I had a knee replaced yesterday. I know doing exercises at home and all the physical therapy is crucial to getting back to normal. Well I should say hopefully back to a point where walking and steps aren't painful. As I understand it from my limited knowledge they've made great strides in joint replacement. This is basically a cap that fit's over the femur and tibia. It should when I hope after the pain subsides make it much easier to be active. I also feared that if I didn't get it taken care of I would overload the other knee because of using it more. Sometimes going up a ladder and occasionally steps using only the good knee to take the pressure off the bad one. As has been mentioned before getting old isn't fun. I try to tell young and new employees in my job that work smarter not harder. So don't be a "macho man" and lift things to show you can. Our trucks have cranes for a reason. I will do updates for anyone who might be interested. My first therapy session is this afternoon.
