"The Effect of Adductor Canal Block Performed With Postoperative Thigh Tourniquet Application on Pain After Total Knee Arthroplasty"

Inclusion Criteria Patients aged 40-85 years, with a BMI of 18-35 kg/m², and an ASA physical status of I-III who underwent total knee arthroplasty (TKA) under spinal anesthesia were included. Eligible participants were those who volunteered to participate and provided written informed consent. Exclusion Criteria To ensure methodological standardization, the following cases were excluded: Patients undergoing revision surgery. Those undergoing unicompartmental (unicondylar) knee replacement, as the severity of surgical trauma differs from total replacement. Bilateral cases, to prevent potential bias in assessing postoperative opioid consumption and pain scores. Additionally, patients were excluded if: The surgical duration exceeded 180 minutes. There was a known history of coagulopathy, peripheral neuropathy, or allergy to local anesthetics. The spinal anesthesia was insufficient, requiring a conversion to general anesthesia.
