Yes, SO when I did some research I guess their are two ways to do TKR , Mechanical and kinematically. I went with the first and the oldest style to do my knee, Which has caused my issues because it sets your knee in a straight line regardless of how your other knee is or how your previous knee was. The same sensors they use in the procedure for the second style which basically alligns your knee the same way of your old knee. Theses same sensors are also used in correction for your knee if you have problems with the soft tissue when you have mechanical procedure and end up with soft tissue issues such as mine. The sensors slide in and send signals to a monitor that the surgeon uses to tell him/her what is the problem. They then use this information to make corrections (revisions) The problem lies with finding a surgeon in my area who uses these sensors and if I can not find one is it possible that if I wait long enough will my leg ever feel like its not sewn on backwards...lol " using sensors to evaluate revision TkA" or William Leone' these are keywords if you are still interested in these sensors.
