Suprainguinal Fascia Iliaca Block vs. Periarticular Injection for Total Knee Arthroplasty

Total knee replacement (total knee arthroplasty) is performed to resurface a knee damaged by arthritis and relieve pain in patients with severely damaged knee joints.Total knee arthroplasty (TKA) is associated with severe postoperative pain, and the management of postoperative pain continues to evolve with the advancement of surgical techniques and pharmacological treatments.Femoral, lateral femoral cutaneous nerve and obturator nerve block is provided with suprainguinal fascia iliaca plan block, which is used for postoperative analgesia, especially in hip surgeries. In this way, the investigators think it can be used as a part of multimodal analgesia in total knee arthroplasty surgery.
