This study is a prospective, randomized, double-blind, placebo-controlled clinical trial designed to evaluate the postoperative analgesic effects of intraarticular tramadol and tramadol combined with dexamethasone in patients undergoing knee arthroscopy. Patients scheduled for elective knee arthroscopy under general anesthesia will be randomly assigned into three groups in a 1:1:1 ratio: placebo (saline), tramadol, and tramadol plus dexamethasone. At the end of surgery, after aspiration of the irrigation fluid, the study solution will be administered intraarticularly in a standardized volume. The primary outcome of the study is postoperative pain intensity assessed by the Visual Analog Scale (VAS). Secondary outcomes include time to first analgesic requirement, total analgesic consumption within 24 hours, and the incidence of adverse effects such as nausea, vomiting, itching, and shivering. This study aims to determine whether intraarticular tramadol provides effective postoperative analgesia and whether the addition of dexamethasone enhances this analgesic effect.
