Abstract
O steoarthritis has always been described as a disease caused by ?wear and tear? untilthe recent research into genomics followed by proteomics, made it clear that the pathogenesis of OA involves three important steps. First step is the damage to cartilage which may occur due to an injury, malalignment, overuse or obesity. Second step involves activation of inflammatory pathways following the injury. Various cytokines like IL-1, IL-6, TNF-α, prostaglandins, leukotreines have been implicated leading to increased activity of proteases likeMMPs. Third step is repair which tries to undo the damage but in the process produces structurally altered joint which further perpetuates the process of damage and inflammation. A look out for biomarkers of damage to joint or that of inflammation specific to OA may help in its early diagnosis. Toprevent/stop the self-perspicuous process of OA, the first step is prevent damage to cartilage. The second step is to block the inflammatory pathways; we already have NSAIDs & steroids but none of them act as ?DMARDS? which can modulate the pathogenesis of OA; they only give symptomatic relief. The cytokines targeted in animal models have been IL-1, TNF-α, and the results have been encouraging as far as IL-1 modulation is concerned. The third step at which intervention can be done is to correct the abnormal repair. IGF-1 & TGF-β pathways have been targeted in animal models and results again have been encouraging. With better understanding of pathogenesis of OA, we can now hope that one day we may be able to halt it early enough and prevent debilitating pain and disability.
