ACL re-injury

Hello,

I am a qualified physiotherapist and currently i am conducting my dissertation for my master degree in UK. I would really appreciate your help, if any of you have an experience with an athlete regarding a second ACL injury after returning to the sports field. I will collect data via skype, chat or e mails -no more than 15 minutes- and i would really appreciate it if you can help me with that.
Please contact me as soon as possible.

Thank you in advance
