This article is devoted to the urgent problem of studying the importance of hypothyroidism in the deformation
of the musculoskeletal system, in particular the knee joint in childhood. Analysis of the obtained data shows
degenerative - dystrophic changes in the hyaline cartilage of the joint surface of the tibia and condyle of the
femur expressed by vacuolization of the cytoplasm, most chondrocytes, necrobiosis and necrosis. In the
metaphysical zone of both bones, individual newly formed bone beams and cavities filled with fatty bone
marrow are revealed. The relief of the ossification line has a wavy trajectory. All this is characteristic of the
inferior development of bone-cartilage structures of the knee joint. Histological and histochemical studies
revealed significant dystrophic changes in the joint capsule, synovial membrane of the round ligament, leading
to underdevelopment of the elements of the knee joint. A characteristic feature of the synovial membrane is
diffuse detection of mucoid substances, both in the main substance and in the cytoplasm of fibroblasts.
Conducted comprehensive morphological, histological and histochemical studies allow us to characterize the
earliest changes in the elements of the knee joint during hypothyroidism, which, apparently, is associated with
metabolic disorders and is the cause of pathological development.
