We have some plausible ideas like dynamic valgus, but how does that tear the ACL without any injury to the MCL? How would we answer such a question? Will JW survive the current heatwave in Minnesota?

Preferential loading of the ACL compared with the MCL during landing: a novel in sim approach yields the multiplanar mechanism of dynamic valgus during ACL injuries.
