ABSTRACT. Osteoarthritis (OA) was previously considered primarily a degenerative disease associated with joint “wear and tear.” Nevertheless, recent studies indicate that chronic, low-grade inflammation is a central factor in its development. The aim of this review is to characterize the morphology of inflammation in OA, focusing on macrophage polarization mechanisms and the role of obesity. A literature review of the last 5 years was conducted using PubMed, MEDLINE, and eLibrary databases. The analysis focused on pathogenetic mechanisms of joint damage, macrophage polarization, and obesity’s impact on disease progression. The results of the analysis allow us to conclude that the morphology of inflammation in OA reflects a complex network of cellular interactions, in which macrophage polarization plays a pivotal role, and obesity serves as one of the factors precipitating this process.
