  1. Hi, I think I might have this. I had a torn Meniscus, and I have arthritis. I had surgery a few months ago but now it feels as though a chunk is floating because it floats from side to side or even under the bottom of my knee. It’s very painful when that happens, I can’t bear weight. I move my knee around some and it will go away. Does this sound correct? Will it go away on its own or should I talk to my surgeon again?
