A osteoartrite (OA) pode ser definida como um grupo de doenças diferentes, que compartilham características comuns, podem ter etiologias diferentes, mas levam a desfechos biológicos, morfológicos e clínicos semelhantes, afetando a cartilagem articular, o osso subcondral, os ligamentos, a cápsula articular, a membrana sinovial e os músculos periarticulares. A OA é a doença articular mais comum em pessoas com 65 anos de idade ou mais. Sua etiologia não é completamente entendida, mas vários fatores são relacionados a ela, como o gênero feminino, predisposição genética, distúrbios metabólicos e estresse mecânico excessivo. O diagnóstico da OA baseia-se, primariamente, na história clínica e no exame físico. As principais características radiográficas da OA são a presença do estreitamento/redução do espaço articular focal e não uniforme, presente nas áreas submetidas a maior pressão, além de cistos subcondrais, esclerose subcondral e osteófitos. | |||

Osteoarthritis (OA) can be defined as a group of distinct, but overlapping diseases, which may have different etiologies, but similar biological, morphological, and clinical outcomes affecting the articular cartilage, subchondral bone, ligaments, joint capsule, synovial membrane, and periarticular muscles. OA is the most common joint disease in persons 65 years of age and above. Its etiology is not fully understood, although there are several related factors, such as female gender, genetics, metabolism, and excessive mechanical stress. The diagnosis of OA is primarily based on clinical history and physical examination. The cardinal radiographic features of OA are focal/non-uniform narrowing of the joint space in the areas subjected to the most pressure, subchondral cysts, subchondral sclerosis, and osteophytes. | |||
