Summary
The objective of the study is to compare the efficacy of adductor canal blocks versus periarticular bupivacaine injections for pain management in total knee arthroplasty. This randomized clinical trial will compare outcomes between adductor canal blocks, periarticular bupivacaine injections, and periarticular liposomal bupivacaine injections. Results from this study will help determine the most appropriate perioperative pain management strategy for patients undergoing a total knee arthroplasty.
