MCL

I tore my MCL, grade 3, early this year, had a quick recovery and skied strong for the rest of the season. I still had some weird sensation that I figured was likely torn meniscus or a foreign body. Had a scan and have the report and it turns out I do have a torn meniscus but the MCL is torn off the femur. I see the MD on Tuesday. Does the MCL have to be reattached to the bone and if yes what is the recovery time? To complicate matters I tore my PCL 15 years ago. PCL's are seldom repaired and I have skied with no problems since then. If they have to reattach the MCL would they suggest fixing the PCL?
