Yes, athletes recover from that just fine at that age.Two ACLs in the same knee before the age of 22 is almost a non-issue to you? K
I'll training a college soccer girl who just came off her 2nd ACL surgery on the same knee and she is a much better athlete at 21 than she was before at 19. Maybe she would be better of without injuries but she also probably would not have trained properly or worked as hard if not.
I'm sure 7+ years down the road it will be a bigger negative effect but not at this stage. Acls are not that big of deal anymore.
