It synthesises evidence and highlights key actions clinicians can take to support people to make sense of OA in helpful ways. Beliefs

Chronic musculoskeletal pain is highly prevalent and poses a significant personal, societal, and economic burden. Management of chronic musculoskeletal pain remains a challenge. Long-term use of common analgesic medications such as nonsteroidal anti-inflammatory drugs and opioids is associated with adverse events, and in the case of opioids, drug addiction. Additionally, many individuals do not experience

The intricate process of articular cartilage remodeling, pivotal for both physiological functions and osteoarthritis (OA) progression, is orchestrated through a balance of matrix synthesis and breakdown, which is mediated by matrix metalloproteinase enzymes (MMPs). At the heart of this remodeling lies the pericellular matrix (PCM), a specialized microenvironment encapsulating each chondrocyte and composed

Proteolytic cartilage extracellular matrix breakdown is a major mechanism of articular cartilage loss in osteoarthritis (OA) pathogenesis. We sought to determine the overlap of proteolytic peptides in matched knee OA cartilage and synovial fluid on a proteome-wide scale to increase the prospective biomarker repertoire and to attribute proteolytic cleavages to specific secreted proteases.
