Abstract:
The menisci of 180 knee joints of children below eight years of age were studied and compared with those of the adults reported by the same author in a separate study. As the child growing, the morphological changes of the medial meniscus in this series of specimens are: increasing of the relative width of its posterior part, decreasing of the ratio of the width of the intermediate part to its posterior part; increasing of the angle between its intermediate part and posterior part up to right angle; changing of its shape from C shape to G shape; and widening of its opening. All of these changes appear more rapidly around the age of one year. The morphological changes of the lateral meniscus accompanying the increase of age are: increasing of the relative width of its lateral part first and decreasing afterwards; decreasing of the ratio of the width of its opening to the length of its peripheral margin first and increasing afterwards; decreasing of the relative width of the popliteal sulcus and shifting of the position of this sulcus posteriorly. All of these changes appear also more rapidly around the age of one year and beyond eight years old. More rapid change of the menisci around one year of age may be correlated with the beginning of standing and walking. The formation of the disc-like meniscus was also discussed.
