For the past 4 years, Dr. Levengood has been obtaining customized
joints from a Massachusetts-based firm called ConforMIS. He sends a CT
scan of the knee, as well as imaging slices of the hip and ankle in order to
map the center of alignment. Computerized printers that are able to create
solid objects layer by layer use the CT imaging data to form a wax mold of
the knee joint, with which the company casts metal implants precisely the

company sends sterile, single-use, calibrated instrumentation designed
and 3D-printed specifically for use in each case.
