AUTOMATED DETECTION AND SEVERITY CLASSIFICATION OF KNEE OSTEOARTHRITIS USING A SCALABLE CONVOLUTIONAL NEURAL NETWORK

Osteoarthritis of the knee is a common degenerative joint condition that lowers quality of life and causes disability, especially in people over 60. It is brought on by the knee joint's degenerating cartilage, which causes bone-on-bone contact, discomfort, stiffness, swelling, and restricted movement. Deep neural networks, specifically “CNNs (Convolutional Neural Networks)”, have shown a lot of promise in medical image processing for the identification and classification of diseases. In order to categorize knee osteoarthritis utilizing X-ray pictures into five groups—Minimum, Healthy, Moderate, Doubtful, and Severe—this research presents SCSNet, a deep learning model. Precision, recall, F1 score, and accuracy had been employed to compare the model's performance to three pre-trained transfer learning models: “VGG-16”, “ResNet-50”, and “Xception”. According to experimental results, SCSNet outperformed the transfer learning models in every metric assessed, achieving higher performance with 98% accuracy.
