Multimodal pain management strategies are critical in total knee arthroplasty (TKA). There has recently been a shift toward opioid sparing protocols, yet most publications continue to use narcotics in the perioperative period. Periarticular injections are a popular adjunct but studies regarding the optimal medications have high variability making it difficult to choose the optimal medication. ⋯ Although we saw trends for improvements in group LB, these were small and not clinically meaningful. It appears that both injections were effective. There is a significant cost difference and medications should be chosen based on surgeon preference and institutional needs.
