0.25% Bupivacaine Versus a Mixture of 0.25% Bupivacaine & 1.3 % Liposomal

Status Terminated

Clinical Trial Summary

Total knee and hip replacements are some of the most common orthopedic procedures that require aggressive postoperative pain management. This management helps us to improve clinical outcomes such as participation in early physical therapy, hospital discharge, and patient satisfaction. Based on the recent anatomical evidence and the investigator's knowledge of the complexity of the knee joint innervation the investigator proposes a new regional anesthesia technique that provides a complete sensory blockade and better analgesia while preserving the quadriceps strength and avoiding the potential for foot drop caused by inadvertent blockade of the common peroneal nerve.

Clinical Trial Description

This is an assessor-blinded randomized controlled trial evaluating the efficacy of liposomal bupivacaine (Exparel) in patients undergoing Total Knee Arthroplasty. The primary outcome of this study is the proportion of patients "fit to discharge" on postoperative day one. Recently, liposomal bupivacaine (LB) (Exparel) was introduced into clinical practice, using a lipid-based depot (DepoFoam) technology for sustained release of bupivacaine. LB (Exparel) uses this technology to extend the delivery of bupivacaine, a local anesthetic that has been used in clinical practice for decades for peripheral nerve block, spinal, and epidural analgesia and anesthesia. This formulation prolongs the duration of analgesia of bupivacaine for up to 72 hours with a single injection. The study was designed to compare two of our current standard therapies:

1. Adductor Canal Block + Tissue Infiltration (lateral, medial and femoral compartment + posterior capsule tissue infiltration using 0.25% bupivacaine; and

2. Adductor Canal Block + Tissue Infiltration (lateral, medial and femoral compartment + posterior capsule tissue infiltration) using 1:1 mixture of 1.3% LB (Exparel) + 0.5% bupivacaine HCl mixture. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
