Condition: Total Knee Anthroplasty · Nerve Block · Ropivacaine · Sponsor: Huazhong University of Science and Technology
Effective postoperative pain management remains a cornerstone of enhanced recovery protocols following total knee arthroplasty (TKA). Inadequate analgesia not only compromises patient satisfaction but also impedes early mobilization and rehabilitation, thereby increasing the risk of perioperative complications. Current multimodal analgesic strategies frequently incorporate regional techniques, with the adductor canal block (ACB) and infiltration between the popliteal artery and capsule of the knee (IPACK) block emerging as established modalities that provide motor-sparing analgesia. Despite their widespread adoption, the optimal local anesthetic regimen for these blocks remains undefined. While liposomal bupivacaine has garnered interest for its extended duration of action, its clinical efficacy relative to conventional local anesthetics combined with perineural adjuncts remains a subject of ongoing debate. Specifically, perineural dexamethasone and dexmedetomidine have each demonstrated the capacity to prolong the analgesic duration of ropivacaine; however, direct comparative data among these three distinct strategies-liposomal bupivacaine alone versus ropivacaine supplemented with either adjunct-are notably limited. Given the absence of head-to-head randomized trials evaluating these three clinically viable techniques, the optimal approach to maximize analgesic duration while minimizing opioid-related adverse effects remains unclear. This study therefore aims to compare t…
