    Machine learning models show high performance in diagnosing prosthetic joint infections (PJI) but lack external validation.

  • 2

    PJI affects up to 1.7% of patients post-arthroplasty, leading to significant morbidity and increased healthcare costs.

    The review included 12 studies, primarily using retrospective data, with sample sizes ranging from 20 to 17,165 surgeries.

  • 4

    Reported AUC values for diagnostic performance ranged from 0.68 to 0.993, indicating varying levels of accuracy.

    The authors call for multicenter studies and standardized data to enhance the robustness and clinical applicability of machine learning models.
