slippery court

My 13 year old daughter has recently begun practicing with her AAU team and the court they practice on is very, very slippery. I am surprised they even practice there. She just had surgery for a torn meniscus the end of August. She tore it due to a hyperextension injury. I have been a little concerned about her practicing on this gym but now they have planned a scrimmage. Should I be concerned about her reinjuring the knee? Any suggestions?

That's a tough question. I would talk to doctor and/or physical therapist to see if they have any concerns.
