Outline of Final Research Achievements |
Three-dimensional coordinate system in femur and tibia is usually constructed through manual operation, and therefore artificial errors, namely inter- and intra-observer errors could be expected. The method of fully automatic construction of the three-dimensional coordinate system was established in the previous study using the principal component analysis. The method demonstrated highly reliable and reproductive results when applied to healthy subjects. The objective of this study was to apply such method to the subjects suffered from knee osteoarthritis (OA) so as to clarify its feasibility and reliability. The results were summarized as significantly large differences between the automatic construction and the other methods in varus-valgus and internal-external rotation direction for femur and in internal-external rotation direction for tibia. The causes of such discrepancies were probably due to the presences of the osteophytes and the large joint surface deformation in knee OA.
