The arthroscopic and ultrasonographic boundaries of the equine femorotibial joints.

This research article explores the combined use of arthroscopy and ultrasonography to gain a detailed understanding of the equine femorotibial joints. The study demonstrates the benefits and limitations of each modality, suggesting that the combined approach can provide a comprehensive view of these joints.

Methodology

In this research study, the authors conducted simultaneous arthroscopy and ultrasonography on 10 equine cadaver stifles. In addition, a nonrecovery surgical procedure was performed on bilateral stifles of a horse. The methodology included:

• The arthroscopic probe was visualised using ultrasonography.
• Concurrent video and still images of the joint structures were captured.

Findings

The results highlighted the individual strengths of each imaging modality. Here is what each of them revealed:

• Arthroscopy: Offered good visualisation of the cranial meniscal ligaments, the distal portion of the cranial cruciate ligament, proximal portion of the medial collateral ligament within the fibrous tissue of the joint capsule, and a limited view of the abaxial border of the meniscus.
• Ultrasonography: Provided almost complete visualisation of the menisci, collateral ligaments, and cranial meniscal ligaments, as well as a segment of the cranial cruciate ligament.

Conclusions

The study concluded that by comparing the ultrasonographically and arthroscopically visible structures, it is possible to gain a more comprehensive understanding of the equine femorotibial joints. Notably, the research suggested that the ability of ultrasonography to detect minor pathological changes should be investigated further. Used together, these imaging modalities could provide a more global image of the femorotibial joints.
