Total Knee Replacement Under Spinal Anesthesia, Comparison of Postoperative Recovery Versus General Anesthesia: A Retrospective Single-Center Observational Comparative Superiority Study

Intraoperative anesthetic management for total knee replacement (TKR) can be performed under general or spinal anesthesia. These two techniques have their own characteristics and may impact postoperative recovery differently. However, there are no studies in the literature analyzing postoperative functional recovery after TKR surgery according to the type of anesthesia. The objective of this study is to compare postoperative recovery, assessed by the QoR-15F score, in patients undergoing TKR under spinal anesthesia versus surgery under general anesthesia.
