The Cohort Hip & Cohort Knee (CHECK) is a population-based observational multicenter cohort study of 1002 individuals with early symptomatic osteoarthritis (OA) of knee and/or hip in the Netherlands. The participants were followed for 10 years. The study evaluated clinical, radiographic and biochemical variables in order to establish the course, prognosis and underlying mechanisms of early symptomatic osteoarthritis. The Dutch Artritis Foundation initiated and funded this inception cohort.

This dataset covers the data collection from baseline to 5 years follow-up: T0, T1, T2, T3, T4 and T5. All data files include the variable 'Subject identification number’. Included is a Kellgren-Lawrence radiographic classification covering T0,T2,T5, T8 and T10. Also X-rays of hips and knees of baseline, 2 and 5 year follow-up visits are available. The X-ray data are not included in the dataset, they are stored outside of EASY. More information on the variables can be found in the documentation.
