Application of Genicular Nerves Block Combined with iPACK Block in Postoperative Analgesia of Total Knee Arthroplasty

Abstract

The incidence of moderate to severe pain after total knee arthroplasty (TKA) ranges from 30-60% [1]. In the context of enhanced recovery after surgery, multimodal analgesia with peripheral nerve block as the core has become the main method of postoperative analgesia after TKA, and good analgesia is conducive to the early recovery of patients. Genicular nerve block (GNB) provides good analgesia anterior to the knee, while infiltration between the popliteal artery and capsule of the knee (iPACK) block provides good analgesia posterior to the knee [2]. We report a case of genicular nerve block combined with iPACK block for postoperative analgesia after total knee arthroplasty.
