Pathological change mechanism of Osteoarthritis (OA). Exercise relieves the pathological changes of OA by affecting the degradation of the ECM, apoptosis, inflammatory response, autophagy and changes of ncRNA. (A) Mechanism of pathological changes of OA through degradation of ECM, apoptosis, inflammatory response, and autophagy. (B) Mechanism of pathological changes of OA through ncRNA.
