A Comparison of Exparel Local Anesthetic in Total Knee Arthroplasty (TKA) Patients

August 8, 2017 updated by: Holy Cross Hospital, Florida

A Prospective Randomized Case Series Comparison on the Clinical Efficacy of Exparel Local Anesthetic in Total Knee Arthroplasty Patients

This is a prospective, single-center, single-blinded, randomized, case-control study. The study is conducted by a single investigator at an orthopedic surgery institute, with a minimum 6 week post operative follow-up period of TKA patients who receive Exparel compared with the surgeon's standard method (detailed below) for pain management intraoperatively.

Study Overview

Detailed Description

This is a prospective, single-center, single-blinded, randomized, case-control study. The study is conducted by a single investigator at an orthopedic surgery institute, with a minimum 6 week post operative follow-up period. Subjects scheduled for a planned total knee arthroplasty procedure will be consented and those meeting study criteria will be randomized to receive intra-operative injections at the surgical site of liposomal bupivicaine plus a multi-drug cocktail, or a multi-drug cocktail alone.

This study will recruit subjects on an ongoing basis with a minimum of 130 study participants and a maximum of 156. Efficacy data on surgical pain control and safety data will be collected at frequent intervals during the hospitalization. Each study participant will be followed for a minimum 6 week follow-up period.

Time Frame: VAS pain intensity scores will be collected starting four hours after end of surgery and every 4 hours thereafter until hour 24.
The area under the curve (AUC) of the VAS scores from 4-24 hours will be compared between the two treatment groups.
VAS pain intensity scores will be collected starting four hours after end of surgery and every 4 hours thereafter until hour 24.
Patient reported VAS pain intensity score. Post-surgery hours 24-48.
Time Frame: VAS pain intensity scores will be collected starting 24 hours after end of surgery and every 4 hours thereafter until hour 48, or discharge.
The AUC of the VAS scores from 24-48 hours or until discharge will be compared between the two treatment groups.
VAS pain intensity scores will be collected starting 24 hours after end of surgery and every 4 hours thereafter until hour 48, or discharge.
Patient reported VAS pain intensity score. Post-surgery hours 48-72.
Time Frame: VAS pain intensity scores will be collected starting 48 hours after end of surgery and every 4 hours thereafter until hour 72, or discharge.
The AUC of the VAS scores from 48-72 hours or until discharge will be compared between the two treatment groups.
VAS pain intensity scores will be collected starting 48 hours after end of surgery and every 4 hours thereafter until hour 72, or discharge.
