Welcome to the KNee OsteoArthritis Prediction (KNOAP2020) Challenge!


KNOAP2020 is a challenge to identify which knees will develop symptomatic radiographic knee osteoarthritis within 6.5 years follow-up. We will release baseline magnetic resonance imaging (MRI) data, X-ray images, and certain clinical risk factors for this prediction task. We invite all researcher to participate in the KNOAP2020 challenge.

How does it work?

We will provide a test set of knees that do not have symptomatic radiographic osteoarthritis at baseline. Baseline 1.5 Tesla MRI scans, X-ray images, and clinical variables of the knees are available. Your task is to predict which knees will develop incident symptomatic radiographic knee osteoarthritis after 6.5 years follow-up. Algorithms can be trained and tuned on any suitable data (e.g., OAI data). Additionally, we will provide a small set of data with ground truth.

Each submission will be evaluated against the ground truth. Symptomatic radiographic knee osteoarthritis is defined as frequent knee pain and a definite osteophyte in the same knee. The results will be published on this website. We will also write up a scientific paper, co-authored with active participants that provide sufficient information.
