Patients undergoing elective total knee arthroplasty are randomized to either intrathecal
anesthesia, wound infiltration with local anesthetics and standardized postoperative care (NA
= neuraxial anesthesia) or general anesthesia, intraoperative glucocorticoids with
accelerated postoperative care principles (GA). The study hypothesis is that GA would reduce
length-of-hospital stay. Outcome variables are postoperative nausea and vomiting,
mobilization rate, pain, requirement of analgesics, and length-of-hospital stay.
