Abstract
Knee osteoarthritis (KOA) represents a progressive and painful disease that in time can lead to loss of function and disability. Early diagnosis and correct treatment are essential in preventing the advancement of the condition to a stage where it can affect the quality of life. The development of new imagistic methods and devices can help detect changes in the structure of the join before the onset of symptoms. At the moment there are no disease- modifying drugs approved, so the current treatment is symptomatic, focusing on pain reduction, improving function and trying to prevent progression towards disability.
