Overview

A 3D Computed Tomographic Study of Vietnamese Knee Morphology for Total knee Replacement

There were controversies and inconsistent results regarding the effectiveness of PSI. However, most authors used PSI from commercial manufacturers. From our view, the surgeon's involvement in PSI planning and design can affect the PSI's accuracy. Some other benefits of in-hospital PSI included the use of any type of implant without depending on the manufacturer's software system, faster and cheaper. Therefore, we conducted this study to evaluate the effect of in-hospital PSI in which the surgeons take part in the manufacturing job.
