Summary

A single-center retrospective cohort study was conducted in the Department of Orthopedics of Fujian Medical University Affiliated First Hospital. This study reviewed 28 patients who received unicompartmental prosthetic joint infection (uPJI) treatment at this institution from 2017 to 2023. The personal information of the patients, including age, gender, affected side, age-adjusted Charles Syndrome Index (aCCI), inflammation markers, lesion range on magnetic resonance angiography (MARS-MRI), lesion range observed directly during surgery and surgical methods, were recorded in detail. The study evaluated the clinical decision-making of a standardized MARS-MRI-guided treatment protocol for uPJI by reviewing the clinical outcomes of uPJI patients in a single PJI center.
