With good rehab some MCL injury patients can return to doing most things within 6 or so weeks - at least that is what I understood? Maybe not all tears - but certainly when my original diagnosis was suspected MCL tear only I was told a return to sport within 6 or so weeks was possible.
OF course I never got to test that theory because in my case it was ACL, MCL, LCL and medial meniscus

A quite common injury is what is known as the 'unhappy triad' - where the ACL, MCL and medial meniscus all get injured in the same mechanism. I guess what happens is as the ACL fails and the knee pops out to one side or another , in the process of doing that it also grinds its way through a meniscus...

I had the unhappy triad - Im back to doing all the things I love - so you will get back to doing what you want to do!
My advice - get the leg working again, get rid of the swelling, nice extension and flexion, and start building up the strength and muscle control in it - you will need it no mater what comes next!
