Fig. 4: Subgroup analysis of sports medicine patients comparing AI and doctor groups.

A Patients in the AI group reported significantly higher post-discharge satisfaction, alignment with expectations, and knowledge scores compared to those in the Doctor group, indicating superior patient experience and education. B At 1-month follow-up, the AI group demonstrated significantly lower anxiety, better knee function, and higher physical health scores, suggesting accelerated early recovery. C These functional advantages persisted at 3 months in IKDC and PCS, while anxiety and mental health outcomes were comparable between groups. D By 6 months, differences across all outcome measures diminished, with no significant differences observed.
