Summary

This trial is comparing opioid usage after knee surgery for those given a new medication vs. those given usual care.

Who is the study for?
This trial is for adults aged 35-70 with primary osteoarthritis planning a total knee replacement. Eligible participants must have a BMI under 40, be discharged the same day as surgery, and have certain limits on knee deformity. Exclusions include inflammatory arthritis, kidney disease, uncontrolled diabetes, liver disease, mental health disorders, allergies to specific drugs including NSAIDs and local anesthetics, prior significant knee surgeries or conditions that affect walking.
What is being tested?
The study tests Zynrelef (a bupivacaine-meloxicam injectable solution) for pain management after total knee replacement surgery. It aims to see if Zynrelef can control pain better and reduce opioid use compared to standard care in the days following surgery. Participants are randomly assigned to receive either Zynrelef or usual postoperative care.
What are the potential side effects?
Potential side effects of Zynrelef may include reactions at the injection site such as redness or swelling, nausea or vomiting due to anesthesia-related effects; headache; itching; fever; back pain; constipation from opioids taken for breakthrough pain; dizziness and sleep disturbances.
