The welfare considerations surrounding intra-articular joint injections in horses, including appropriate use, competition ethics, and pain management.
Joint injections in horses sit at the intersection of veterinary welfare management and equestrian sport ethics. Used appropriately, they provide meaningful pain relief to horses with genuine joint disease, improving quality of life. Used inappropriately to mask pain and enable horses to compete when they should be rested, they compromise both horse welfare and sporting integrity. The welfare-positive use of joint injections involves accurate diagnosis confirming the injection target is the source of pain, appropriate injection technique, realistic assessment of the horse ability to work after treatment, and honest communication between veterinarians, trainers, and owners about prognosis and appropriate workload. Pressure from owners and trainers to inject and compete horses that should be rested is a real challenge to veterinary professional ethics.
