Surgical approach for medial meniscectomy in the horse.

The research article describes a surgical method devised for the removal of the medial meniscus in horses. The study shows that the procedure is feasible, but the extent of mobility restriction post-surgery can differ.

Overview of the Research and Methodology

• The research began with preliminary studies on cadavers to develop a surgical approach for removing the medial meniscus, aiming for maximum exposure while minimising damage to the surrounding articular surfaces of the medial tibial plateau and femoral condyle.
• Following the development of the procedure, it was performed on 10 clinically healthy horses under general anesthesia.
• Of the 10 horses, nine were euthanized over a span of one to six months post-surgery, and their joints were examined both on the surface and histologically for closer cellular-level studies.
• The tenth horse was determined to be evaluated a year after the surgery.

Findings

• The researchers diagnosed medial meniscus tears in 5 of the horses.
• In 4 of these cases, medial meniscectomy (removal of the medial meniscus) was performed while one was given rest.
• From these instances, they found that removal of the medial meniscus in horses was achievable through surgical methods developed.
• The subsequent effect on the horse’s locomotion, however, could vary.

Conclusion

• Given the findings, the prognosis for removing the medial meniscus was considered to range from guarded to good.
• The degree of caution in this prognosis derives from the differing levels of locomotor impairment seen after surgery, indicating the procedure’s impact can vary across cases.
