Brief summary

The purpose of this study is to evaluate whether liposomal bupivacaine is superior to normal bupivacaine in terms of providing better pain control postoperatively after total knee arthroplasty.

Inclusion criteria

Willing and able to sign an informed consent.

Exclusion criteria

1. Patients unwilling or unable to consent to participate in the study. 2. Prisoners. 3. Pregnancy. 4. Reported to have mental illness or belonging to a vulnerable population. 5. Subject is \< 18 years of age. 6. Patients receiving general anesthesia for the total knee arthroplasty. 7. Subject has impaired decision-making capacity per discretion of the Investigator. 8. Any condition for which the primary anesthesia care team deems neuraxial anesthesia inappropriate. 9. Significant pre-existing neuropathy on the operative limb. 10. Significant chronic pain disorders (i.e. fibromyalgia, complex regional pain syndrome I & II, among others). 11. Subject has sustained a significant trauma to the operative knee. 12. Chronic Opioid Use (daily or almost daily use of opioids for \> 3 months). 13. Known hypersensitivity and/or allergies to local anesthetics. 14.

Design outcomes

Primary

MeasureTime frameDescription
Opioid UseUp to 2 weeksOpioid use after SoC TKA surgery will be evaluated as morphine milligram equivalents

Secondary

MeasureTime frameDescription
Length of hospitalizationUp to 5 daysNumber of days of hospitalization after elective admission for TKA surgery
Incidence of events of PONVUp to 5 daysIncidence of post-operative nausea and vomiting (PONV) will be reported throughout the duration of hospitalization
Number of participants requiring narcotic prescriptions2 weeksThe number of participants that require further narcotic prescriptions will be reported
Distance Ambulated with physical therapistUp to 5 daysAverage daily distance ambulated using the 6 minute walk test
Post-Operative Pain ScoreUp to 5 daysPost-Operative Pain will be measured via a self-reported Visual Analog Scale (VAS) score. The VAS Pain score ranges from 1-10 with 1 being free of pain and 10 being the most pain.
Patient Satisfaction as per the Knee Society ScoreUp to Week 6The Knee society score has a total score ranging from 100-0. Scores between 100 and 85 points are considered excellent results, scores between 84 and 70 points are considered good results. Scores between 69 and 60 points are considered fair, and scores less than 60 are considered poor results
Incidence of urinary retention from narcotic use2 WeeksIncidence of urinary retention from narcotic use will be measured via the need for urethral catheterization.
