Impact of anesthesia type on postoperative pain and outcomes in primary hip and knee arthroplasty: a retrospective register analysis.

Background: This study explores the effects of single-sided spinal versus general anesthesia on patients undergoing hip and knee arthroplasty within a fast-track surgery environment. Although many studies suggest better outcomes with neuraxial anesthesia in lower extremity joint replacement, its benefits in fast-track surgery remain unclear.

Methods: A retrospective analysis was performed on data derived from 283 patients.
