My problems were that my knees were "locking" in the bent position. What is called a bucket handle tear due to it's shape (horseshoe) was flapping around and getting lodged in the knee joint, causing my knee to lock. I literally had to have someone pull my leg straight to "pop" it back into place. You could pyhsically hear the pop and the closer to straight I got it, the more pain until it would release. It BLEW. I had no choice because it started happening more frequently..all of a sudden you turn your knee and BAM your on your ass. My friends knew how to deal with it, but on a wrestling mat or rugby pitch? I was a mess. Sounds like you are not that far along with the tear. Certainly, pounding like running and especially and lateral cutting motion or strain on the knee (push/pulling) with further increase that tear. Just go easy on it. Nothing helped me...braces, knee wraps...nothing could contain that locking. HONESTLY, I wouldn't run anymore. Walk or at a minimum, use the eliptical. Did they "scope" your knee (go inside with a camera and poke around without trimming or fixing)? Usually the tears dont show so well with MRIs. They go inside and discover more than they thought they had on their hands.
