Most show horses get hock injections in the lower and middle hock joints, which are two very low-motion joint spaces.

There are three FDA-approved joint injections: intra-articular (IA), intravenous (IV) and intramuscular (IM). The type veterinarians will use depend on the horse’s use, soundness problems and what joints are affected.


Intra-articular is a solution that is injected directly into the joint of a horse. It must be administered by a licensed veterinarian under sterile conditions that has experience with the technique. By administrating an intra-articular injection, veterinarians can maximize the effect of the medication as they are able to inject it exactly where it is needed.
