    Spatial proteomic mapping reveals early molecular changes in knee joints associated with osteoarthritis progression.

  • 2

    MALDI-MSI allowed localization of peptides in cartilage and subchondral bone, enhancing analysis of mineralized tissue.

  • 3

    Collagen-derived peptides and modifications linked to matrix remodeling were upregulated in subchondral bone beneath damaged cartilage.

  • 4

    Bone remodeling may occur before visible cartilage degeneration, indicating subchondral bone as an early OA progression marker.

  • 5

    Linking tissue proteomic signatures with synovial fluid signals could enable earlier assessment and monitoring of OA.
