Introduction
The lateral trochlear ridge (LTR) of the femur is the most common predilection site for osteochondrosis dissecans (OCD) in the equine stifle. The objective of this study was to investigate the relationship between lesion size, racing performance and sale result of Thoroughbreds with OCD of the LTR following arthroscopic removal.
Materials and Methods
In this retrospective study, medical records of 145 Thoroughbreds from one equine hospital that underwent surgery for OCD of the LTR were reviewed, and length and depth of the lesions were measured on pre-operative radiographs. Horses allocated to group S were presented to a public yearling sale post-surgery, and horses in Group NS were not. Each horse from Group S was matched with two control horses from the same sale (Group C). Influence of lesion size on racing performance and sale result was analyzed. Racing performance (Group S vs. Group NS and Group S vs. Group C) and sale result (Group S vs. Group C) were compared.
Results
Lesion size did not affect racing performance, and did not differ between Group S and Group NS. However, group S performed significantly better than Group NS. Comparing group S and C, there were no significant differences in racing performance and sale result.
Discussion/Conclusions
Thoroughbreds that had arthroscopic surgery for OCD of the LTR of the femur as a yearling and were presented on a public yearling sale, performed comparable to Thoroughbreds that showed similar potential as a yearling. Sale result is not significantly affected in our study.
