Patients will be prescribed the current department-wide postoperative pain protocol as described in the Intervention Description.

Multimodal pain regimen medications will be prescribed and administered preoperatively in preoperative holding area, intraoperatively during the procedure, and postoperatively as described in the Intervention Description.

Preoperatively: One dose of Pregabalin 100mg and Celecoxib 400mg along with interscalene block

Intraoperatively: Intravenous Dexamethasone 0.1mg/kg (maximum dose of 8mg), Magnesium 2g, Acetaminophen 1000mg, and local infiltration of 0.5% Ropivacaine 20ml

Postoperatively (Discharge): Acetaminophen 975mg every 4 hours, Meloxicam 7.5mg once per day, Pregabalin 50mg twice per day, Magnesium 400mg once per day, along with rescue Oxycodone 5mg every 4 hours, as needed

Post-operative narcotics usage will be assessed by the number of oxycodone tablets used in the first week (7 days) after surgery. The week's use will be accounted by counting the left-over oxycodone tablets brought in by the patients. In addition, the electronic medical record will be checked to ensure that no extra narcotics were called in. Results will be summarized by study arm using means and standard deviations.

A pain score will be determined using the VAS, a unidimensional measure of pain intensity. Patients will be asked to rate and record pain intensity daily during the study. The VAS score at post-operative day 7 will be reported. The VAS 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, such that higher scores are indicative of greater pain intensity. Results will be summarized by study arm using basic descriptive statistics.
