Joint cartilage and periarticular tissues

Joint cartilage and periarticular tissues represent the collective anatomical structures that form and support functional joints, including hyaline cartilage, the synovial membrane, joint capsule, ligaments, and tendons. The primary biological role of these tissues is to facilitate smooth, low-friction movement and provide shock absorption to protect the underlying bone during physical activity (StatPearls, 2023). In various arthritic conditions, these tissues become the site of chronic inflammation and structural breakdown, driven by the overproduction of degradative enzymes and pro-inflammatory cytokines (NIH, 2022). While pharmacological interventions like NSAIDs, corticosteroids, and biologics are administered to treat joint-related diseases, they target specific molecular entities within these tissues rather than the tissue complex as a whole. Therefore, this term describes a physiological environment and disease site rather than a single, discrete therapeutic target (PubMed, 2021). Therapeutic strategies often focus on preserving the integrity of the extracellular matrix or reducing synovial inflammation to maintain joint mobility. Understanding the interplay between these tissues is crucial for developing regenerative therapies and managing chronic pain associated with musculoskeletal disorders.

Drugs acting within these tissues typically function by inhibiting inflammatory mediators (e.g., COX enzymes, TNF-alpha), providing mechanical lubrication (viscosupplementation), or modulating immune responses to prevent tissue degradation.
