Each component plays its part in mobility
Synovial Membrane is a specialized layer of connective tissue lining that secretes synovial fluid into the joint cavity to help maintain articular homeostasis.
Synovial Fluid lubricates the joints to permit smooth movement. Articular cartilage relies on the synovial fluid and the compression and release that occurs with movement to maintain the flow of nutrients in and waste out (via the synovial membrane and associated vasculature).
Articular Cartilage provides a smooth joint surface and distributes forces evenly to the underlying subchondral bone. When healthy, it’s very smooth and has low friction,
allowing bones in a joint to glide over each other during movement. This is where most joint disease manifests.1
Subchondral Bone is the specialized bone just below the cartilage designed to absorb forces. It contains sensory nerves and blood vessels to help support bone health and can be the source of pain associated with osteoarthritis (OA).
