Age related imbalance of chondrocyte clock function. Simplified model showing the loss of homeostatic balance in chondrocytes during aging: a in normal physiology, a rhythmic balance of anabolic and catabolic activities ensures tissue remodelling and repair occurs optimally; b disruption to rhythmic balance during aging leads to excess catabolism and subsequent tissue damage
