Summary
# Editorial Summary: Cross-sectional anatomy and comparative ultrasonography of the equine medial femorotibial joint and its related structures Stifle injuries rank among the most challenging diagnoses in equine hindlimb lameness, yet ultrasonography—a readily accessible tool in most practices—remained underutilised for this region due to lack of anatomical correlation. Hoegaerts and colleagues conducted a detailed comparative study, correlating gross anatomical cross-sections with ultrasound images to create a comprehensive map of all visualisable stifle structures. By systematically identifying which anatomical features appear on ultrasound at various planes and depths, the authors provided the first definitive reference for interpreting medial femorotibial joint anatomy sonographically. This anatomically-grounded approach transforms ultrasound from a descriptive tool into a clinically robust diagnostic method, enabling farriers, physiotherapists and veterinarians to confidently assess soft tissue pathology, differentiate normal variants from lesions, and communicate findings with greater precision across the equine care team. The work substantially expands the diagnostic potential of ultrasound for one of the most common sites of hindlimb dysfunction in working horses.

Practical Takeaways
- •Veterinarians performing stifle ultrasonography now have anatomical reference material to accurately identify normal and abnormal structures, improving diagnostic confidence.
- •Understanding cross-sectional anatomy of the medial femorotibial joint improves the ability to detect soft tissue injuries causing hindlimb lameness.
- •This comparative approach between gross anatomy and ultrasound images serves as a foundation for standardized stifle ultrasound protocols in equine practice.
Key Findings
- •Comparative gross anatomical sections enable identification of all ultrasonographic structures of the equine stifle, addressing a previous gap in descriptive literature.
- •Ultrasonography is a practical diagnostic tool for soft tissue lesions of the equine stifle when anatomical correlation is established.
- •This study provides the first systematic cross-sectional anatomical reference for equine stifle ultrasonographic interpretation.
