Yup.
I was a purple belt and was rolling with a regular training partner ( Mike Simpson - who BTW, wrote a terric and funny book partially about his BJJ experiences https://www.amazon.com/Bruises-Divor...ichael+simpson) and tried to pull off a simple scissor sweep. Mike defended by putting a bit of weight on my top knee (not really all that much weight either) and RIPPPPPP, I felt and heard a sound like canvas tearing. Then the pain hit, and my leg was locked in a 3/4 extension position. 80% of the meniscus had torn and parts of it rolled under my kneecap. Surgery and rehab followed.
The knee injury had almost nothing to do with BJJ - it was the previous 28 years of martial arts training (done with a lot of ignorance in how to do it properly and protect my body). We can make a lot of credit card purchases on our body over time, but if we are not careful, eventually we have to pay off the debt.
