Agreement Between Patient-Reported Pain, Observer-Rated Pain Behavior, and Analgesic Request After Total Knee Arthroplasty

Sponsor: Gamze Kübra Zelyurt

Summary

The goal of this observational study is to learn how well patients' own pain ratings match what an observer sees and whether the patient asks for extra pain medicine after total knee replacement surgery. The study will include adults aged 18 years or older having planned (elective) total knee replacement under spinal anesthesia. The main questions it aims to answer are: * Does the pain score reported by the patient (Numeric Rating Scale, 0-10) agree with the patient's request for additional pain medicine? * Does the pain score reported by the patient agree with pain behavior rated by an observer (facial expression, body movements, and vocal expressions)? No treatment will be changed for this study. All patients will receive the hospital's standard anesthesia and pain management. Participants will: * Rate their pain from 0 (no pain) to 10 (worst pain imaginable) at 2, 6, and 24 hours after surgery * Be observed by a researcher who scores their pain behavior at the same time points * Be asked whether they would like additional pain medicine at each time point
