Abstract:
The morphology of the menisci of 300 knee joints of the Chinese adults have beenstudied. Measurements are only taken in those specimens with known sex (male 100,female 60). In 48%, the width of the lateral part of the lateral meniscus is from1/3--1/2 of the whole width of the meniscus. The true disc like lateral meniscus ispresent in 3.67%. In 59.33%, the width of the posterior part of the medial meniscusis from 1/3--2/5 of the whole width of the meniscus. According to the size of theopening of the medial meniscus, it can be divided into 3 types, the intermediate typeis the most common one (48.71%). The transverse ligament and the menisco-femoralligament are present in 55.33% and 98.67% respectively. No statistical difference be-tween sexes or sides in the percentages of various patterns is found. Tle mean valueof the male is always greater than that of the female in various measurements, but theratio of these values of both sexes in each measurement is within the limits of 0.80--0.93.It means that the menisci of the male is larger than that of the female, but no statisticaldifference is present in the proportions between various parts of the meniscus in bothsexes. The morphology of the menisci in the Chinese and the Japanese is similar, exceptthe medial meniscus is thicker and the popliteal sulcus is wider in the Japanese. Incomparing the menisci between the Chinese and the Americans or Europeans, we foundthat in the Chinese the width of the lateral part and the sagittal diameter of the lateralmeniscus are larger; the transverse ligament and the menisco-femoral ligament presentmore; the popliteal sulcus, the width of the posterior part and the opening of the medialmeniscus are wider. The relationship of the morphology of menisci to the different oc-currence of injury in medial or lateral meniscus between the Chinese and the Americansor Europeans is discussed.
