Have i got a rerupture of the ACL and are MRIs safe after ACL surgery?

Hi, i hope you can answer my question. I had an ACL reconstruction a year ago and everything was going great until i had another sport injury. I fell with my leg underneath me, hyperextending the joint and twisting my foot outwards. The motion was very different to the first injury. So far I've had a confirmed MCL partial tear and meniscus tear. Whats bothering me though is there seems to be a little anterior shift on the lachman and drawer tests. It doesn't seem a lot compared to positive videos online but it is more than my uninjured leg. So it seems to be a weird middle ground. There is also what seems to be an end to the tug when i do it myself. My question is, after surgery is it normal for the knee not to be as solid as the good knee od is it likely that it is a rerupture? So far 3 doctors said it feels stable. Also, I'm worried about the safety of an MRI as I'm not sure if any metal was used during the procedure.

Thank you in advance
