Guys with meniscus tears: have you bounced back?

So a blue belt jumped guard straight into my planted knee. Doc things I tore my meniscus (waiting for MRI results). Ligaments are intact.

I'm slowly freaking out about never being able to train again or developing arthrosis in the knee over the years (those on my elbows are enough if you ask me).

​

Has any of you guys had any experience with this kind of injure? Curious to know how it developed over the time.
