Hi, I'm trying to make a decision, long distance, re: my son who is a freshman at CU Boulder (we live in Northern CA) - injured his PCL (non sport injury, but plays sports). He saw an OS there and needs to have surgery (donor tissue graft). My question is - can it wait until early May? We can rush to do it out there over his spring break - recouping in a hotel, but if no serious issues would prevent it - I would rather he wait til the semester ends, first of May, and have it done back home. I've not been successfull in finding any answers to this question. Also - the OS he is seeing out there has scheduled surgery for 3/18, but isn't having my son do any pre-op rehab at all. Any idea as to why not? Thanks for any help on this.
