Equine Osteoarthritis
is a big pain.

Equine osteoarthritis (OA), also known as degenerative
joint disease (DJD), is a painful condition caused by
progressive “wear and tear” of cartilage and other parts of
the joint.1 OA is one of the most common causes of
lameness in horses.1 It can:

  • Lead to poor performance and a shortened career.1
  • Develop in horses as young as 2 years old.1

What can lead to the onset of equine OA in horses?

  • Trauma to the joint from either an acute incident or
    constant concussive forces.2
  • Conformation, immobilization and improper shoeing.2

What are the signs of equine OA in horses?

  • Limping or lameness.
  • Joint swelling.
  • Decreased turnout activity.
  • Stiffness or decreased movement of joints.
