Detailed 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.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
pain control measure on pain scale of 1-10
Time Frame: 72 hours
|
to determine if liposomal bupivacaine provides superior pain control (decreased maximal pain control (decreased maximal pain scores) when compared to ropivacaine when injected in a periarticular injection.

Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
decreased maximal pain on pain scale of 1-10
Time Frame: 72 hours
|
