Representative examples and saliency maps of deep learning models using (A) radiographs from the Osteoarthritis initiative (OAI) dataset, (B) radiographs from the Multicenter Osteoarthritis study (MOST) dataset, (C) radiographs from the internal dataset, (D) TSE MRI from the OAI dataset, (E) TSE MRI from the MOST dataset, and (F) DESS MRI from OAI dataset. The subjects from the OAI, MOST, and internal datasets underwent total knee replacement in 3, 6, and 1 year, respectively. DESS = dual-echo in steady state, TSE = turbo spin-echo.
