I just wanted to share my experience. I tore my meniscus 2 times in the same knee within 3-4 years or so according to MRI. Both were done in martial arts and both doctors, well one more than the other recommended surgery, but I didn't do that. I took extreme measures upon myself to heal. I did a perfect diet, fasting, various injections, lots of exercises and some other stuff and I gave it time, like many months. The 2nd time I was limping around for like 2 months with a sharp stabbing pain before I slowly started getting better. Now a few years later I snowboard, do box jumps, frog jumps and pretty much do everything as usual. It doesn't feel exactly perfect but it doesn't bother me 98% of the time.
