Abstract
IntroductionThe knee-joint consists of three articulations in one joint. There are two condyloid joints between condyles of femur and tibia, and third joint is between patella and femur. It is a complex joint because the articular surfaces of the femoral and tibial condyles are not congruent to each other. The tibial menisci play important role in articulation by providing congruent articulating surfaces to tibia and femur.There is very few data related to the morphometric parameters of tibial menisci. Aim of this study was to measure and analyse the dimensions of tibial meniscus in cadavers. MethodsIn the present study, different parameters of tibial meniscus were measured after exposure of knee joint. These measurements were done with the help of digital Vernier calliper. Results and discussionMean length, width and circumference of medial meniscus were 42.28±3.71mm, 31.67±3.40mm and 101.46±6.89mm respectively. Mean widths of anterior horn, body and posterior horn of medial meniscus were 6.48±1.21mm, 8.37±1.54mm, 14.34±2.59mm respectively. Mean thicknesses of anterior horn, body and posterior horn of medial meniscus were 4.81±1.34mm, 5.80±1.25mm and 5.28±1.22mm respectively. Mean length, width and circumference of lateral meniscus were 32.73±3.08mm, 33.22±3.37mm and 97.61± 7.32mm respectively. Mean widths of anterior, body and posterior parts of lateral meniscus were 8.57±1.6mm, 9.79±1.71mm, 9.21±1.28mm. Mean thicknesses of anterior horn, body and posterior horn of lateral meniscus were 3.03±0.94mm, 6.53±1.07mm and 4.76±1.00mm respectively. DiscussionThese dimensions of the menisci might be the major factors that determine the location and the kind of injury to menisci.
