| Abstract: | To elucidate compositional changes of human ligaments by aging, the content of elements in anterior cruciate ligaments (ACLs)
and ligamenta capitum femorum (LCFs) was analyzed by inductively coupled plasma-atomic emission spectrometry. The subjects
consisted of 11 men and 7 women, ranging from 59 to 91 yr of age. With regard to the content of elements, the content of sulfur
and iron was significantly higher in the LCFs than in the ACLs. It was found in the ACLs that the content of sulfur decreased
gradually with aging, whereas the content of calcium, phosphorus, and magnesium increased progressively with aging. On the
other hand, it was found in the LCFs that the content of magnesium decreased gradually with aging, whereas the content of
phosphorus increased progressively with aging. The common finding that the content of phosphorus increased with aging, but
the content of iron decreased, was obtained in the ACL and LCF. Regarding sexual difference, it was found in both the ACLs
and LCFs that the content of phosphorus was higher in women’s ligaments than in men’s. |
