The association between spaying and MPL/CCL problems was small, but statistically significant. Cause and effect was not implied at all, and one of the possible reasons given for the association is that spayed dogs might (in general) receive better veterinary care, resulting in the the diagnosis of MPL/CCL issues that would otherwise go undiagnosed in unspayed animals receiving less frequent veterinary care. Direct cause and effect have not been proven, and that is why no specialist would mention it at all, unless they were actively involved in this type of research and collecting data for their studies.

If there was significant evidence then vets and actual orthopedic specialist would be using the information. There were issues with the study big issues in my opinion.
