The United States is in the midst of an ongoing opioid crisis. In 2019, approximately 153 million opioid prescriptions were dispensed (46.7 per 100 persons) and 50,000 people died from opioid-involved overdoses. Orthopaedic and spine conditions account for 27.7% of opioid prescriptions and prior studies demonstrate that musculoskeletal pain is frequently reported by opioid abusers as their initial reason for consuming opioids. For these reasons, orthopaedic surgeons are uniquely posed to combat this crisis. Multimodal pain control is a strategy that utilizes multiple pain medications to provide analgesia. The theory behind this strategy is that agents with different mechanisms of action work synergistically to reduce pain by blocking multiple pain pathways. Several randomized controlled trials have investigated the efficacy of multimodal pain control for orthopaedic procedures, including anterior cruciate ligament reconstruction, labral repair, meniscus repair, and rotator cuff repair. In these studies, patients who received a multimodal nonopioid regimen had equivalent or better postoperative pain control compared to a standard opioid regimen. Furthermore, no severe side effects were reported in patients who received the multimodal nonopioid regimen. This randomized, single blinded, standard of care-controlled clinical trial aims to investigate the efficacy of a multimodal pain control (similar to the regimen utilized in the aforementioned studies) for controlling pain following shoulder arthroplasty. Adult patients indicated for anatomic or reverse total shoulder arthroplasty will be randomized to either the experimental or comparison group. The experimental group will receive a multimodal, non-narcotic pain control regimen consisting of Celecoxib, Pregabalin, and Tramadol preoperatively; Dexamethasone, Acetaminophen, Ropivacaine, Epinephrine, and Ketorolac intraoperatively; and Dexamethasone, Pregabalin, Tizanidine, Magnesium, Ibuprofen, and Acetaminophen postoperatively. In addition to the aforementioned multimodal pain control regimen, the comparison group will receive a standard prescription of Oxycodone to be taken as needed postoperatively. If patients in the experimental group feel their pain is uncontrolled, they have the option of calling in to request a prescription of Oxycodone. Pain, pain medication use, and medication side effects will be closely monitored for the first 10 days after surgery by having patients respond to daily automated text messages. Additionally, all study participants will complete patient-reported outcome measures (PROMs) surveys and undergo physical examination of their shoulder during routine clinic visits preoperatively and at 1 week, 6 weeks, 3 months, 6 months, 1 year, and 2 years postoperatively. The primary outcome of this study is postoperative pain scores on the Numerical Rating Scale (NRS) for the first 10 days postoperatively. We hypothesize that there will be no significant difference between the groups with regard to the primary outcome. Secondary outcomes measured during the first 10 days postoperative include morphine milligram equivalents (MMEs) of opioids consumed, Patient-Reported Outcome Measurement Information System Pain Interference (PROMIS-PI) score at first postoperative clinic visit (7-10 days postoperatively), duration of patient reported adverse events (ie, constipation, nausea, diarrhea, upset stomach, drowsiness, loopiness), perioperative complications, and satisfaction with pain control. Secondary outcomes measured at routine postoperative clinic visits out to 2 years after surgery include postoperative complications, need for revision surgery, PROM scores (ie, PROMIS upper extremity, PROMIS PI, PROMIS D, American Shoulder and Elbow Surgeons Shoulder Score, Shoulder Arthroplasty Smart, Constant-Murley), hospital and emergency department readmission (30-day, 60-day, 90-day), duration of narcotic pain medication use shoulder strength, and shoulder range of motion.
