| Outline of Final Research Achievements |
Our developed total knee prosthesis, ACTIYAS, showed appropriate posterior translation of medial and lateral femoral condyles. It also exhibited comparable flexion angle to a conventional high-flexion posterior-stabilized design, showing good function. We are submitting a manuscript based on this research.
CT assessment demonstrated negative correlation between ellipticity, and femoral and tibial transverse diameter, showing decreasing ellipticity with increasing transverse diameter, with greater tendency in femur. Size variation of ACTIYAS can be fit to Japanese bone morphology. We are writing a manuscript based on this research.
