Morphometric Analysis of Tibial Plateau for Knee Arthroplasty and Prosthesis Design

Morphometric Analysis of Tibial Plateau

Abstract

Background: The knee is the largest joint in the human body and provides weight-bearing of the body besides locomotion. The knee joints can be deformed by fractures, osteoarthritis, or other sorts of traumas. One of the treatments is total or unicompartmental knee replacement. To have an accomplished outcome the prosthesis and the resected bone should match irreproachably. The aim of this study was to demonstrate the tibial plateau anatomy, the differences between medial and lateral condyles particularly, and provide that the Anatolian population has differences as other ethnicities have.

Materials and Methods: The current study was conducted on 159 tibia bones. The bones were stored at Anatomy Department in Bursa Uludag University. The tibial plateau bones were photographed in a standardized contrivance and transferred to a digital platform. 16 different parameters on the tibial plateau were measured. The measurements were obtained using Image J software and for the statistical analyses, SPSS  (ver 20.0) software was performed.

Results: As the result of the statistical analyses between Byzantine and contemporary bones; statistical significance was revealed between the medial and lateral condyle. In a comparison of lateral and medial condyles area, breadth and length were greater in the medial condyle in contemporary; when area, circumference, and length were greater in the medial condyle, breadth was greater in the lateral condyle in Byzantine.

Conclusion: To accomplish designing the optimum knee prosthesis, the prosthesis should be designed by considering the basis of differences between not only medial and lateral condyles but also populations.
