Oh, man...I had a minor knee thing recently and it wasn't even from training. Planning on going back to training in a month or so and kind of wondering how it will hold up. What did you tear?
I was rolling with a guy and tore my right meniscus. They removed half of it, so I still have half.
This purple belt I used to roll with had a set of moves. He would use a pass I couldn't keep up with and put me in an MMA side mount for striking (he's a fighter) and then apply a submission. I'd escape mount / side 10 times, gas out, and get subbed.
So I practiced a counter for his shtick and ran into a month later at an open mat. I used the escape from side to half guard, which he passed immediately, but it forced him into scarf hold which was outside of his shtick. He was smaller than me and it wasn't good for him. So I upa and roll him over. During the bridge my knee pops, but I wasn't about to let this guy get away, so I roll him over and get to do the whole top game dance. You could say I peaked for a gym roll, and my knee popped doing a basic upa with nothing weird. That fact is really jarring for me.
I'm able to do most things now and I think I'm still getting better, but I still can't jog outside, can't deadlift, can't squat anything more than my 100lb kettle bell, can barely practice shooting. I really worried about eating hard kicks in it, can't escape bottom by bridging.
I can use the elliptical, can jumping jack, can kettle bell squat, can elbow-knee escape from bottom... so I'm hoping I keep getting better. It's been a like six months. It's not like I was training for competition but the thing that kept me in this was the ability to walk into random gyms and spar / roll strangers (indulging my counter-phobia) because my ability put me on a higher level than the kinds of people that would injure me. Now, I feel so weak it is dangerous for me to take on randoms.
I wish I could find a martial art school with an instructor that had an open mat and would just let me hit the bag and roll with people or put on gloves when I feel like it, but I'm from a small town and it's not the sort of place where that goes on. The closest gym I know with game fighters that run open mat is like an hour away.
I can't handle this group exercise class stuff. I don't want to be that old guy that paces the mat when everyone else is doing a takedown.
