    This study identifies galectin-3 as a potential plasma protein biomarker for knee osteoarthritis (KOA) through Mendelian randomization.

  • 2

    Galectin-3 showed a significant odds ratio of 1.07 for KOA, indicating a causal association supported by genetic evidence.

  • 3

    In vitro experiments demonstrated that galectin-3 stimulation increased inflammatory cytokines in macrophages, suggesting a pro-inflammatory role.

  • 4

    The findings highlight the need for specific molecular biomarkers in KOA to improve early intervention and treatment strategies.

  • 5

    Galectin-3's role in inflammation positions it as a potential therapeutic target for further research in KOA management.
