Osteoarthritis causes degradation of the flexible tissue of the joints that and it is more common in people aged 50 years or above. However, it may occur in younger people, too. It is the most prevalent and disabling disease still necessitating research in pathogenic mechanisms, predictors of disease progression and responsive techniques to reveal the slow structural changes within a short period. To achieve these imaging modalities may play an important role. Enormous advances are reported due to the recent advancements in technology and availability of large longitudinal datasets. The discussions and summaries of the original publications in this area have been reviewed by Oo WM et al.

According to recent discoveries, MRI has been the most popular modality used to assess the various roles of structural disorders in incident knee osteoarthritis. This helps compare the predictability of individual features of semiquantitative scores for knee replacement and to formulate different disease progression models. More ultrasound studies have been issued, encompassing the proposed semiquantitative scoring system by the Outcome Measures in Rheumatoid Arthritis Clinical Trial group.

It can be thus summarized that as more advanced emerging technologies are developed in imaging, there are great opportunities to formulate novel incident and prediction osteoarthritis models and to find tissue-targeted disease-modifying drugs.
