Liposomal Bupivacaine in Total Knee Arthroplasty

Analgesic Efficacy of Liposomal Bupivacaine in Total Knee Arthroplasty

Liposomal bupivacaine is a novel local anesthetic designed for prolonged pain relief. Despite its long-acting analgesic potential, liposomal bupivacaine is significantly more expensive than other local anesthetic alternatives. The primary aim of this investigation is to examine whether or not liposomal bupivacaine provides superior pain relief or clinically significant opioid-sparing effects versus a control to justify its cost.
