Osteoarthritis or degenerative joint disease (DJD) is one of the main causes of lameness in horses. Osteoarthritis occurs when the cartilage on the joint surface is damaged or destroyed, which produces pain and inflammation. Joints that are the most affected are the tarsus (hock), fetlock, pastern, carpus (knee), stifle and coffin joint. Usually, therapy involves intra-articular medications such as hyaluronic acid and/or corticosteroids, rest,oral NSAIDS (phenylbutazone or banamine), shockwave therapy, polysulfated glycosaminoglycan (PSGAG) such as Adequan, intravenous hyaluronic acid (Legend) and oral supplements that contain glucosamine and/or chondrotin sulfate.
