Effects of multi-site infiltration analgesia on pain management and early rehabilitation compared with femoral nerve or adductor canal block for patients undergoing total knee arthroplasty: a prospective randomized controlled trial

摘要

Purpose The aim of this study was to combine intra-articular and peri-articular with wound infiltration analgesia (multi-site infiltration analgesia, MIA) for patients undergoing total knee arthroplasty (TKA) and compare its pain management and early rehabilitation effect with the commonly used nerve block including adductor cannel block (FNB) and femoral nerve block (ACB).
