Brief summary: The goal of this observational study is to determine the effect of adding adductor canal block to popliteal sciatic nerve block on patient-surgeon satisfaction, intraoperative sedation need, tourniquet pain, return time of motor block, and postoperative pain in patients undergoing hallux valgus correction surgery. The main question it aims to answer are:

* Does peroperative pain decrease?
* Do patient-surgeon satisfaction increase? The patients were divided into two groups, the Popliteal Sciatic Block (PSB) group, and the Popliteal Sciatic Block + Adductor Canal Block (PSB + ACB) group.

Detailed description: Patients were randomly assigned into 2 groups as popliteal sciatic nerve block (Group PSB), popliteal sciatic nerve + adductor canal block (Group PSB + ACB). In this study, 52 patients scheduled for hallux valgus correction operations, in the American Society of Anesthesiologists I-III groups, between the ages of 18-80, were enrolled. Study was planned as a prospective, randomized and controlled trial. All patients were perfomed PSB with 10 ml 0.5% bupivacaine and 10 ml 2% prilocaine in the prone position, using ultrasonography and nerve stimulator. 10 ml of 0.5% bupivacaine and 10 ml of 2% prilocaine were administered to the patients in the ACB + PSB group in the supine position, in addition to PSB. Patients with coagulopathy, infection at the region site of regional blockade, allergy of local anesthetic drugs, peripheral neuropathy and neurogenic disorders affecting the lower extremities, peripheral artery disease, mental retardation and those who did not give consent to study were excluded. All patients were sedated with 1-2 mg midazolam and 50 µg fentanyl. After the blocks were performed , sensory -motor block onset time, surgery-tourniquet time, tourniquet pain, motor block time, pain onset time, first analgesic administration time (NPRS≥4) and analgesic administered were recorded. Anesthesiologists evaluating these data were blinded to group distribution .
