Ultrasonographic changes of the equine stifle following experimental medial patellar desmotomy.

This research study used ultrasonography to examine the effects of a surgery called medial patellar desmotomy on horses, revealing that it leads to lesions in the knee joint (stifle) and that limiting movement post-surgery does not prevent these lesions.

Objective of the Study

• The aim of this research was to employ ultrasonography, a non-invasive imaging method, to understand the impact of medial patellar desmotomy on the stifle of horses. Medial patellar desmotomy is a surgical procedure that involves cutting the medial patellar ligament, which is a part of the equine stifle.

Findings of the Research

• The study revealed that medial patellar desmotomy causes several changes, including middle patellar desmitis, which is an inflammation of the ligament on the middle part of the patella or kneecap.
• Enthesophytes, which are abnormal bony projections that develop at the attachment of a tendon or ligament, appeared in the patella post-surgery.
• There were also irregularities observed in the cartilage of the femoral trochlear groove, a part of the thigh bone where the patella moves.

Implications of the Findings

• The study concluded that medial patellar desmotomy resulted in lesions in the stifle, an essential joint for horse’s movement. This finding indicates complications associated with this surgical procedure that need to be considered during clinical decision-making.
• The study also found that restricting movement after surgery does not prevent the development of these lesions. This indicates that current post-operative care methods may not be sufficient in preventing post-surgical complications and further research is needed to develop more effective recovery strategies.
