NCT04917055

Brief Summary

Comparing the pain control outcomes for patients undergoing total knee arthroplasty (TKA) with either: 1) adductor canal single shot injection plus placebo iPACK injection or 2) adductor canal single shot injection plus bupivacaine and dexamethasone iPACK injection. There are two surgical approaches for TKA 1) open 2) ROSA robotic assisted. Both follow the same pain management pathway. We plan to enroll patient undergoing either surgical procedure.
