How are articular cartilages nourished?

Articular cartilages are nourished primarily through synovial fluid, which is produced by the synovial membrane lining the joint capsule. This fluid provides essential nutrients and facilitates the exchange of waste products. Additionally, since articular cartilage lacks a direct blood supply, the compressive forces during joint movement help to draw the synovial fluid into the cartilage, enhancing its nourishment and maintaining its health.
