With the aid of theoretical analysis and load-bearing experiments the behavior of the menisci of the knee joint on static terms is investigated. According to the theoretically postulated energy-absorbing function of the meniscus there is shown a decrease of pressures acting on the meniscotibial joint from the inner to the outer parts. The invariable position of the meniscus, which had been seen on static strain, and the slight gaping of incomplete incisions of radial orientation are explained with the histomorphology of the meniscal system. The behavior of a bucket-handle incision is interpreted by the special stress distribution.
