About this study
Official title: Randomized Control Trial Evaluating Postoperative Opioid Demands Following Hip Arthroscopy
This study will be a prospective, single-blinded, randomized controlled trial (RCT), investigating the influence of the number of opioid pills prescribed following primary hip arthroscopy. All patients who sign the consent form will be enrolled in the suited and randomized to one of the two treatment arms. The intervention group will receive 5 Norco pills, gabapentin (30 mg, once daily for 10 days following surgery), and Tylenol (1000 mg, three times daily for 10 days following surgery) while the control will receive the standard at our practice of 30 Norco pills.
Read the detailed description
Follow-up will take place at 1, 3, 6, and 12 months postoperatively. Variables of interest will include postoperative patient pain scores (i.e. Visual Analog Scale or VAS), total morphine equivalents taken in the first 30 days after discharge, number of unused opioid pills, opioid disposal rates, and standard patient reported outcomes measures (PROMs) including hip disability and osteoarthritis outcome score (HOOS), Harris Hip score (HHS), VAS for pain, international hip outcome tool (iHOT-12), and Hip outcome score (HOS).
For the purpose of this study, the investigators propose two standardized prescribing patterns across all teams. The first would be the control postoperative prescribing pattern and the second would be the experimental opioid reduced prescribing pattern. Patients will not be informed if their postoperative prescriptions are part of the control or opioid reduced prescribing pattern. Of note, patients will be allowed to cross over from the opioid reduced experimental group to the standard of care control group if they have breakthrough pain following surgery.
Timeline of Events:
- Following informed consent during the office visit when surgery is scheduled, all patients will be randomized to one of the postoperative pain management protocols, either the control or opioid reduced.
- Subjects will proceed with hip arthroscopy, including appropriate treatment and documentation of concomitant injuries.
- Over the course of the 1st month postoperatively, patients will complete a 30-day diary detailing which medications they took on each day and their daily average pain level (indicating whether physical therapy was performed). Data pertaining to prescription refills (I.e., number of refills, time to refill), number of left over pain medications, and disposal rates of opioid medications will also be recorded at these time points as well.
- Patients will return for standard of care postoperative visits at 1, 3, 6, and 12 months postoperatively. Patients will be asked to complete PROM questionnaires at the 3, 6, and 12 month follow-up time points

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Control Group RegimenOther
Norco (hydrocodone-acetaminophen) 5mg-325mg, 30 total pills. This is the standard of care prescribing procedure for pain management after hip arthroscopy.
Opioid reduced regimenOther
Tylenol extra strength (1000 mg, three times daily for 10 days following surgery), Gabapentin (300 mg at night for 10 days following surgery) and Norco (hydrocodone-acetaminophen) 5mg-325mg, 5 total pills
| Study group | Role | What they receive |
|---|---|---|
| Control Group | Placebo comparator | Control Group will receive the following pain medication regimen:
- Norco (hydrocodone-acetaminophen) 5mg-325mg, 30 total pills
The following non-opioid medications are standard of care at our practice following hip arthroscopy and, thus, will be prescribed to patients regardless of the group they are randomized to: aspirin (325 mg, two times daily for 30 days) and Indocin (75 mg extended release, one time daily for 10 days). Receives: Other: Control Group Regimen |
| Experimental Group - Opioid Reduced | Experimental | Experimental - opioid reduced: 50% less oxycodone relative to control group
* Tylenol extra strength (1000 mg, three times daily for 10 days following surgery)
* Gabapentin (300 mg at night for 10 days following surgery)
* Norco (hydrocodone-acetaminophen) 5mg-325mg, 5 total pills

What is being measured
The primary outcome is the main question the study is designed to answer.
Pain Score
Visual Analog Scale: unidimensional measure of pain intensity, which has been widely used in diverse adult populations. Score is determined by measuring the distance (mm) on the 10-cm line between the "no pain" anchor and the patient's mark, providing a range of scores from 0-100. A higher score indicates greater pain intensity.
Measured: 1 month postoperatively

Hip outcome score
questionnaire with a scoring system composed of 2 sub-scales. The Activities of Daily Living (ADL) sub-scale made of 19 items and a Sports sub-scale composed of 9 items. Both subscales are marked separately and 17 items from the Activities of daily living scale are scored from 0 to 4, with 0 being 'unable to do' and 4, 'no difficulty'. 'Not applicable' responses are also possible options. The total score is then multiplied by 4 to get the highest potential score which can be no greater than 68. An overall higher score from both of these sub-scales represents a greater level of function.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
This study will be a prospective, single-blinded, randomized controlled trial (RCT), investigating the influence of the number of opioid pills prescribed following primary hip arthroscopy. All patients who sign the consent form will be enrolled in the suited and randomized to one of the two treatment arms. The intervention group will receive 5 Norco pills, gabapentin (30 mg, once daily for 10 days following surgery), and Tylenol (1000 mg, three times daily for 10 days following surgery) while the control will receive the standard at our practice of 30 Norco pills.
Detailed description
Follow-up will take place at 1, 3, 6, and 12 months postoperatively. Variables of interest will include postoperative patient pain scores (i.e. Visual Analog Scale or VAS), total morphine equivalents taken in the first 30 days after discharge, number of unused opioid pills, opioid disposal rates, and standard patient reported outcomes measures (PROMs) including hip disability and osteoarthritis outcome score (HOOS), Harris Hip score (HHS), VAS for pain, international hip outcome tool (iHOT-12), and Hip outcome score (HOS).
For the purpose of this study, the investigators propose two standardized prescribing patterns across all teams.

Primary outcome
Pain Score
Time frame: 1 month postoperatively
Visual Analog Scale: unidimensional measure of pain intensity, which has been widely used in diverse adult populations. Score is determined by measuring the distance (mm) on the 10-cm line between the "no pain" anchor and the patient's mark, providing a range of scores from 0-100. A higher score indicates greater pain intensity.
