Preferred Label : Osteoarthritis;
ICD-11 definition : 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.;
