Emerging therapeutic targets for osteoarthritis

In reviewing these targets, it is clear that the field of therapeutic targets for osteoarthritis has grown tremendously. We have gained a better understanding of previously identified targets, identified new targets, and have the opportunity to explore enhanced drug delivery via viral vectors. Regardless, translation to clinical benefits is still lacking in most cases. We propose that this may be due to the heterogeneous nature of the disease, lack of early diagnostic markers, mismatched preclinical animal models and clinical populations, and the complex role of many targets of interest.
