And if we're not taught again how to land, how to run, how to jump with the new angles, it predisposes people to severe ACL injury.

It is a higher rate, but the thing about the research is that there hasn't been a direct comparison because we hear incidentally that women tear their ACL. And so we see a lot of observational studies that women have torn their ACL. And we have lots of retrospective studies that are going back to, oh, where are we in our menstrual cycle when we chore ACL?

But there hasn't been a definitive comparison between men and women. If we were to look at the current research, we see a three to four to one ratio of ACL tears of women versus men.

So either three to one or four to one, depending on the research that you look. So three women for every one man or four women for every one man.

In professional sport, it's not as much as when we're looking at recreational sport. Because when we're getting into professional sport, we have specific warm-ups, especially for football, put out by FIFA to prevent ACL tear, to make sure that you are actually properly warmed up

and engaging the right muscles and learning how to stop pivot because it's a mechanism in action usually is a twisting angle. But if we're looking at more age group or grassroots sports, because people aren't aware of this Q angle, they aren't aware of the quad dominance, women haven't been taught again how to work with these new mechanics. Then we're seeing a greater incidence of ACL tear.

Yeah, it's very high incidence. Yeah.

Yeah, it's very high incidence. Yeah.

It's all about being strong. So if we're looking at what is the biggest thing for ACL prevention, and I'll bring in one of my PhD students who's graduated, looked at... ACL rehab after surgery. And it comes down to the definitive difference between quad and hamstring strength.

So if we're looking at improving the strength capacity of the hamstrings, then it offsets some of the default strength that the quads are taking. So if we're able to balance it from being front-loaded to being more even-loaded, it comes down to how we were talking about distribution of forces through the knee with men being more linear and women having an angle.

Well, if we're able to take that angle and we can evenly distribute the load between the muscles of the hamstring and the quads of the front and the back, then it pulls the forces more centrally, which reduces the stress more. of one point of contact.
