Effectiveness, Satisfaction, and Usability of Virtual Reality in the Management of Postoperative Pain in Patients Undergoing Knee Arthroplasty

The goal of this clinical trial is to evaluate the effectiveness of using virtual reality glasses to reduce the need for rescue analgesia in patients with acute postoperative pain after knee arthroplasty. The main questions it aims to answer are: * What is the impact of virtual reality use on postoperative pain perception as measured by the Visual Analogue Scale (VAS)? * What potential adverse effects are associated with the use of virtual reality in the postoperative context? * What is the level of satisfaction and acceptance of virtual reality as a complementary strategy for pain management? * How does virtual reality influence quality of life and psychosocial variables in patients with acute postoperative pain after knee arthroplasty?
