To address these challenges and the lack of interpretability found in certain existing automated methods, we have created fully automated software that not only precisely measures the Cobb angle but also provides clear visualizations of these measurements.

The final image classification model, trained using both manually labeled and pseudo-labeled data, had the higher weighted average AUC (WAUC: 0. 903) value and higher AUC-ROC values among all classes (normal AUC-ROC: 0. 894; abnormal AUC-ROC: 0. 896, arthroplasty AUC-ROC: 0. 990) compared to the baseline model (WAUC=0. 857; normal AUC-ROC: 0. 842; abnormal AUC-ROC: 0. 848, arthroplasty AUC-ROC: 0. 987), trained using only manually labeled data.

We propose a novel deep learning-based five-step algorithm to automatically grade KOA from posterior-anterior (PA) views of radiographs: (1) image preprocessing (2) localization of knees joints in the image using the YOLO v3-Tiny model, (3) initial assessment of the severity of osteoarthritis using a convolutional neural network-based classifier, (4) segmentation of the joints and calculation of the joint space narrowing (JSN), and (5), a combination of the JSN and the initial assessment to determine a final Kellgren-Lawrence (KL) score.
