Knee osteoarthritis (KOA) is a chronic multifactorial pathology and a current and essential
challenge for public health, with a negative impact on the geriatric patient’s quality of life. The
pathophysiology is not fully known; therefore, no specific treatment has been found to date. The
increase in the number of newly diagnosed cases of KOA is worrying, and it is essential to reduce
the risk factors and detect those with a protective role in this context. The destructive effects of free
radicals consist of the acceleration of chondrosenescence and apoptosis. Among other risk factors,
the influence of redox imbalance on the homeostasis of the osteoarticular system is highlighted. The
evolution of KOA can be correlated with oxidative stress markers or antioxidant status. These factors
reveal the importance of maintaining a redox balance for the joints and the whole body’s health,
emphasizing the importance of an individualized therapeutic approach based on antioxidant effects.
This paper aims to present an updated picture of the implications of reactive oxygen species (ROS) in
KOA from pathophysiological and biochemical perspectives, focusing on antioxidant systems that
could establish the premises for appropriate treatment to restore the redox balance and improve the
condition of patients with KOA
