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.
