REPLACEMENT

Current techniques used for total knee arthroplasty rely on conventional
instrumentation that violates the intramedullary canals. Accuracy of the
instrumentation is questionable, and assembly and disposal of the numerous pieces
is time consuming. Navigation techniques are more accurate, but their broad
application is limited by cost and complexity. An experimental trial of a new concept
of computer-assisted preoperative planning to provide custom made cutting guides
that can replace conventional instruments was previously published by the author.
This paper is reporting the clinical results of this technique Computed tomographybased
planning was used to design two virtual templates. Using rapid prototyping
technology, virtual templates were transferred into physical templates (cutting blocks)
with surfaces that matched the distal femur and proximal tibia. Straightforward and
complex cases of TKR were done using the new technique. The technique was
proved useful for cases with extrarticular deformity. Operations were performed using
patient cutting guides with no conventional instrumentation, intramedullary
perforation, tracking, or registration.
