Abstract :Objective: Total knee arthroplasty is an effective treatment for end-stage knee osteoarthritis. Inadequate or inappropriate postoperative pain management after this surgery can prolong hospitalization and increase the need for intensive care. This study investigates the effects of femoral, sciatic, and obturator nerve blocks on postoperative pain, additional analgesic consumption, postoperative nausea-vomiting, patient satisfaction, and length of hospital stay. Material and Methods: The study involved 50 patients who underwent unilateral knee arthroplasty and peripheral nerve block for postoperative analgesia between October 21, 2020, and February 21, 2021. The patients were randomly divided into two groups: group I received femoral and sciatic nerve block, while group II received femoral, sciatic, and obturator nerve block. Resting Visual Analog Scale scores, as well as nausea and vomiting symptoms, were recorded at 0, 2, 4, 8, 12, and 24 hours postoperatively. Additionally, we evaluated dynamic Visual Analog Scale scores at 8, 12, and 24 hours, initiation times for additional analgesia, total analgesic use within 24 hours, discharge times, and patient satisfaction levels. Results: The resting Visual Analog Scale scores at the 4th and 8th hour were significantly higher in patients with femoral and sciatic nerve block compared to those with femoral, sciatic, and obturator nerve block. Additionally, patients with femoral and sciatic nerve block required additional analgesics significantly earlier than those with femoral, sciatic, and obturator nerve block. Conclusion: The use of femoral, sciatic, and obturator nerve block for postoperative pain in total knee arthroplasty operations was found to have a positive impact on postoperative Visual Analog Scale score and the time to initiate additional analgesics.
