About

In total knee arthroplasty, surgical and anesthetic procedures can lead to a significant increase in systemic inflammation. This procedure is frequently performed under either general or spinal anesthesia. However, studies investigating the effect of anesthesia type on systemic inflammation have shown conflicting results. The Systemic Inflammatory Response Index (SIRI) and the Systemic Immune-Inflammation Index (SII) provide important information about the extent of systemic inflammation. This study aimed to investigate the effects of general and spinal anesthesia on perioperative changes in SII and SIRI during total knee arthroplasty. Between January 2020 and April 2025, data from 849 patients who underwent total knee arthroplasty were retrospectively reviewed. Patients received either spinal anesthesia (Group S) or general anesthesia (Group G). The groups were compared in terms of changes in perioperative SII and SIRI (ΔSII and ΔSIRI), total opioid consumption, postoperative complications, and length of hospital stay.
