Many elements are responsible for the balance in bone tissue, including those which constitute a substantial proportion of bone mass, i.e., calcium, phosphorus and magnesium, as well as minor elements such as strontium. In addition, toxic elements acquired via occupational and environmental exposure, e.g., Pb, are included in the basic bone tissue composition. The study objective was to determine the content of strontium, lead, calcium, phosphorus, sodium and magnesium in chosen components of the knee joint, i.e., tibia, femur and meniscus. The levels of Sr, Pb, Ca, P, Na and Mg were the highest in the tibia in both men and women, whereas the lowest in the meniscus. It should be noted that the levels of these elements were by far higher in the tibia and femur as compared to the meniscus. In the components of the knee joint, the level of strontium showed the greatest variation. Significant statistical differences were found between men and women only in the content of lead.
许多元素负责骨骼组织的平衡，包括构成骨量的主要成分，如钙、磷和镁，以及锶等微量元素。此外，职业和环境暴露中获得的有毒元素，如铅，也包含在基本的骨骼组织成分中。本研究的目的是确定膝关节（胫骨、股骨和半月板）中选定成分的锶、铅、钙、磷、钠和镁含量。在男性和女性中，Sr、Pb、Ca、P、Na 和 Mg 的含量均以胫骨最高，而半月板最低。值得注意的是，与半月板相比，这些元素的含量在胫骨和股骨中要高得多。在膝关节的组成部分中，锶的水平变化最大。仅在铅含量方面，男女之间存在显著的统计学差异。
