Total knee arthroplasty (TKA) is a very common operation that increases in frequency with advancing age. Similar to other surgical procedures, strategies are being developed to minimize morbidity and mortality while allowing for rapid recovery and early hospital discharge. TKA causes moderate to severe postoperative pain for most patients. The goal of pain control after TKA is to provide excellent analgesia, early mobilization and rehabilitation, and to minimize opioid use, including overprescription of opioids after discharge Multimodal, opioid-sparing strategies for postoperative pain control include regional analgesia techniques (e.g., peripheral nerve blocks, LA infiltration, continuous epidural analgesia, neuraxial opioids) in addition to multimodal systemic analgesics. Periarticular injection (PAI), also called local infiltration analgesia, and adductor canal block (ACB), a peripheral nerve block, are increasingly used as a component of multimodal postoperative analgesia and have been shown to reduce pain scores and opioid consumption after TKA. However, the impact of these modalities on the quality of postoperative recovery is unknown. The most widely used method of measuring this is the quality of recovery 40 (QoR 40) questionnaire. This questionnaire places increasing emphasis on measuring overall patient recovery and how quickly a patient can return to daily life after anesthesia and surgery. Numerous studies have used the postoperative QoR-40 to compare different methods of anesthesia, adjuvants, regional analgesic techniques, and other factors on patient recovery and have been validated in Turkish.

This study will be carried out prospectively and randomized on 60 people after obtaining the approval of the ethics committee of Atatürk University Faculty of Medicine Hospital and the written consent of the patients. Patients will be randomized by a statistician using a computerized random numbers table and divided into 2 equal groups as Group PAI+ACB and Group ACB. All patients will undergo spinal anesthesia with 12 mg isobaric bupivacaine + 15 mcg fentanyl. Afterwards, patients in Group PAI+ACU will undergo PAI by the surgeon with a total of 120 ml of local anesthetic-containing fluid before cementing during the operation, and patients in this group will undergo ACU with 15 ml of 0.25% bupivacaine and 1:200000 thousand adrenaline at the end of the operation. Patients in group ACB will have an adductor canal block catheter placed at the end of the operation and 0.1% bupivacaine will be given postoperatively through this catheter as a bolus every three hours. Patients will be given 1000 mg acetaminophen every six hours starting from the preoperative period, 8 mg iv dexamethasone, 4 mg iv ondansetron, 100 mcg/kg/min propofol infusion intraoperatively, 100 mcg iv fentanyl or 10 to 40 iv ketamine for analgesia when necessary, and 400 mg iboprufen every eight hours in addition to acetaminophen, 5 or 10 mg oxycodone for pain, and 25 mcg fentanyl for severe pain (VAS≥7) postoperatively. Patients will also receive 1 gram of tranexamic acid before skin incision and at the end of surgery. QoR40 scores of the patients will be evaluated and recorded on the preoperative day and postoperative days 1 and 2 using the Turkish version of the QoR40 score.
