- Abstract summary: We propose a fully automated novel method, based on combination of joint shape and convolutional neural network (CNN) based bone texture features.
Our results demonstrate that fusing the proposed shape and texture parameters achieves the state-of-the art performance in radiographic osteoarthritis detection yielding area under the ROC curve (AUC) of 95.21%.

- Abstract: Knee osteoarthritis (OA) is very common progressive and degenerative
musculoskeletal disease worldwide creates a heavy burden on patients with
reduced quality of life and also on society due to financial impact. Therefore,
any attempt to reduce the burden of the disease could help both patients and
society. In this study, we propose a fully automated novel method, based on
combination of joint shape and convolutional neural network (CNN) based bone
texture features, to distinguish between the knee radiographs with and without
radiographic osteoarthritis. Moreover, we report the first attempt at
describing the bone texture using CNN. Knee radiographs from Osteoarthritis
Initiative (OAI) and Multicenter Osteoarthritis (MOST) studies were used in the
experiments. Our models were trained on 8953 knee radiographs from OAI and
evaluated on 3445 knee radiographs from MOST. Our results demonstrate that
fusing the proposed shape and texture parameters achieves the state-of-the art
performance in radiographic OA detection yielding area under the ROC curve
(AUC) of 95.21%

Cartilage defects are regarded as major manifestations of knee osteoarthritis (OA)
Many attempts have been made on knee cartilage defect assessment by applying convolutional neural networks (CNNs) to knee MRI.
We model the cartilages structure and appearance from knee MRI into a graph representation, which is capable of handling highly diverse clinical data.
Then, guided by the cartilage graph representation, we design a non-Euclidean deep learning network with the self-attention mechanism, to extract cartilage features in the local and global.
