For 30 years, JoCoOA has established itself as one of the premier longitudinal research studies world-wide regarding the epidemiology of osteoarthritis.
The first study, published in ACR Open Rheumatology, describes the prevalence of knee outcomes at four time points from 1999 to 2018 in the JoCoOA.
