Brief summary

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

Detailed description

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.

Design outcomes

Primary

Measure	Time frame	Description
Radiology outcome	30/06/2023	Position of implants compare to the plan on CT, measure the discrepancies by degree
Clinical outcome, self-administered questionnaire	30/06/2024	Western Ontario and McMaster Universities Arthritis Index (WOMAC) score, from 0-96, lower is better
Clinical outcome, by surgeon's evaluating	30/06/2024	The 2011 Knee Society Scoring System, from 0 to 100, higher is better

Other

Measure	Time frame	Description
AP-ML dimesion	30/06/2023	Size of knee on stimulated bone resection slice, AP and ML dimension in millimeters
