Knee osteoarthritis (KOA) is increasingly recognized as a disease driven by low-grade inflammation in addition to mechanical degeneration. Among immune cells involved in joint homeostasis, synovial macrophages play a central role in modulating inflammatory responses. Recent evidence highlights the importance of macrophage polarization, particularly the imbalance between pro-inflammatory (M1) and anti-inflammatory (M2) phenotypes, in the progression of KOA. This narrative mini-review summarizes current insights into the role of synovial macrophage polarization in KOA, its molecular regulation, and its potential as a therapeutic target.
