Sometimes we don't value how we treat our legs. One of the most important things that you can do is to take care of your knees. I understand that some people exercise and they place a great strain upon their knees when lifting healthy weights. When the time comes and you have to have surgery on your knees please be aware that before you finish the surgery, have a Rollater in place so that you can get around. I know it's going to be hard for some patients to bend their knee but that is the only way you're going to be able to feel some semblance of freedom a couple of weeks after when you have to bend your knee and get around.
