What a mess, this is a complete 2007 false start:
This is a fissure in my right inner meniscus. I was doing NOTHING and suddenly I felt a sharp pain and I could not walk anymore...
My doctor says, it will take 2 weeks after Arthroskopy

There was(is) a lot of research stating to the effect that meniscus repair is not always required (i.e., it will heal itself). My wife went through a torn meniscus and a terrible arthroscopy and was later told by at least 3 docs that the arthroscopy was unnecessary.

You might want to check this out before going ahead.

Good thing there are 365 days in a year. You've got plenty of time to get started again. Heal quickly!
