Regional Anesthesia in TKA: Impact on Postoperative Joint Motion and Patient Satisfaction

This single-center, prospective, randomized controlled trial aims to compare the effects of three different postoperative analgesia techniques following spinal anesthesia in patients undergoing total knee arthroplasty (TKA). The study will assess the impact of combined spinal-epidural anesthesia, adductor canal block, and multimodal intravenous analgesia on postoperative knee range of motion (ROM). Secondary outcomes include patient satisfaction, opioid consumption, Oxford Knee Score (OKS), activity levels, and visual analog scale (VAS) pain scores.
