The magnetic resonance imaging evaluation of morphometry of the distal femur and proximal tibia on adult anatolian population

Abstract

Introduction: It is widely known that the production of knee prostheses is based on the morphometric parameters of the distal femur and proximal tibia. Although there have been studies on this subject in different populations in the literature, such a study has not been found in the Turkish population. It is aimed to establish an index and also compare it with previous results of different populations, in this study. Material and Methods: This study was conducted on 200 patients (78 females, 122 males) aged between 18 and 65 years who had magnetic resonance imaging retrospectively. People with previous fractures, dislocations or ruptures, tears, or tensions in the anterior cruciate ligament, history of knee surgery, and trauma were excluded from the study. Various measurements were conducted on images of the distal femur and proximal tibia morphometry. Results: Mean values of the measurements made on the distal femur and proximal tibia were calculated, it was determined that all parameters were higher in males than females. A statistically significant difference was found between the sexes in all the parameters evaluated except for the intercondylar notch height parameter (P < 0.05). According to the results of our study, the mean intercondylar notch width index (NWI) and intercondylar notch shape index (NSI) in the total population were calculated as 0.88 +/- 0.18. There was no statistically significant difference between male and female values for NWI and NSI (P > 0.05). Discussion and Conclusion: In this study, finally, intercondylar notch classification was done. According to this, in 46.5% of cases, notch type, which defined as type A and 53.5% of the notches were identified as U type. None of the cases was classified as W type. Studies in which normal morphometric data are presented due to differences in races between skeletal structures have crucial importance. Therefore, the data obtained from our study are thought to be useful to produce specific knee prostheses.
