A Cadaveric Study Indicating Clinical Significance Of Relation Between Area Of Menisci With Corresponding Tibial Plateau And That Of Distance Between Anterior Horn And Posterior Horn Of Menisci

ABSTRACT

Background: Menisci play a pivotal role in functioning of knee joint. It contributes to the smooth movements ofthe joint by improving congruence, weight distribution and proprioception. The injuries of the menisci candisable as they lead to degenerative changes. Meniscal transplantation is latest of the adopted procedures inorthopedic surgeries. Therefore a thorough anatomical knowledge of the meniscal parameters is an essentialneed.Objectives: The aim of the research was to study the variation in distance between anterior horn and posteriorhorn of menisci and to find out relation between area of the menisci and area of corresponding tibial plate.Materials and Methods: The study was conducted on 60 Menisci (30 Lower Limbs) from donated dead bodies toDepartment of Anatomy, Medical college, Baroda. Data was analyzed statistically using student’s t- test. P value< 0.05 is considered significant. Data is presented as mean + SD and analyzed with the help of Microsoft Excel.Result: In the study it was observed that on the medial side the distance between anterior and posterior horns is28.87 + 1.06 mm whereas on the lateral side, is 12.60 + 0.35mm. The ratio between the areas of the menisci to thetibial plate was observed as 58% for medial and 54% for lateral menisci.Conclusion: The anatomical knowledge of the dimensions of the menisci would prove to be helpful in guidingmeniscal transplantation with allografts. It will be useful to various orthopedic surgeons, radiologists, forensicexperts, anatomists and physiotherapists alike.
