Surgeon-Performed High-Dose Bupivacaine Periarticular Injection With Intra-Articular Saphenous Nerve Block Is Not Inferior to Adductor Canal Block in Total Knee Arthroplasty

摘要

Background: Periarticular injection or anesthesiologist-performed adductor canal block are commonly used for pain management after total knee arthroplasty. A surgeon-performed, intra-articular saphenous nerve block has been recently described. There is insufficient data comparing the efficacy and safety of these methods.
