Abstract
Obtaining accurate bone cuts in Total Knee Arthroplasty (TKA) is
clinically important, though it is often regarded as the least precise
step of Computer-Assisted TKA. The Praxiteles universal cutting guide
positioner aims to improve the guide positioning precision for all
five femoral cuts of any TKA implant.
In this paper we report on our most recent features implemented, and
on the positioning and cutting accuracy of the system. The average
absolute positioning accuracy was measured to be 0.3° in both the
coronal/axial and sagittal planes. In the sawing mode, the final
bone-cut accuracy compared to the planned implant position as measured
in our cadaver test was 0.56° and 1.06° in the coronal/axial and
sagittal planes, respectively, with a average distance error of 0.6mm.
These findings suggest that a robotic guidance can bring a clinically
important improvement in cutting precision in TKA.

Abstract
We
have been working to develop a compact, accurate, safe, and
easy-to-use surgical robot for minimally invasive total knee
arthroplasty (TKA). The goal of our bone-mounted robot, named
Praxiteles, is to precisely position a surgical bone-cutting guide
in the appropriate planes surrounding the knee, so that the
surgeon can perform the planar cuts manually using the guide. The
robot architecture is comprised of 2 motorized degrees of freedom
(DoF) whose axes of rotation are arranged in parallel, and are
precisely aligned to the implant cutting planes with a 2 DoF
adjustment mechanism. Two prototypes have been developed and
tested on saw bones and cadavers--an initial one for open TKA
surgery and a new version for MIS TKA, which mounts on the side of
the knee. A novel bone-milling technique is also presented that
uses passive guide and a side milling tool.
