Three years ago I had my medial meniscus operated on. My knee was great...until this year. I twisted my knee in the snow hunting and could hardly walk. My Doc says that most meniscus repairs will become re-injured in the future unless you are really careful. This time I have just taped it up and it is slowly healing. There are several places on you-tube that show you exercises to do to help with healing. However, the first thing to do is go to your doctor to see exactly what is going on. BTW...I had no swelling last time or this time. Good luck.
