Evaluation of the Effectiveness of Virtual Reality as an Adjunct to Standard Care in Managing Perioperative Anxiety and Pain in Patients Undergoing Lower Limb Orthopedic Surgery Under Spinal Anesthesia

The goal of this clinical trial is to evaluate whether virtual reality (VR) can effectively reduce perioperative anxiety and pain in patients undergoing lower limb orthopedic surgery under spinal anesthesia. The study focuses on adult patients in a surgical setting, with an emphasis on improving intraoperative experience and postoperative outcomes without relying solely on pharmacological interventions. The main questions it aims to answer are: * Can VR reduce perioperative anxiety and perceived pain levels? * Does the use of VR lower the need for sedative and analgesic medications and improve hemodynamic stability and satisfaction? Researchers will compare a VR intervention group to a standard care group to see if VR leads to reduced anxiety and pain, less medication use, better physiological stability, and improved satisfaction. Participants will: * Undergo orthopedic surgery under spinal anesthesia. * Be randomly assigned to either receive standard perioperative care or standard care plus VR immersion. * In the VR group, engage in calming, immersive virtual environments during the perioperative period.
