PT Inquest Episode 59: Hip Internal Rotation and ACL Fatigue Failure

There is some evidence that repeated loads can fatigue an ACL in a cadaveric model. There is some other evidence that lack of hip internal rotation is a risk factor for ACL injury. This episode explores these ideas and asks how these factors might play a role in this common yet serious injury. How does one tear an ACL? Assuming they matter, is there anything we can really do proactively about these concerns? Can JW afford a new bike? Does Erik have a thing for foot piercings?
