Many targeted strategies have been proposed to identify OA onset and progression prior to presentation of clinical symptoms and radiographic changes. Emerging research has focused on the utility of certain biochemical markers (biomarkers) as potential precursors of OA. Serum biomarkers have been widely studied across disease spectrums for their ability to classify the following characteristics: cartilage damage during early preradiographic stages, disease activity, severity or burden of disease, prognosis prediction, and response to certain treatment approaches. These classifications may be useful for understanding the evaluation and the qualification of biomarkers related to OA.</p></div><div><h3>Objectives</h3><p>The purpose of this critical review is to summarize and evaluate the existing serum biomarkers currently proposed for the identification and evaluation of osteoarthritis onset and progression in 3 populations: healthy-, anterior cruciate ligament reconstructed-, and osteoarthritic knees using the BIPED (burden of disease, investigative, prognostic, efficacy of intervention and diagnostic) classification.</p></div><div><h3>Methods</h3><p>Articles that reported on serum biomarkers in individuals with healthy, anterior cruciate ligament reconstructed and osteoarthritic knees were collected from peer-reviewed sources available on Medline (January 1, 2000 through March 31, 2020).
