Wide association study of radiological features that predict future knee OA pain: data from the OAI

In this work a case-control study was done using available data form participates in OAI databases. All case-control subjects present no evidence of pain, no medication for pain, and no symptomatic status, case subjects developed pain in some time point of the study. Radiological information was evaluated with a quantitative and a semi-quantitative score by OAI radiologist groups. The multivariate models obtained in the Bioinformatics study suggest that can exist an association between some of the early joint changes and the presence of future pain.
