I am planning to do precice femurs 1 side at a time and go back to office all along on crutches. If I lengthen as little as 5cm and explain to people that I had an accident will they be able to notice the difference in length? I can purchase elevator shoes and strip off the lifts and padding for the longer leg. I can wear baggy pants to hide where my knee is. It will be a problem when I sit on a chair and I will have to "tilt" myself and hide the 5cm discrepancy.
