Patients will receive liposomal bupivacaine following simultaneous bilateral total knee arthroplasty.

Patients will receive liposomal bupivacaine following simultaneous bilateral total knee arthroplasty.
Liposomal bupivacaine: One (1) 20 mL vial of 266 mg liposomal bupivacaine (3% (~8mg free bupivacaine)) will be injected into each surgical (knee) site following simultaneous bilateral total knee arthroplasty. In addition, 30 mL of 0.25% bupivacaine (75 mg free bupivacaine) will be injected into each surgical (knee) site for a total of 83 mg free bupivacaine injected into each surgical (knee) site.

Blood samples will be drawn and analyzed to establish levels of bupivacaine detectable in the blood. Blood samples will be drawn at baseline (prior to injection), upon injection, at 15 minutes, 30 minutes, 1 hour, 2 hours, 4 hours, 8 hours, 12 hours, 24 hours, 48 hours, 72 hours post-injection and analyzed to determine levels of bupivacaine present.

Participants will receive Exparel (periarticular bupivicaine and liposomal bupivicaine).

Participants received Exparel (periarticular bupivicaine and liposomal bupivicaine).
periarticular bupivicaine and liposomal bupivicaine: Participants received Exparel (liposomal bupivacaine). Exparel is a FDA approved product. Exparel is an extended-release formulation of bupivacaine consisting of microscopic lipid-based particles that diffuse over an extended period. The result is pain relief that can last up to 96 hours after surgery. Extended-release liposomal bupivacaine-based analgesics were shown to provide extended pain relief and decrease opioid (pain medication) use. At the conclusion of the total joint arthroplasty procedure, Exparel was administered via injection into the joint (periarticular bupivicaine and liposomal bupivicaine).
