Influence of positioning of prosthesis in total knee replacement.
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.
