Özet

© 2018 The College of RadiographersIntroduction: The posterior tibial slope (PTS) is believed to be a risk factor for anterior cruciate ligament (ACL) injury. The aim of this study was to reveal the differences in terms of PTS measurements on lateral knee radiographs between ruptured and non-injured cases as well as between males and females in regard to ACL alignment. Methods: The study cohort included 92 patients (61 males and 31 females) with ACL rupture and 101 individuals (59 males and 42 females) who visited the Orthopedics Department but had no ACL injury. PTS measurements on lateral knee radiographs were compared by two blinded reviewers. The results were analyzed in terms of ACL injury and sex differences. The intraclass correlation coefficient was used to calculate interobserver agreements. Results: Notably, there was an excellent agreement between the reviewers with regard to PTS measurements. In addition, although a statistically significant difference existed in terms of PTS measurements between the patient and control groups (p < 0.0001), a significant difference was not observed between males and females (p = 0.179). Conclusion: Lateral knee radiographs are useful for PTS measurements to estimate the risk of ACL injury.
