Summary
# Editorial Summary: Regenerative Medicine for Equine Musculoskeletal Diseases Musculoskeletal injuries represent a significant clinical challenge in equine practice, as conventional repair mechanisms frequently result in inferior scar tissue rather than functional regeneration, leading to high reinjury rates and chronic degenerative progression. Ribitsch and colleagues conducted a comprehensive review of regenerative medicine approaches—encompassing cell-based therapies, tissue engineering, and cell-free stimulation of endogenous repair mechanisms—evaluating their current application and evidence base in horses with tendon injuries, cartilage damage, and degenerative joint disease. Although several regenerative therapies have shown promise in clinical practice, particularly for tendinopathies and joint disorders, the authors highlight a critical knowledge gap: the precise spatiotemporal requirements for bioactive factors needed to trigger tissue regeneration remain poorly understood, resulting in variable treatment protocols and inconsistent outcomes across practitioners. This variability underscores the necessity for continued mechanistic research to optimise therapeutic approaches and maximise the regenerative potential of these emerging techniques. For equine professionals, the review reinforces that whilst regenerative medicine offers genuine clinical benefits, evidence-based selection and application of these interventions—informed by ongoing research developments—remain essential to achieving superior tissue repair and reducing the career-threatening consequences of musculoskeletal disease.

Practical Takeaways
- •Regenerative medicine options (cell-based and cell-free therapies) are available for equine tendon and joint injuries, but treatment results vary due to lack of standardized protocols
- •Traditional repair mechanisms frequently fail to restore full function; regenerative approaches aim to stimulate endogenous healing but require further research validation
- •Discuss realistic expectations with owners—while promising, regenerative therapies do not yet guarantee complete functional recovery or prevent chronic degenerative progression in all cases
Key Findings
- •Regenerative medicine therapies show promising results in equine clinical practice for treating tendon and joint injuries
- •Current repair processes often result in biomechanically inferior scar tissue with high reinjury rates rather than functional tissue regeneration
- •Qualitative and quantitative spatiotemporal requirements for bioactive factors to trigger tissue regeneration remain unknown, limiting treatment standardization
