But actually, in the bottom of a deep squat, you're going to lose lateral knee contact, so to speak. I mean, it's not actually touching or anything like that, but it's very passively compressed under that circumstance. There's that turn into external rotation (ER), where they've got pictures of this on MRIs where they do the extreme end range of passive knee bending. You actually see the tibial plateau slide away from the femoral condyle. They will say that it loses contact, but it was never touching in the first place. But you will see it almost disassociate. So if I'm trying to get that, the only way that happens is with an external rotation turn, external rotation turn.
