notecards and sealed in opaque, consecutively numbered envelopes by a research assistant not otherwise involved in the trial.
After patient consent and prior to anesthesia start, the research assistant involved in the trial handed the randomization envelope to the medical acupuncturist. All patients and research assistants involved with data collection will be blinded to the group allocation.
Randomization lists will be accessed by an intra-op monitor RA who is not otherwise involved in the study in any other aspect.

|
| No Acupuncture Group | Other | This involves not receiving the acupuncture treatment and surgery going entirely as normal according to the hospital's standard of care. |
|
Satisfaction with the whole protocol/study experience and pain management throughout surgery and recovery. Patients will be asked to rate their satisfaction with the study, care provided and pain management on a scale of 1-10 with 1 being least satisfied and 10 being most satisfied.
| Day 30 |
| Post-operative Nausea & Vomiting (PONV) | Incidence of nausea, vomiting, pruritus, constipation | Post-operatively in: PACU (post-anesthesia care unit), Day 1 |
| Range of Motion | Postoperative range of motion (extension and flexion) | Post-operatively on: Day 1 and Day 14 |
| Pain Catastrophizing Scale (PCS) | 13-item self-report measure designed to assess catastrophic thinking related to pain among adults with or without chronic pain. It is a self-reported measure with items scored from 0-4 with 4 being the most catastrophic. The higher a patient's total scores the more catastrophic their thoughts are in relation to pain. | Pre-operative |
| Center for Epidemiologic Studies Short Depression Scale & Anxiety Scale (CES-D) | 20 questions that asks about various symptoms of depression as they have occurred in the past week. Response options range from 0 to 3 for each item (0 = Rarely or None of the Time, 1 = Some or Little of the Time, 2 = Moderately or Much of the time, 3 = Most or Almost All the Time). Total scores range from 0 to 60, with higher scores indicated greater depressive symptoms. | Pre-operative |
| Hours to Discharge | The total number of hours patients spend in the hospital until discharge from the hospital. This will be measured from the start of surgery in the OR until discharge from hospital. | Will be assessed up to 4 days post-operatively or until patient leaves hospital. |
