Brief Summary

Femoral and adductor nerve blocks with ultrasonography(USG) guidance are used effectively and efficiently in post-operative pain management in lower extremity surgical procedures. However, the superiority of these two blocks to each other is still controversial. In this prospective, randomized, double-blind study, patients who underwent elective unilateral knee arthroplasty under spinal anesthesia, will be performed postoperative femoral block or middle adductor canal block with the guidance of USG.Patients who underwent spinal anesthesia and needed sedoanalgesia and who had to switch to general anesthesia will be excluded from the study. The patients will be divided into two groups by simple randomization. Since a total of 52 patients should be included in the study as a result of the power analysis (G-power 3.1); It is planned to take approximately 26 patients for each group.The anesthesiologist, who follows the pain control and mobilization after the block, will not know which study group the patient is in. The blocks will be performed behind the cover while the patient is under spinal anesthesia (Thus, the point of application of the block will not be noticed). In this way, the patient and the anesthesiologist who follows the parameters after the block will be blind to patient's arm. In the first group, 0.25% 20 ml of local anesthetic and middle adductor canal block, in the second group 0.25% 20 ml of local anesthetic and femoral nerve block will be applied We will compare these two blocks in terms of early mobilization, postoperative pain control, motor, and sensory block.
