Retrospective Cross Sectional MRI Study of Morphometry of Menisci of Knee Joint

Introduction: Meniscal tears are commonly encountered in clinical practice and cause significant musculoskeletal morbidity. Most of the data available on Morphometry of menisci in Indian population are through cadaveric studies and very few MRI studies are available to substantiate the available data. Aim of the study: To gather data on the Morphometry of menisci in South Indian population and compare it with the existing literature. Material and Method: 100 MRI images collected retrospectively were used to study menisci. Height and width of MM and LM were measured both in sagittal and coronal planes. Results: It was observed that in both sexes the height of the Anterior horn of Medial meniscus was significantly higher than that of Lateral meniscus. Width of the Anterior horn and body showed significantly higher values in Lateral meniscus whereas width of Posterior horn of Medial meniscus showed significantly higher values in both sexes. Height of Medial meniscus in all the segments was higher in males though the difference was significant only in anterior horn and Posterior horn segments. Height of Lateral meniscus was significantly higher in males in all the segments. Conclusion: Results of this study will add to the existing literature on the Morphometry of menisci and will serve as a database for patients undergoing meniscal allografts. KEY WORDS: Medial meniscus, Lateral meniscus, Meniscal tears, musculoskeletal morbidity.
