Biochemical and morphologic studies of cartilage from the adult human sacroiliac joint.
The cartilage of the adult sacroiliac joint contains type II collagen and a high concentration of glycosaminoglycan. Furthermore, large aggregating proteoglycans and link proteins were extracted from the sacral cartilage. In these respects the sacroiliac cartilage is similar to that in the peripheral joints. However, while the organization of the collagen in the sacral cartilage is typical of an articular cartilage, the organization of the ilial cartilage is very different, and throughout its depth it possesses narrow collagen fibrils arranged parallel to the articular surface.
