Background ChatGPT has proven its value in medical information acquisition and perioperative education. This study aimed to evaluate correlated factors to explore the value of ChatGPT in patient communication. Methods 220 questions were collected from patients undergoing TKA. The selected questions were answered by ChatGPT-3.5. Questionnaires were created and sent to surgeons and patients. Some features of respondents were collected and investigated for analysis. Readability scores were assessed via the Flesch-Kincaid Grade Level (FKGL). Results The most common question from patients was about operation costs. Satisfaction scores from patients and surgeons were both high. Correlation analysis revealed that surgeon’s score was influenced by hospital level and surgery experience. The readability scores for FKGL were high. Conclusions Collecting questionnaires reveals patients' real clinical needs. The results of the study showed that ChatGPT has potential to be a tool for communicating with patients. ChatGPT responses require a high level of education although this level of education can be reduced.
