interarticular fibrocartilage [L, inter + articulus, joint] , one of four kinds of fibrocartilage, consisting of flattened fibrocartilaginous plates between the articular cartilage of the most active joints, such as the sternoclavicular, wrist, and knee joints. The synovial surfaces extend over the fibrocartilaginous plates and attach to surrounding ligaments. The fibrocartilaginous plates absorb shocks and increase mobility. Compare circumferential fibrocartilage, connecting fibrocartilage, stratiform fibrocartilage.
