Abstract

Background: Posterior tibial slope (PTS) is a crucial radiographic measurement to determine the tibial plateau angle relative to its shaft.
Methods: In this study, PACS images related to 612 patients who had visited the hospital for reasons such as knee injury or pain, physical examination, or knee reevaluation and had undergone X-ray examination were examined. PTS measurements were obtained using the GE CENTRICITY PACS software and subjected to analysis.
Findings: The distribution of mean PTS in right and left angles revealed no significant difference between the two groups (P = 0.830). Comparing the mean PTS distribution between men and women, there was no significant difference in left and right PTS (P > 0.05). Additionally, comparing mean PTS between the right and left sides across different age groups showed statistically significant differences (P < 0.001).
Conclusion: This study identified the normal range of PTS values in knee joints of healthy Iranian adults, which can serve as a guide for personalized treatments. We hope that the results of this study will encourage knee prosthesis manufacturers to consider the obtained PTS measurements, as well as gender and age differences, in their product development for the Iranian population.
