Clinical Trial Summary

Central neuraxial and regional anesthesia and analgesia techniques significantly reduce perioperative morbidity and mortality in the knee and below-knee surgeries.Nerve blocks appear to have better analgesic efficacy compared to placebo or patient-controlled analgesia (PCA). In addition, opioid-related side effects such as postoperative nausea, vomiting, pruritus, sedation, and respiratory depression are less. Therefore, interest in regional blocks such as femoral, sciatic, adductor, combined femoral, and sciatic is increasing. The knee joint is innervated by various nerves (genicular nerves) from the femoral, obturator, and sciatic nerves, and a comprehensive but simple technique is needed for postoperative analgesia. Complete and comprehensive postoperative analgesia was possible with this block, a simple single injection technique. The aim of our study is to evaluate the intraoperative analgesia efficacy of femoral, adductor canal block, and 4in1 block in patients who will undergo knee surgery.
