Knee Osteoarthritis Analysis with X-ray Images using CNN

Knee Osteoarthritis Analysis

Pipeline of knee osteoarthritis grading pipeline, which includes knee joints detection and knee OA grading.

DetJoint

• Detecting two knee joints in X-ray images using a customized YOLOv2 model.

ClsKL

• Classifying the KL grade of detected knee joints with a novel ordinal loss.

Data & Models

Knee joint detection (DetJoint) and KL grading (ClsKL) training/testing datasets, as well as best models, can be downloaded from KneeXrayData, around 7G.
