We present a deep learning-based knee osteoarthritis grading system that automatically provides a binary classification for cartilage degeneration. The system was trained on MRI data sets applying MOAKS grading from the Osteoarthritis Initiative (OAI). The proposed method achieved an accuracy of 0.75 to 0.83, despite being conducted on highly imbalanced data sets. Significant improvement in accuracy is expected with more balanced data sets.
