Summary
# Editorial Summary Despite widespread clinical adoption of intra-articular hyaluronate combined with corticosteroids for equine joint disease, robust evidence supporting this practice remained lacking until this Dutch multicentre trial evaluated 80 lame horses receiving either triamcinolone alone or triamcinolone with hyaluronate for treatment of non-infectious synovitis and osteoarthritis. Using a randomised open-label design, researchers tracked lameness resolution, joint effusion, and synovial fluid parameters across both treatment groups over a defined follow-up period. The findings challenge conventional practice: the combination therapy offered no statistically significant clinical advantage over corticosteroid monotherapy, with comparable lameness improvement and joint response between groups. For practitioners, this suggests that the additional cost and complexity of combination injections may not translate to superior outcomes in field conditions, warranting a reconsideration of routine dual-agent protocols and potentially guiding more economical treatment decisions without compromising efficacy in cases of non-infectious joint inflammation and early degenerative changes.

Practical Takeaways
- •This RCT provides evidence-based comparison of two common intra-articular injection protocols for joint disease; results may help practitioners choose the most cost-effective option for lame horses
- •The study addresses a long-standing clinical question about whether adding hyaluronate to triamcinolone injections provides superior outcomes to justify the additional expense
- •Multicentre field trial design means findings are applicable to working equine practice rather than controlled laboratory settings
Key Findings
- •Large-scale randomised controlled trial comparing intra-articular triamcinolone alone versus triamcinolone combined with hyaluronate in 80 lame horses
- •Study designed to evaluate clinical efficacy differences between corticosteroid monotherapy and corticosteroid plus hyaluronate combination for joint disease treatment
- •Multicentre open-label design across multiple equine practice locations
