Brief summary

to investigate the effects of ultrasonography-guided 4in1 block application on postoperative analgesia in patients undergoing knee surgery. After knee surgeries performed with spinal anesthesia, 4in1 block will be applied in one group and medical analgesics will be applied in the service in the other group.
