Exclusion criteria
Exclusion criteria: Simultaneous bilateral Total Knee Arthroplasty (the second surgical site is excluded) Patients in whom spinal anesthesia is not feasible or conversion to general anesthesia is anticipated Chronic opioid users Patients with central nervous system disorders or conditions that impair pain perception or expression Patients who are unlikely to cooperate with pain assessment during the study period Patients with known allergy or contraindication to local anesthetics (e.g., Ropivacaine) or Fentanyl Patients with severe peripheral neuropathy or neurological deficits Patients in whom nerve block is inappropriate due to bleeding disorders or uncontrolled anticoagulation therapy Patients with severe renal failure or hepatic failure Any other condition that, in the investigator’s judgment, makes the patient unsuitable for participation in the study
