I would now like to appeal to any JREFers who have knowledge and/or experience with the medical condition and physiology of "thigh hernias". Is this supposed to be a thigh muscle hernia? Is there such a thing in the medical record? If so, what do thigh muscle hernias look like? How might a thigh hernia of this sort affect the locomotion of a bipedal subject (human or hypothetical Bigfoot) that has such an injury?
Well, I'm not a doctor, but I have had medical training in nursing and also have had formal training in human anatomy and physiology. Perhaps my judgment will be of some use?
My understanding of muscles and muscle injuries is limited, but I do know that a basic muscle hernia, where the muscle tissue protrudes through the outlying fascia, causes a good amount of swelling and some pain/discomfort. However, it wouldn't look anywhere nearly as bad as the "hernia" claimed to be on Patty's thigh. What would cause something so disfiguring as that would be (to my limited knowledge) a rupture, where the muscle tissue protrudes much more through the outer fascia. Ruptures, however, cause intense pain, as the tough fascia actually cuts into the muscle tissue as it contracts and relaxes in normal movement. If Patty had a rupture in her quadricep, she would barely be able to crawl, let alone walk.
I can't see how a simple muscle hernia would cause such a nasty looking bulge in the leg like that. Especially not with the well-defined edges of it. Simple muscle hernias cause localized swelling with no defined edge (to my knowledge). If I had to make a call just looking at the leg itself, I'd say it was a serious rupture. And if it was a rupture, that animal should be down on the ground, not walking, not even with a "compliant gait."
I would suggest you ask some of the members here with more extensive training on the subjects of medicine or anatomy though -- I think Dr. Kitten is a practicing physician, and she would likely be able to give a more informed opinion.
My references for the information in this post are all classroom-related. I will cite my anatomy professor W. Sanderson, and one of my nursing assessment instructors, L. Luka.

My
opinion? That's just an ill-fitting costume.
