I certainly would have considered this before my knee replacement, but I don't know what it would do for me now. Yes I have pain at times, but nothing too bad until it dislocates. My real issue is that my knee dislocates so very easily and when it does the pain is unreal. My knee has dislocated three times (about once a year since it was replaced) and when it does dislocate it is crazy painful. Unfortunately I can't predict when it will happen. The first time I was playing with trains my grandson. The second time, I was in bed and had dropped something on the floor that rolled under a tad the bed. I got out of bed to retrieve it and as I reached under the bed for it, my knee dislocated. The last time I was gardening. I was kneeling on one knee (my good knee), when I got a random muscle spasm in my other leg that forced me to stand up quickly and rub my leg. Once standing, I realized that my left knee had dislocated as I stood up. So there I was standing on one leg in my garden unable to walk or move. I was laterally stranded standing there on one leg for over an hour and half before my wife noticed that I hadn't moved. I feel like a ticking time bomb. We don't got any where without bringing a set of crutches with us.
