Brittany Sykes of Syracuse tore her ACL last March. In her third game back, just a couple days ago, she tore the same ACL again.
Obviously, it's different for every person, but it just seems to me erring on the side of caution is the way to go. If you have two ACL operations on the same knee, that's pretty much a guarantee of early arthritis and really, a lifelong issue.
Now if you're coming back for a contract worth several hundred thousand dollars, maybe it makes sense to push it. But Candace Parker rushed back in high school, and her knee still bothers her. She's a great player, but her defense is way below par, and some say it's because her lateral movement isn't there because of her knee issues.
Again, some kids are good to go in five months and never feel a twinge again. You just never know ...
