These are the craziest trimlines for a BK I have ever seen; those shapes do not make any sense and would never work.” Over the next two years, however, I could not get my mind off of what I had seen, and I wanted to know more.

I enjoy reading a great deal of prosthetic historical literature, and I know that Charles Radcliffe, MS, ME pioneered many of the concepts that are still used today in below-the-knee prosthetics.
