NCT05188053

Brief Summary

The purpose of this study is to compare an FDA-approved medication for post-operative pain control (HTX-011) to the standard of care institutional practice for periarticular analgesia after primary total knee arthroplasty (weight based dosing of Ropivacaine, epinephrine and ketorolac diluted with saline). We are doing this research study to find out if this new medication provides superior pain control within 72 hours following surgery.

Outcome Measures

Primary Outcomes (1)

  • Pain Control at 72 Hours Postoperatively

    Area Under the Curve (AUC) of the graph for mean Numerical Rated Score (NRS) for pain (0-10) over time (0-72 hours) / NRS AUC 0-72. Pain scores were collected by patient self-report 15 times over the 72 hours after surgery, and averaged amongst the patients for each study arm. Lower values represent better pain control based on lower mean 0-10 pain scores over the 72 hour period after surgery. The minimum value is 0, meaning patients reported 0 pain on a 0-10 scale at all 15 time points within 72 hours. The maximum value would be 720, meaning patients reported a 10 for pain on a 0-10 scale at all 15 time points within 72 hours.

    48-hours postoperative total knee arthroplasty

  • Opioid Consumption 72 Hours Postoperatively
