The goal of this clinical trial is to test and learn about Virtual Reality (VR) providing preoperative information to patients undergoing elective TKA surgery in spinal anesthesia. The main question(s) aim(s) to answer if:

Can preoperative information through a VR headset lower the patients preoperative anxiety?
Can VR information make the patients more ready for surgery. Painscore will also be collected.

Participants will be randomized into two groups. One that will have preoperative information through VR versus standard information.

If there is a comparison group: Researchers will compare enrolled TKA patients to see if VR have an impact on anxiety, readiness and pain
