R, I tore my MCL quite nicely & ruptured my PCL all at the same time a few years back.

All i can say is- you can get back into biking once nicely healed. When they mention 6 weeks healing time, they mean it, possibly a wee bit longer depending. Don't fret & keep yourself moving in that time.

Swimming was the only thing that I could do whilst off my bike & all that kept me from going insane.
