I have torn both knees medial meniscus and had them scoped and repaired in 97/98 and then tore the left knee ACL (post cruciate ligment), word to the wise, 1) spend the money and go to the best sports orthopedic doc you can find (I used the team docs for the the San Diego Chargers, Dr. Paul Murphy) 2) go to rehab often and do not miss an appointment 3) use your own body/knee parts, the knee will actually heal stronger and better than the "original" design physically. I had my knee repaired in 99' and ride about 25 days a season and feel great 4) train/stretch/stay in shape 5) this is very important, ask for a physical therapy pump that circulates cold ice water around the knee, use it often (the company is in Vista, CA, sorry I do have the name, I slept with it and used it 24-7, if I can find out I'll email you back)
