Research Article: Systemic Ropivacaine Concentrations Following Local Infiltration Analgesia and Femoral Nerve Block in Older Patients Undergoing Total Knee Arthroplasty
Introduction:
Regional anesthetic techniques have been shown to significantly improve patient satisfaction and reduce postoperative complications after total knee arthroplasty (TKA). – While femoral nerve block (FNB) provides excellent analgesia and requires less local anesthetic compared to periarticular infiltration, it is associated with quadriceps weakness that may lead to falls. Local infiltration analgesia (LIA) has the advantage of preserving motor power, but the impact of a large absorption surface in the postoperative…
