I have some questions about what happens years after ACL surgery.

Do you find that there is movement, or sliding, in your knee? I
sometimes feel like my knee is moving slightly sideways and get a weird
feeling there.

Is a reconstructed ACL likely to be looser than a healthy original one?

My reconstructed ACL is from thigh muscle. Do you think that this
could loosen up with time? It's nothing like when it was completely
torn but I wonder if it is as strong as the original.
