Overview

This study aims to evaluate the effectiveness of virtual reality (VR) in managing preoperative anxiety and postoperative pain in patients undergoing total knee replacement. Investigators will assess the impact of preoperative VR training on anxiety levels, explore the effectiveness of relaxing and distracting VR videos for pain management after surgery, and determine the optimal timing for VR application by comparing different VR intervention times. Our goal is to identify how VR can improve both the emotional and physical recovery process for patients undergoing knee replacement surgery.

Interventions

Virtual Reality Intervention for Preoperative Anxiety and Postoperative Pain Management (2 hours)DEVICE

The Virtual Reality intervention involves participants wearing a VR headset at least one hour prior to their surgery to watch immersive, pre-recorded educational videos showing the operating room with a nurse explaining the process aimed at reducing pre-operative anxiety and nature videos with distraction effect after surgery for pain management. The intervention for pain management will be delivered 2 hours after surgery. The videos to be shown to patients will be limited to a maximum of 30 minutes. In addition, all participants will be reminded that they can remove the glasses or leave the study at any time.

Device: Virtual Reality Intervention for Preoperative Anxiety and Postoperative Pain Management (4 hours)DEVICE

In addition, all participants will be reminded that they can remove the glasses or leave the study at any time.

Virtual Reality Intervention for Preoperative Anxiety and Postoperative Pain Management (6 hours)DEVICE

The Virtual Reality intervention involves participants wearing a VR headset at least one hour prior to their surgery to watch immersive, pre-recorded educational videos showing the operating room with a nurse explaining the process aimed at reducing pre-operative anxiety and nature videos with distraction effect after surgery for pain management. The intervention for pain management will be delivered 6 hours after surgery. The videos to be shown to patients will be limited to a maximum of 30 minutes. In addition, all participants will be reminded that they can remove the glasses or leave the study at any time.

Outcomes

Primary Outcomes

Change from Baseline in Postoperative Pain Intensity as Measured by Visual Analogue Scale (VAS) at 2, 4, and 6 Hours After Surgery in Patients Receiving Virtual Reality Interventions.

0 = No pain 10 = Worst pain possible

Time frame: Baseline (before VR intervention) and assessments at 2, 4, and 6 hours after surgery, with a 15-Minute wait after VR video completion before each pain assessment

Secondary Outcomes

Preoperative Anxiety Measured Using the State-Trait Anxiety Inventory-State (STAI-S) Scale

Preoperative anxiety will be measured using the State-Trait Anxiety Inventory-State (STAI-S) scale, which is a validated tool for assessing temporary feelings of anxiety. Patients will complete the scale before undergoing any intervention or VR exposure. This measurement will provide an understanding of the patient's baseline anxiety level before the application of VR. This measurement will be taken twice: once before the patients view the educational videos and once after viewing them. Total scores range from 20 to 80. Higher scores = Higher levels of anxiety.

Time frame: Baseline (just before the educational video) and post-video (immediately after the educational video, Day 1)

Change from Baseline in Virtual Reality Sickness as Measured by the Virtual Reality Sickness Questionnaire (VRSQ)

The Virtual Reality Sickness Questionnaire (VRSQ) assesses the level of discomfort or sickness experienced by participants during or immediately after wearing the Virtual Reality headset. Total scores range from 0 to 15, with higher scores indicating higher levels of discomfort or sickness.

Time frame: Baseline (just before the educational video) and post-video (immediately after the educational video, Day 1)

Patient Satisfaction as Measured by a 0-10 Numeric Rating Scale Post-Intervention

Patient satisfaction will be measured using a 0-10 Numeric Rating Scale (NRS), where 0 represents no satisfaction and 10 represents the highest level of satisfaction.

Time frame: Postoperative, Day 1

Change in Body Temperature (Celsius) from Baseline
