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

Evaluation of the Effects of Regional Anesthesia Methods Applied in Total Knee Arthroplasty on Joint Range of Motion in the Postoperative Period and Patient Satisfaction

This is a single-center, prospective, randomized controlled trial aiming to evaluate the effects of different regional anesthesia/analgesia techniques on postoperative knee range of motion (ROM) and patient satisfaction following total knee arthroplasty (TKA). Ninety patients undergoing elective TKA under spinal anesthesia will be randomly assigned to one of three groups: 1) spinal anesthesia with epidural catheter, 2) spinal anesthesia followed by adductor canal catheterization, and 3) spinal anesthesia with multimodal intravenous analgesia. The primary outcome is postoperative knee joint ROM measured on postoperative days 1, 2, and 3. Secondary outcomes include patient satisfaction, Oxford Knee Score, postoperative opioid consumption, and VAS scores. The study is conducted at Konya City Hospital and will be completed over a 6-month period.
