"Joint failure" may be the result of different pathological conditions. While in some arthropathies initial changes prior to secondary cartilage destruction may be observed morphologically, the early changes in "mechanically induced" osteoarthrosis are not well known. In the present paper the ultrastructural events, eventually leading to osteoarthrotic cartilage destruction are presented. From the morphological changes it is assumed that the primary lesion leading to cartilage destruction may be seen in the loss of the granular surface microstructures of cartilage that may be followed by an increased hydration and thereafter chondrocytic death with destruction of cartilaginous matrix.

UI MeSH Term Description Entries
D008854 Microscopy, Electron Microscopy using an electron beam, instead of light, to visualize the sample, thereby allowing much greater magnification. The interactions of ELECTRONS with specimens are used to provide information about the fine structure of that specimen. In TRANSMISSION ELECTRON MICROSCOPY the reactions of the electrons that are transmitted through the specimen are imaged. In SCANNING ELECTRON MICROSCOPY an electron beam falls at a non-normal angle on the specimen and the image is derived from the reactions occurring above the plane of the specimen. Electron Microscopy
D010003 Osteoarthritis A progressive, degenerative joint disease, the most common form of arthritis, especially in older persons. The disease is thought to result not from the aging process but from biochemical changes and biomechanical stresses affecting articular cartilage. In the foreign literature it is often called osteoarthrosis deformans.
