Major props to the OP. He or she shoudl go to medical school. How did they now that she tore it. I'd assume if you jogged another mile it wouldn't be torn.
She has a complete tear of her right ACL.
To give some clarity of the situation from the other postings, you have to look at the whole situation. As another poster said, a partially torn MCL, medial meniscus and ACL is common and known as the unhappy traid. They are most likely to occur together. Based on the video it appears that once the leg got caught there was that anterior and rotation component.
So the ACL is the primary stabilizer and there is an increased risk of tearing it as knee flexion increases. So the MCL, is the medial stabilizer however its distal attachment goes partially into the medial horn of the medial meniscus which leads to the "triad" of the injury
To go onto the next part of Rojo comments regarding pain and to confirm what another poster said. If it's a complete there, individuals are likely to experience no pain at all except for that initial pop due to the severing of the nerve fibers (think 127 hours). Yet if there are still fibers connected and you try to get it to do its normal job, your body will do everything in its power (ie pain signals) to get you to stop it and protect the area.
My theory is that something happened (mild to moderate injury) she was able to get back up with some discomfort, get back over to the NZ athlete but when she tried to run (ie an increase in force) lead to further damage/knee buckling.
Now, she gets back up and jogs the next mile in. A good theory is that she is in pain during this but adrenaline can also mask those feelings until after its over.
Is she still able to run?
Based on the dx, its probably a complete (grade III acl tear, complete tear), with a medial meniscus injury and an grade I or II MCL sprain. The MCL will heal on its own given a decrease in activity (rest). She might have felt something catching or locking in her knee joint as she tried to extend her leg during her stride.
Now onto the ACL, the ACL prevents anterior translation of the tibia and femur. You actually don't need your ACL to run or walk. Some individuals who lead more sedentary lifestyles will forgo surgery. We call these people copers. With keeping your quads and hamstrings strong they can act like a brace in a sense surrounding the knee joint to maintain that stability.
Given the level of competition and fitness for her, it's no doubt she was able to rely on these to finish the race out. Now if she went to rotate, turn, pivot quickly, she would have most likely not been able to do that.
In terms of ACL reconstruction. We have come a long way. Only about 8-24% fail afterward requiring a secondary surgery. Some guidelines, I haven't worked with any doctors who allow running no sooner than four months out. Most people think it's about reinjury the new ACL but the ACL is healthy. Its more about the bone remodeling occurring right then in which it's the weakest about 2-3 months out (ie how they anchor the knee acl into the femur and tibia).
*I could source alot of this information if anyone requests it. Also I'm happy to pop back in and answer any other questions about it.
