Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Hypothesis: Open-label Placebo (COLP) \< treatment as usual (TAU) control. Secondary Aims Analysis Plan: There are three secondary aims in this study.
Aim 1. To determine whether 6 weeks of Open-label Placebo (COLP) results in significantly reduced opioid consumption compared to treatment as usual. To test this aim, the investigators will conduct a t-test comparing mean opioid use over the 6 weeks of follow up. In secondary analyses, the investigators will adjust for any baseline factors including gender, age, symptom severity or type of surgery that could be a confounding variable.
1a. To determine if 6 weeks of Open-label Placebo (COLP) results in reduced opioid consumption compared to treatment as usual. Hypothesis: Open-label Placebo (COLP) \< treatment as usual (TAU) control.
Secondary Aims Analysis Plan: There are three secondary aims in this study.
Secondary Aim 1: Determine if there are significant differences in time to independence with physical therapy, length of stay, time to return to school, urinary retention, constipation, oxygen requirement, and number of contacts with medical team in Open-label Placebo (COLP) compared to treatment as usual (TAU).
Secondary Aim 2: Determine if there is an association between preoperative pain catastrophization, kinesiophobia, positive/negative affect, anxiety, and/or depression and response to Open-label Placebo (COLP) and/or treatment as usual (TAU).
Secondary Aim 3: Determine if there is an association between postoperative PROMIS scores, anxiety, and/or depression in open-label placebo (COLP) compared to treatment as usual (TAU).
Primary Objectives The primary objectives of this study are to: (1) to determine whether 6 weeks of conditioning with open-label placebo (COLP) results in reduced opioid consumption (amount and duration) compared to treatment as usual (TAU) control and (2) to determine whether 6 weeks of Open-label Placebo (COLP) compared to treatment as usual (TAU) results in different clinical outcomes.
Secondary Objectives
* To determine whether open-label placebo (COLP) affects anxiety and/or depression.
* To determine whether open-label placebo (COLP) affects length of stay, opioid side effects, time to independence with physical therapy, and/or number of contacts with medical team.
* To determine if there is an association between pain catastrophizing, kinesiophobia, and clinical outcomes.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Open-label Placebo (COLP)
Placebo will be supplied as a 330mg tablet (manufactured by Consolidated Midland Corporation). Each oral opioid dose is a 5mg Oxycodone tablet. Patients will take placebo with each oral opioid intake and 3 additional times per day beginning on POD 1. Investigator shall never prescribe ibuprofen. Investigator shall always prescribe Tylenol 625mg every 8hrs (PRN).

Treatment as usual
Each oral opioid dose is a 5mg Oxycodone tablet. Investigator shall never prescribe ibuprofen. Investigator shall always prescribe Tylenol 625mg every 8hrs (PRN).
Treatment As Usual (TAU)
Treatment As Usual (TAU) subjects will receive equal access to opioid and non-opioid analgesics. The preferred oral opioid dose is a 5mg Oxycodone pill. Subjects will take a placebo with each oral opioid dose and additional three times per day beginning on POD 1.
Treatment as usual
Each oral opioid dose is a 5mg Oxycodone tablet. Investigator shall never prescribe ibuprofen. Investigator shall always prescribe Tylenol 625mg every 8hrs (PRN).
