The early clinical results of geometric total knee arthroplasty were
compared with the position of the prosthetic device by a roentgenographic
score system. It was noted that there is a statistically significant
positive correlation between a good clinical result and a well positioned
prosthesis. In addition, it was appreciated that perfect positioning of the
device was difficult to obtain. We believe that the long-term clinical
results, wear resistance, and resistance to prosthetic failure depend on
correct positioning of the devices.
