Environmental Disruption of Circadian Rhythm Predisposes Mice to Osteoarthritis‐Like Changes in Knee Joint

Circadian rhythm dysfunction is linked to many diseases, yet pathophysiological roles in articular cartilage homeostasis and degenerative joint disease including osteoarthritis (OA) remains to be investigated in vivo. Here, we tested whether environmental or genetic disruption of circadian homeostasis predisposes to OA‐like pathological changes. Male mice were examined for circadian locomotor activity upon changes in the light:dark (LD) cycle or...
