Osteoarthritis and your horse

Osteoarthritis (OA), or degenerative joint disease (DJD), is a painful condition caused by progressive "wear and tear" of cartilage and other parts of the joint. It is one of the most common causes of lameness in horses and can develop in horses young and old. All too often, it leads to poor performance and early retirement.1

Factors that contribute to the onset of OA in horses include:1


When a horse suffers from OA, the cartilage, bone and soft tissues in the joint deteriorate. These changes cause pain, deformity, loss of motion and decreased function. The joints most frequently affected by OA include the carpal, fetlock, pastern and coffin.1

Watch for these signs in your horse:
  • Limping or lameness
  • Decreased activity or exercise (reluctance to stand, walk, trot or canter, or difficulty performing these activities)
  • Stiffness or decreased movement of joints

If you see these signs, talk to your veterinarian about the possibility of osteoarthritis.

As with any prescription medication, prior to use, a veterinarian should perform a physical examination and review the horse's medical history. A veterinarian should advise horse owners to observe for signs of potential drug toxicity. As a class, nonsteriodal anti-inflammatory drugs may be associated with gastrointestinal and renal toxicity. Use with other NSAIDs, corticosteroids or nephrotoxic medication should be avoided.
