Abstract

Osteoarthritis is the most prevalent form of arthritis and frequently affects the knee joint. While deep learning methods have been widely applied to medical image analysis, three-dimensional models remain underexplored for knee osteoarthritis assessment. In this study, we employ a 3D convolutional neural network (CNN) to analyze knee magnetic resonance imaging sequences and classify disease severity according to the Kellgren–Lawrence grading system (grades 0–4). By capturing spatial correlations across image slices, the proposed approach demonstrates improved classification effectiveness compared with the 2D CNN. These findings highlight the potential of combining volumetric magnetic resonance imaging with 3D CNN to support more accurate knee osteoarthritis evaluation in clinical practice.
