are there any pain pre-cursors to an ACL tear?
For those of you who have had an ACL tear and/or have sports medicinal knowledge:
I'm talking about the kind of non-contact tears like in the cases of Rajon Rondo, Derrick Rose, Lou Williams, etc. Where a player plants their foot somewhat normally and the ACL just gives out.
Does it always happen spontaneously or is there ever a sensation in the knee that may warn of an impending tear?
