The intervention group will receive spinal anesthesia followed by BiFeS block and adductor canal block before surgery, in addition to standard multimodal analgesia and postoperative morphine patient-controlled analgesia (PCA). The control group will receive spinal anesthesia and standard multimodal analgesia with postoperative morphine PCA without peripheral nerve block.\n\nThe primary outcome is total morphine consumption during the first 24 postoperative hours. Secondary outcomes include postoperative pain scores assessed by Numeric Rating Scale (NRS), time to first analgesic requirement, time to first foot movement, and Quality of Recovery-15 (QoR-15) scores.",[29,30],"Postoperative Pain Following Knee Arthroplasty","Total Knee Arthroplasty",[32,33,34],"Postoperative Pain","BiFeS","BiFeS and Adductor Canal Block","RECRUITING","2026-06-10",{"date":38,"type":39},"2026-06-12","ACTUAL",{"date":41,"type":39},"2026-06-02",{"date":43,"type":23},"2027-07-02",{"name":45,"class":46},"Ömer Kayar","OTHER_GOV",""]
