Horse Arthritis Management: Evidence-Based Welfare Approaches

Osteoarthritis is the most common cause of chronic pain and reduced performance in horses. Evidence-based management combining veterinary treatment, appropriate exercise, and environmental modification significantly improves equine welfare.

Key Facts

Osteoarthritis affects approximately 60% of horses over the age of 15
The condition causes chronic pain that often goes unrecognized because horses mask pain as a survival mechanism
Joint injection with corticosteroids or hyaluronic acid provides 3-6 months of pain relief in affected joints
Low-impact regular exercise is beneficial for arthritic horses — complete rest worsens joint deterioration
Non-steroidal anti-inflammatory drugs (NSAIDs) like phenylbutazone provide effective pain relief but require monitoring
Therapeutic farriery — specialized shoeing — can significantly reduce pain by improving joint alignment
New treatments including PRP, stem cell therapy, and IRAP are showing promise in clinical trials

Welfare Considerations

Equine arthritis is frequently underdiagnosed and undertreated. Horses evolved to mask signs of pain and weakness — displaying obvious lameness means a wild horse would be targeted by predators. This survival mechanism now works against welfare in domestic settings, as owners may not recognize subtle signs of pain including stiffness after rest, reluctance to flex joints, changes in temperament under saddle, or shifts in posture. Regular lameness evaluations, including flexion tests and force plate analysis, are essential for early detection. The welfare goal is to maintain comfort and quality of life, which for many horses means modification of workload rather than complete retirement — carefully managed, appropriate exercise is both physically and psychologically beneficial.

What You Can Do

Schedule annual lameness evaluations with a veterinarian, especially for horses over 10 years old
Learn to recognize subtle signs of pain: stiffness, shortened stride, reluctance to work, attitude changes
Work with a farrier experienced in therapeutic shoeing for horses with joint problems
Maintain appropriate body condition — excess weight significantly worsens arthritic pain
Provide adequate turnout and social contact, as complete stall rest worsens arthritis
Discuss multimodal pain management with your veterinarian rather than relying solely on NSAIDs
