What the trial is, and whether it could suit you

Virtual reality (VR) uses computer technology to create a three-dimensional environment which the user can explore and interact with. VR can be used to distract the patient during an operation and has been used to avoid sedative premedication, increase patient satisfaction and decrease pain during nerve blocks. VR used alongside spinal anaesthetic for hip, knee and ankle operations has shown a trend of less sedation being required with no decrease in patient satisfaction. The most common type of anaesthesia given during total knee arthroplasty (TKA) is spinal. Spinal anaesthesia is given unless there are complications or other conditions present, and general anaesthesia is given instead. General anaesthesia puts the patient to sleep during the operation, whereas spinal anaesthesia allows the patient to stay awake, but numbs the lower half of the body so no pain is felt. Sedation is usua
