Osteoarthritis (OA) is a debilitating degenerative disease affecting multiple joint tissues, including cartilage, bone, synovium, and adipose tissues. OA presents diverse clinical phenotypes and distinct molecular endotypes, including inflammatory, metabolic, mechanical, genetic, and synovial variants. Consequently, innovative technologies are needed to support the development of effective diagnostic and precision therapeutic approaches. Traditional analysis of bulk OA tissue extracts has limitations due to technical constraints, causing challenges in the differentiation between various physiological and pathological phenotypes in joint tissues. This issue has led to standardization difficulties and hindered the success of clinical trials. Gaining insights into the spatial variations of the cellular and molecular structures in OA tissues, encompassing DNA, RNA, metabolites, and proteins, as well as their chemical properties, elemental composition, and mechanical attributes, can contribute to a more comprehensive understanding of the disease subtypes. Spatially resolved biology enables biologists to investigate cells within the context of their tissue microenvironment, providing a more holistic view of cellular function. Recent advances in innovative spatial biology techniques now allow intact tissue sections to be examined using various -omics lenses, such as genomics, transcriptomics, proteomics, and metabolomics, with spatial data. This fusion of approaches provides researchers with critical insights into the molecular composition and functions of the cells and tissues at precise spatial coordinates. Furthermore, advanced imaging techniques, including high-resolution microscopy, hyperspectral imaging, and mass spectrometry imaging, enable the visualization and analysis of the spatial distribution of biomolecules, cells, and tissues. Linking these molecular imaging outputs to conventional tissue histology can facilitate a more comprehensive characterization of disease phenotypes. This review summarizes the recent advancements in the molecular imaging modalities and methodologies for in-depth spatial analysis. It explores their applications, challenges, and potential opportunities in the field of OA. Additionally, this review provides a perspective on the potential research directions for these contemporary approaches that can meet the requirements of clinical diagnoses and the establishment of therapeutic targets for OA.

“…Turyanskaya and co-workers 165,166 focussed on the analysis of bone by LA-ICP-MS and X-ray techniques for different purposes in two papers. In the rst, 165 a human bone-cartilage sample was used to directly compare LA-ICP-MS and mXRF spectrometry. Quantitative results were obtained for both techniques using the CRM IAEA H-5 (animal bone) and an in-house prepared cartilage standard.…”

“…18 Matrix-matched synthetic hydroxyapatite materials doped with analyte metals were developed to improve quantication of calcied tissues. 15,[19][20][21] However, issues arose from being unable to obtain matched ablation behaviour between the calibration material and the sample, 15 with neither ablation yield or normalised sensitivity reported. Previous hydroxyapatite standards suffered from elemental inhomogeneity with relative standard deviation (RSD) up to 32% due to grain size and poor uptake into the crystal lattice.…”
