I think that PennHip measures the hip laxity and not so much the hip structure as OFA does. Most researchers use OFA as the gold standard for evaluating a hip for dysplasia while they use PennHip for hip laxity. I have an article from the Cornell Canine Genetics course that I took several years ago. The article deals with the mode of inheritance of HD and it seems to be a combination of structure and laxity. One point that they mentioned is that the hip laxity alone does not cause HD while structure alone does. That is why they considered the OFA as the better of the two tests. All the best, Susan Cochran
