A cranial intercondylar arthroscopic approach to the caudal medial femorotibial joint of the horse.

The research aimed to develop a new technique, specifically a cranial intercondylar arthroscopic approach, to access the caudal pouch of the medial femorotibial joint in horses for better examination and treatment. The study, carried out with cadavers before proceeding to clinical cases, established the feasibility and advantages of this new technique with minimum complications.

Research Details and Methods

• The paper describes the development and testing of a cranial intercondylar arthroscopic approach to the caudal pouch of the medial femorotibial joint (MFTJ) in horses with the goal of allowing a more complete exploration of the area and easier caudomedial access.
• The researchers first reviewed the regional anatomy and developed this new technique using cadavers. Then, several nonrecovery surgeries were executed to evaluate the effectiveness and safety of the procedure before being used in genuine clinical scenarios.

Results of the Study

• Successful access to the MFTJ’s caudal pouch was achieved in 20 out of 22 cadaver legs, 8 joints in nonrecovery surgery horses, and 6 out of 7 clinical cases operated upon. This demonstrated the high success rate of the developed technique.
• With this technique, the caudal ligament of the medial meniscus and other axial structures in the caudal joint pouch could be visualized more clearly, providing a comprehensive view of the affected area.
• The approach facilitated better triangulation within the joint space and made the caudomedial approach easier, showing the relevance and efficacy of the technique.

Complications and Conclusions

• While the study found that puncture of the caudal joint capsule and scoring of the axial medial femoral condyle were complications, these were minor and didn’t significantly impede the examination or treatment process.
• The study concludes that performing arthroscopic explorations using the cranial intercondylar approach is feasible and offers compelling benefits compared to existing techniques.
• The new approach, according to the study, could augment current techniques and provide useful clinical benefits while being associated with very few significant complications.
