I am an orthopedic sports medicine specialist. When I look at that video, it appears that he lands with the right knee flexed and the left knee a little flexed. Does not look typical for a hyperextended knee. Most likely is a knee contusion but an ACL partial or complete tear is not out of the question. FYI, a 'hyperextended" knee is a catch-all term for when they are not really sure about diagnosis. I have looked at thousands of knee MRIs and have never diagnosed a "hyperextended knee" from the MRI.
