Comparison of Comparison of Ropivacaine & Liposomal Bupivacaine for Total

Status Withdrawn

Clinical Trial Summary

This is a randomized prospective outcomes study comparing two groups of patients. One group will receive liposomal bupivacaine for a periarticular injection. The other will receive ropivacaine for periarticular injection for pain relief after Total Knee Arthroplasty. the primary objective of this study is to determine if liposomal bupivacaine provides superior pain control (decreased maximal pain scores within the first 72 hours post surgery) when compared to ropivacaine when injected in a periarticular injection.

Clinical Trial Description

The current standard of care at our institution for pain relief in Total Knee Arthroplasty is ropivacaine injectate into the knee for acute postoperative pain relief. This provides pain relief for a duration of 6-18 hours after surgery. All patients in this study will also receive multimodal analgesia following surgery in both arms of the study. This will be the first study to prospectively analyze these two regimens.

Study group 1 (ropivacaine arm) consist of 100 mL (1 mL ketorolac, 2.5 mL morphine, 28.95 mL normal saline, 300 mcg of epinephrine, and 200 mg ropivacaine) Study group 2 will consist of 100 mL (one syringe with 50 mL total: 40 mL 0.25% bupivacaine, 300 mcg epinephrine, 1 mL ketorolac, 2.5 mL morphine, 6.5 mL normal saline) (one syringe with 50 mL total: 20 mL liposomal bupivacaine 30 mL normal saline). The periarticular injection will occur at the end of the procedure. Adequate analgesia will be defined as < 3 VAS at rest and if VAS is greater that 3 adjustments in oral or intravenous pain medications. Postoperatively the study team will evaluate for any signs of complications. Pain scores and opioid usage will be recorded daily while the subject is in the hospital. A quality of recovery survey will be completed at 72 hours post injection. All subjects will be contacted by phone at day 14 to determine if there have been any adverse events and report their pain level. ;

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.
