Study Summary

To help curb the use of opioid medications following orthopedic surgery investigators have developed a new multi-modal pain pathway. Investigators aim to compare this regimen with and without the inclusion of opioid medications. This study will be performed in a randomized, double-blinded, placebo-controlled fashion in patients undergoing primary total knee or total hip arthroplasty. Investigators hypothesize that the opioid devoid pathway will show equivalent pain scores to the pathway that includes opioids while also having less constipation, nausea, and vomiting following surgery. If successful, this would create a dramatic decrease in opioid consumption following orthopedic surgery while still providing appropriate pain relief to patients.

Primary Outcome

compare the postoperative pain levels both in the hospital setting as well as daily for two weeks following discharge between patients in the opioid treatment group and those in the non-opioid treatment group. This will be performed with clinical exams while in the hospital and with phone surveys on discharge. Results will be recorded using the Visual Analog Scale for pain scores. This scale ranges from 0 to 10, with zero being no pain and 10 being as bad as can be, and includes visual facial cu
