This article presents a brief review of the most current therapies that are used for the relief of the symptoms related to osteoarthritis. The agents used either systematically or locally are described, providing the rationale for their usage in the treatment of osteoarthritis. Moreover, new therapies that have reached clinical evaluations and that can possibly reduce or stop the progression of the disease--namely the inhibitors of metalloproteases--are presented. Overall, it is obvious that significant progress has been made toward the development of new therapeutic agents to reduce the symptoms as well as the structural changes of the disease.
