title: Abnormal softening in articular cartilage: its relationship to the collagen framework.
abstract: Abnormal softening in articular cartilage is related to the presence of collagen fibers strongly aligned in a radial direction. In this paper, a morphologic model is proposed that provides a mechanism by which these radial arrays can develop passively from the more random, 3-dimensional network of fibers observed in normal articular cartilage.
