ABSTRACT: The problem considered in this review is related to the frequent use of corticosteroids (COs) (i.e. steroids) in the practice of equine medicine and surgery as a therapeutic strategy in the treatment of degenerative joint disease, commonly known as osteoarthritis (OA). This disease is one of the most common among the equine musculoskeletal diseases, and is clinically characterized by pain, lameness, joint effusion at the initial stage, which usually reduces with the progression of the disease, and reduced physical performance. Although steroids are considered excellent drugs in the control of clinical signs resulting from osteoarthritis, they also influence cellular activity through activation of various signaling mechanisms. However, they can cause adverse effects when administered intra-articularly, since they are immunosuppressive drugs of many cell types. They are also incriminated as suppressors of the chondrocyte matrix synthetic activities, which may contribute to 'arthropathy by corticosteroids', which can also be associated with cumulative injury resulting from improper use (dose and frequency of application) of already damaged joints. The objective of this article is to review information about the advantages and disadvantages of intra-articular COs for treatment of the disease in horses. In addition, some important information of other species is also presented.
