title: [The morphological characteristics of osteoarthrosis].
abstract: Osteoarthrosis (OA) is a group of overlapping diseases that have various etiologies, but equal biological, morphological, and clinical outcomes. OA is characterized by degenerative and destructive changes in the articular hyaline cartilage, subchondral bone, spongiosis, synovium, capsule, and articular ligamentous apparatus. The clinical symptoms of OA are closely associated with morphological changes in articular tissue elements, primarily in the articular hyaline cartilage. Six stages that reflect the magnitude of changes in the hyaline cartilage and 4 degrees of the extent of the process along the articular surface are identified.
