Osteoarthritis Management in Horses: Multimodal Approaches for Comfort

Equine osteoarthritis is a leading cause of chronic pain and reduced performance, with multimodal management providing substantially better welfare outcomes than single-modality approaches.

Key Facts

OA affects approximately 60% of all lameness in horses and is a leading cause of retirement
Common sites include the distal interphalangeal joint (coffin), fetlock, hock, and stifle
Intra-articular corticosteroids provide 3-6 months of anti-inflammatory relief for most joints
IRAP (interleukin-1 receptor antagonist protein) and PRP provide joint-protective effects
Systematic use of NSAIDs (meloxicam, phenylbutazone) manages pain between joint treatment cycles
Therapeutic shoeing reduces mechanical loading on affected joints
Complementary approaches including physiotherapy and controlled exercise maintain joint health

Welfare Considerations

Equine OA causes chronic pain that progressively impairs movement, normal behavior, and quality of life. Many horses suffer unrecognized chronic joint pain because subtle behavioral and gait changes are attributed to training issues rather than pain. Multimodal management combining joint treatment, systemic analgesia, therapeutic shoeing, physiotherapy, and appropriate exercise modification provides substantially better welfare outcomes than any single approach. Regular joint reassessment ensures treatment plans are adapted as disease progresses.

What You Can Do

Establish a baseline joint assessment with your vet and develop a proactive OA management plan
Schedule intra-articular treatment at appropriate intervals before flare-ups occur
Use NSAIDs during higher-intensity work periods to reduce post-exercise joint inflammation
Work with a specialist farrier on therapeutic shoeing appropriate for the affected joint
Integrate physiotherapy to maintain muscle support around affected joints
Monitor behavioral signs of OA: reluctance to work, stiffness after rest, altered performance
Modify exercise type and intensity to manage joint loading while maintaining fitness
