This article compares two nerve block combinations: Femoral Nerve Block (FNB) with Lateral Femoral Cutaneous Nerve Block (LFCNB), and Sciatic Nerve Block (SNB) with Saphenous Nerve Block via the Adductor Canal Block (ACB), evaluating anatomical targets, analgesic coverage and motor effects. №1 – FNB + LFCNB Good for anterior and lateral pain Doesn`t address posterior pain High fall risk due to quadriceps weakness №2 – SNB + ACB Comprehensive analgesia (anterior + posterior) Preserves quadriceps function Possible foot motor weakness if SNB too distal Evidence-Based Comparison SNB + ACB: Better early mobility, lower fall risk, more complete analgesia FNB + LFCNB: Higher motor impairment, limited coverage Overview of Each Nerve Block FNB: Anterior coverage LFCNB: Cutaneous only ACB: Medial/anterior knee SNB: Posterior knee coverageMethods In a retrospective study (May 1–June 1) 20 TKA patients were evaluated: 10 received FNB + LFCNB and 10 received SNB + ACB. Nineteen had spinal anesthesia; one had general. All blocks were given postoperatively. Patients receiving SNB + ACB experienced more comprehensive analgesia and better motor preservation, supporting its use in ERAS protocols.Results Use SNB + ACB for most modern TKA protocols Reserve FNB for specific cases where motor block is acceptable Tailor based on patient risk, surgical technique and institutional ERASConclusions Optimal nerve block choice boosts TKA recovery. The SNB + ACB combination offers effective, motorsparing analgesia, reduces fall risk and supports early rehabilitation, making it well-suited for modern ERAS protocols.",
