: diartrodial

Knee osteoarthritis (OA) is a highly prevalent joint disease, causing pain and disability in older people, and it can be characterized by progressive degradation of the diarthrodial joint tissues.

Examples

The diarthrodial joints in the human body allow for a wide range of motion, such as bending and lifting.
Although soft tissues within the diarthrodial joint have been successfully used to detect and monitor knee OA, changes associated with the subchondral bones are a promising imaging biomarker for assessing knee OA conditions 2-5.

Academic text (2017)
In a healthy person, the diarthrodial joints, like the elbow and knee, function smoothly to enable various movements.
During physical therapy, the focus is often on strengthening the muscles around the diarthrodial joints to improve mobility.

Morphology

diarthrodial = diarthrosis (opaque) = di + arthro + ial

The adjective is formed from the specialized medical noun 'diarthrosis', and the Greek combining forms are not transparent to general learners.

Etymology

The word diarthrodial breaks into parts: dia- meaning 'through' and arthro- meaning 'joint'. So a diarthrodial joint is one where the bones move freely at the joint, like your knee or elbow.
