Effect of virtual reality hypnosis on intraoperative sedation needs and functional recovery in knee arthroplasty: a prospective randomized clinical trial.

Background And Objectives: Perioperative psychological stress and pharmacological anxiolysis can negatively affect the quality of recovery after total knee arthroplasty. We aimed to assess whether hypnosis combined with virtual reality could reduce intraoperative pharmacological sedation and improve quality of recovery after total knee arthroplasty surgery.

Methods: In this prospective randomized clinical trial, 60 patients scheduled for total knee arthroplasty with spinal anesthesia were randomly divided into 2 groups of 30 patients each.
